When thinking about going to the Everest Base Camp – EBC for a short – Trek, there are several factors to be consider. Understanding the best time to trek to Everest Base Camp is essential for a safe and enjoyable experience.
Assuming you are not tied to a certain time with regard to your annual leave, you should pick the time of year that is right for you in terms of availability (sometimes it is extremely hard to get a domestic flight or accommodation on the trail), your ability (harder to hike in snow or rain), and what you plan to do (photography, meet other trekkers, sample local life, or simply embrace the great outdoors).
Most of the information you will read says ‘spring’ and ‘autumn’ are the best times to trek Everest base camp. While this is true, this shouldn’t deter you from considering other times of the year. And if you do go during spring and autumn, no one can guarantee that during your particular 14-day visit, the weather will behave itself!
Let’s take a closer look at the different seasons in the Everest Region.
Everest Base Camp in Spring: March to May
March to May is the busiest time in the Everest region for trekking and climbing. With clear skies and glorious weather, it attracts visitors from all over the world.
Since this was the best time to attempt to summit the highest mountain in the world, Mount Everest, it is no surprise that the first successful summit took place on 29 May 1953. Every year we see a number of different expeditions on the mountain around this time – just waiting for what is commonly known as the good ‘weather window’ to push on for the final ascent.
While climbing expeditions will be extremely well prepared for the cold weather – and it is extremely cold on the mountain – potential trekkers may be more interested to know how cold it will be for them on the route to Everest Base Camp and what they should carry in the way of clothing.
Temperature: you might be surprised to know you may get a maximum of 20 degrees centigrade during the daytime and around 5 degrees at night. Early mornings when you start your trek for the day and evenings will be cold, but during the day, you may want to ditch the heavier jacket and bask in the high-altitude sun!
What to Bring: The one word is “layers.” You want to be able to wrap up warmly when it is chilly yet keep cool when the weather is warmer, and the hiking is heating you anyway. So plenty of layers that are easy to take off (and then carry) on the trail. Material that absorbs sweat is best for that first layer next to your skin, and a good fleece or down jacket is the final protection against the cold. And, like we already said, the weather is not guaranteed, so don’t prepare only for those 20-day time degrees – it may be much cooler!
Benefits of spring: Like spring in many locations, at the lower altitudes, this is the time to appreciate the lovely flowers and perhaps spot some wildlife – you are travelling in the Sagarmatha National Park, after all. The sky will be blue, and the snowy mountains will glow against this clear backdrop. There will be less likelihood of flight cancellations or delays due to bad weather.
Disadvantages of Spring: The main disadvantage is the number of people on the trails. Sometimes it may be difficult to get accommodation for the night unless you are traveling with a guide who has pre-booked for you. On the other hand, there will be plenty of company to share your stories in the evenings.
Tips for Trekking to Everest Base Camp in March To May
- Start Early: Begin your trek early in the morning to make the most of the clear weather before clouds form in the afternoon.
- Hydrate and Acclimatize: Spring temperatures may fluctuate, so stay hydrated and take proper acclimatization breaks.
- Photography Opportunities: Use the blooming rhododendrons as a colorful backdrop for your photos.
- Book in Advance: Accommodations can fill quickly, so pre-book your lodges if possible.
Everest Base Camp in Monsoon: June to August
June to August is the monsoon period in Nepal. In some areas, such as Kathmandu, pre-monsoon rain can cause just as much problem as the monsoon itself. On the other hand, some areas, such as Upper Mustang, fall in the rain shadow, so rainfall is extremely low at any time of year.
In the Everest Region, you should expect rain at the lower altitudes (below 3,500m) and some at higher altitudes. Again we cannot be sure of the exact weather.
Temperature: it is also quite warm (18 degrees centigrade) in the daytime. But if it rains, the temperature will, of course, drop considerably. Early mornings and nights will be very cold, and you should be prepared for it to drop well below freezing.
What to Bring: You should carry waterproof trousers (that slip over your normal trekking ones) and a waterproof jacket. Remember to bring a waterproof cover for your backpack and your day pack. Footwear should also be waterproof.
Benefits of monsoon: the only advantage is that the trails will be very quiet. Not many people chose to trek this season, so there should be plenty of choice regarding accommodation. At lower altitudes, the forests will be washed clean, and the rivers running fast, forming waterfalls in various places. The skies will be very atmospheric – white fluffy clouds, then dark, threatening rain clouds.
The disadvantage of monsoon: the weather! Not many people enjoy walking in the rain or climbing over slippery trails. Although if the rain doesn’t bother you, when you get to higher altitudes, with less likelihood of rain, it will be glorious to have the trails to yourself. Another disadvantage is that flights are often delayed due to the weather. But if you are not tied to an exact timetable (never book your international flight the next day to a domestic flight), this can be turned into an advantage of another couple of days in the mountains!
Tips for Trekking to Everest Base Camp in June to August
- Start Early: Begin your trek early in the morning to avoid afternoon rain showers, which are frequent during the monsoon season. Mornings are usually clearer and more pleasant for trekking.
- Pack Waterproof Gear: Bring a waterproof jacket, trousers, and backpack covers. Ensure your trekking boots are waterproof and have a good grip to handle wet and slippery trails.
- Protect Your Belongings: Use dry bags or zip-lock pouches to keep electronics, clothes, and important items safe from moisture.
- Choose Rain-Shadow Regions: Opt for trekking routes in rain-shadow areas such as Upper Mustang or Dolpo, which experience minimal rainfall even during the monsoon.
- Stay Informed About Weather Conditions: Keep track of weather forecasts and consult your guide to plan the safest routes and timings.
- Watch for Slippery Trails: Trekking poles are essential for stability on muddy and slippery paths. Walk carefully, especially on steep descents.
- Prepare for Bugs: Carry insect repellent and wear long sleeves and trousers to protect against leeches and mosquitoes, especially at lower altitudes.
- Add Buffer Days: Plan extra days in your itinerary to accommodate flight delays or weather-related disruptions, which are common in the monsoon season.
- Take Advantage of the Quiet Trails: Enjoy the solitude, as fewer trekkers on the trail means less crowded tea houses and a more peaceful trekking experience.
- Capture the Unique Scenery: Use the lush greenery, vibrant flowers, flowing rivers, and atmospheric clouds as backdrops for stunning photos.
Everest Base Camp in Autumn: September to November
September to November is the second most popular and best time to trek Everest base camp. Things are pretty much the same as in the spring – clear blue skies and wonderful mountain views. And being a popular time, the trails will be busy again, and lodges will be pretty full.
Temperature: again, similar to spring, it will be warm in the daytime and cold in the mornings and nights. However, the later you get into autumn, the colder it will get. There is a possibility of snowfall which will bring the temperature down even further.
What to Bring: Layers of clothing are essential, and you should bring waterproofs in case of snow. Discuss with your trekking agent whether you will need to bring (or hire) special footwear, such as crampons, in the event of snow on the trails.
Advantages of autumn: the beautiful clear mountain views and the relatively warm days. It is festival time in Nepal this season so everyone will be in an even more jolly mood than usual.
Disadvantages of autumn: again, this is a busy time with trekkers and climbers all making their way to their various treks and climbs. As it is festival time, many porters and guides will be taking leave, so at this time, it is very wise to book your trek well in advance. At the beginning of the season, rain in the lower altitudes is still possible. Rain in the lowland areas of the country can also cause flight delays. At the end of the season, there is the possibility of snowfall. Both rain and snow will make the trails more slippery. But the majority of this season is just wonderful in terms of weather.
Tips for Trekking to Everest Base Camp in September to November
- Start Early: Begin your trek early in the morning to take advantage of the crystal-clear skies that are common during autumn. Early starts also help avoid any afternoon haze that may develop.
- Book Accommodations in Advance: Autumn is the busiest trekking season, with many trekkers heading to popular routes. Pre-book your lodges to secure your stay, especially in villages like Namche Bazaar or Dingboche.
- Pack for Mild Days and Cold Nights: Daytime temperatures are pleasant, but nights can get chilly at higher altitudes. Carry layers, including a warm jacket, gloves, and a hat for the evenings.
- Stay Hydrated and Acclimatize: Drink plenty of water and take acclimatization breaks to prevent altitude sickness as you ascend to higher elevations.
- Enjoy the Stunning Views: Autumn offers the best visibility of the year, with unobstructed views of snow-capped mountains, making it an ideal season for photography and sightseeing.
- Carry Trekking Poles: Use trekking poles to maintain stability on trails, especially if you encounter loose rocks or steep sections.
- Prepare for Crowded Trails: Be prepared for busy trails and shared spaces in tea houses, as this is the peak season for trekking in Nepal.
- Embrace the Festive Atmosphere: Autumn coincides with major Nepalese festivals like Dashain and Tihar, providing a unique opportunity to experience local culture and celebrations.
- Bring a Good Sleeping Bag: While tea houses provide blankets, higher-altitude villages can be very cold at night. A sleeping bag rated for sub-zero temperatures is essential.
- Plan for Buffer Days: Although the weather is generally stable, it’s wise to include a couple of extra days in your itinerary to account for unexpected delays, especially in flight schedules.
Everest Base Camp in Winter: December to February
December to February is not the best time to be in the mountains. Especially if you are inexperienced and/or hate the cold. Days are short, and nights are long. The way may be misty and the cold bone-chilling. But if you don’t mind the cold, you will have most of the trails to yourself.
Temperature: nights can drop down lower than -20 Celsius, and days will only rise to around 5 degrees.
What to Bring: You will want to bring warm clothing and a good sleeping bag for this time of year. Waterproof trousers and jackets should protect you from falling snow and snow underfoot. Remember those waterproof boots also.
Advantages of winter: unless you are experienced in hiking in snow and cold conditions and remember this is not a country where your lodge will have heated sleeping rooms or a sauna to warm you at the end of each day. You may wonder what advantages there possibly could be. But the trails and lodges will be empty, and you may feel like you have the whole countryside to yourself , a definite and wonderful advantage. The mountains will be snowy giants with high winds blowing snow across them, creating a unique view of these famous peaks.
Disadvantages of winter: those empty trails mean there are fewer people around to ask directions, and snow can quickly cover the trails, making them hard to see. Some lodges close as the owners go to lower places to spend the winter. It can be hard going on the trails, so you should consider your physical ability. And it’s cold!
Tips for Trekking to Everest Base Camp in Winter (December to February)
- Dress for Extreme Cold: Pack thermal base layers, an insulated jacket, gloves, a hat, and warm socks. Layering is essential to manage temperature changes throughout the day.
- Carry a High-Quality Sleeping Bag: Nights can drop below -20°C, so bring a sleeping bag rated for extreme cold to stay warm and comfortable in unheated tea houses.
- Wear Waterproof and Insulated Gear: Waterproof jackets and trousers will protect you from snow and cold winds, while waterproof boots with good grip are crucial for trekking on snowy trails.
- Start Early: Days are shorter in winter, so begin your trek early in the morning to make the most of daylight. Plan to reach your destination before nightfall.
- Plan for Solitude: While winter trekking is less crowded, many tea houses at higher altitudes may be closed. Confirm open accommodations in advance or trek with a guide who can help secure lodging.
- Hydrate and Stay Nourished: Cold weather can reduce your sense of thirst, but staying hydrated is crucial. Warm meals and hot drinks available at tea houses will help maintain your energy levels.
- Prepare for Snow-Covered Trails: Trekking poles and gaiters are essential for stability and to prevent snow from getting into your boots.
- Allow Flexibility in Your Itinerary: Snowfall can slow your progress or block certain trails. Build extra days into your schedule to account for delays or reroutes.
- Protect Your Electronics: Batteries drain quickly in extreme cold. Carry a power bank and keep your electronics close to your body to prevent them from freezing.
- Embrace the Quiet Trails: Winter trekking offers unparalleled tranquility, with snow-covered landscapes and peaceful trails largely free from other trekkers.
While winter trekking requires more preparation and tolerance for cold, it rewards those who brave it with serene trails, breathtaking snowy vistas, and a unique sense of adventure.
Is It Safe to Trek Everest Base Camp in Winter?
Trekking to Everest Base Camp in winter is safe for well-prepared trekkers with proper gear and experience. However, the season poses unique challenges such as extreme cold, shorter daylight hours, and snow-covered trails, requiring careful planning and a higher level of physical and mental endurance.
How Cold Can It Get?
Temperatures during winter can drop significantly, especially at higher altitudes. Nighttime temperatures at Everest Base Camp often plunge to -15°C to -20°C (5°F to -4°F) or lower, while daytime temperatures in the lower regions remain moderately cold but bearable. Proper layering and high-quality insulation are essential to stay warm.
What Are the Biggest Challenges and Risks of Winter Trekking on the Everest Base Camp?
- Extreme Cold: The frigid temperatures can lead to frostbite or hypothermia if not adequately prepared.
- Snow and Ice: Trails can become slippery or blocked by heavy snow, making navigation and trekking more difficult.
- Altitude Sickness: The risk of altitude sickness remains prevalent, as cold temperatures may slow acclimatization.
- Limited Facilities: Some tea houses and lodges may close during winter, reducing accommodation options.
- Isolation: Fewer trekkers on the trail mean reduced chances of help in case of emergencies.
Proper preparation, including gear, physical fitness, and an experienced guide, is crucial to overcoming these challenges and enjoying a winter trek to Everest Base Camp safely.
Accommodation and Food in Winter
During the winter months, many teahouses along the Everest Base Camp trek remain open, though fewer are in operation due to lower numbers of trekkers. In areas where teahouses are closed, you may need to rely on local guesthouses or the support of guides who have connections with families willing to host trekkers.
These arrangements can sometimes be more basic, and the availability of food may be limited. Typically, warm, hearty meals like dal bhat (lentil soup with rice), noodles, and soup are available. However, be prepared for a more limited menu compared to the high season.
Gear and Clothing Essentials during Winter
Winter trekking at high altitudes requires the right gear to ensure your safety and comfort. Essential items include:
- Layered Clothing: A moisture-wicking base layer, followed by an insulating middle layer (fleece or down), and a waterproof, windproof outer layer.
- Down Jacket: For warmth in the evenings and at higher elevations.
- Thermal Gloves and Hat: To protect against frostbite in freezing temperatures.
- High-Quality Trekking Boots: Insulated boots for warmth and stability on snow or icy trails.
- Sleeping Bag: Rated for sub-zero temperatures to ensure warmth while sleeping at high altitudes.
- Gaiters: To protect your legs from snow and ice.
- Trekking Poles: For stability, especially in icy conditions.
Permits and Health Concerns
When trekking in winter, ensure you have all necessary permits, including the Sagarmatha National Park Permit and the Khumbu Pasang Lhamu Rural Permits.
Health-wise, winter trekking brings unique challenges:
- Altitude Sickness: Cold, dry air and the thinner atmosphere at high altitudes can exacerbate symptoms. It’s essential to acclimatize properly and stay hydrated.
- Frostbite Risk: Exposure to extreme cold can lead to frostbite, particularly in extremities like fingers, toes, and ears.
- Dehydration: Dry winter air can lead to dehydration, even when it’s cold. Drink plenty of water and consume high-calorie foods to maintain energy levels.
What are the alternative arrangements for food and shelter if teahouses are closed during winter?
If teahouses are closed or unavailable during winter, alternative arrangements can be made through:
- Local Guesthouses: Some local homes may offer shelter and meals, but these options are more likely to be found in larger settlements like Namche Bazaar or Lukla.
- Camping: If no indoor shelter is available, you may need to set up camp, though this is only recommended with an experienced guide and appropriate winter camping gear.
- Support from Guides: A guide familiar with winter trekking may arrange for meals and accommodations with local families or private homes along the trail.
Tip for Avoiding Peak Season Crowds
The Everest Base Camp trek is most crowded during spring (April-May) and autumn (October-November). To avoid the peak-season crowds, consider trekking in the shoulder seasons (March or late-November to early December). While the weather may not be perfect, the trail is significantly less crowded, offering a more peaceful trekking experience.
Importance of Choosing the Right Season for the Everest Base Camp Trek
Choosing the right season for trekking to Everest Base Camp is crucial for ensuring a safe, comfortable, and enjoyable experience. Just like the Manaslu Circuit, the best times to trek Everest Base Camp are during the spring (March to May) and autumn (September to November) months. These seasons offer several benefits, including:
- Ideal Trekking Conditions: Well-maintained trails with fewer obstacles and more teahouses open to accommodate trekkers, ensuring a smooth journey.
- Clear Skies: You’ll have the best chance of seeing stunning panoramic views of Everest and the surrounding peaks.
- Moderate Temperatures: The weather is relatively mild, making the trek more comfortable, especially at higher altitudes.
- Fewer Risks: There is a reduced risk of snowstorms, heavy rainfall, and slippery trails, which can make trekking dangerous during the monsoon or winter months.
When is the Best Time to Trek Everest Base Camp?
The best time to trek to Everest Base Camp is during the pre-monsoon (spring) and post-monsoon (autumn) seasons, similar to the Manaslu Circuit trek. These periods offer the most favorable conditions for trekking, including:
- Spring (March to May): Clear skies, moderate temperatures, and breathtaking views of Everest and the surrounding peaks.
- Autumn (September to November): Crisp, clear weather with mild temperatures, ideal for trekking.
During the monsoon season (June-August), heavy rainfall can make trails slippery, increase the risk of landslides, and reduce visibility. In the winter season (December-February), freezing temperatures at higher altitudes can make the trek more challenging, especially for those who are not experienced with cold weather trekking.
Choosing the right time ensures better weather, safer trails, and a more enjoyable experience on the Everest Base Camp trek.
