Nepal has four distinct seasons: spring, summer, autumn, and winter. The seasons highly influence the weather, climate, trail conditions, and peak climbing experience. Hence, choosing the best time for the climb is crucial. It also significantly influences the climbing conditions
Before deciding the best time to climb the Island Peak, you must learn about the seasons and their weather conditions. This article will provide you with all the information you need about the best time for the climbing season for Imja Tse. So, let us begin!
Understanding Island Peak
Geographical Overview
Island Peak, also known locally as Imja Tse, lies in the Everest region of Nepal. It is 6189 meters high and sits within the UNESCO World Heritage Site, Sagarmatha National Park. The Khumbu Himal is its parent range.
The Island Peak is a ridge extension from the south end of Mount Lhotse Shar. As mentioned above, a vast sea of snow surrounds the peak. It lies close to the point where the Imja and Lhotse Glaciers meet. Its geographical coordinates are 27° 55′ 14.84″ N latitude and 86° 56′ 6.58″ E longitude.
The trail to Island Peak is challenging, as its terrains are rough and rugged with steep slopes. Likewise, trekkers must cross ice slopes, crevasses, glaciers, and moraines. The unpredictable weather adds to the challenges.
Island Peak Trek takes 14 to 18 days, depending on the route. The distance from Lukla, the starting point of the trek, to Everest Base Camp, is 40 to 47 km (25 to 29 miles). The trek is an arduous journey but also a rewarding one.
Historical Significance
Eric Shipton, the leader of the Mount Everest expedition team, gave the peak its name in 1951. Later, in 1953, the British expedition team climbed Island Peak’s southwest summit as a practice for Everest. Tenzing Norgay, Charles Wylie, Charles Evans, Alfred Gregory, and seven Sherpas were part of the team.
Swiss climber Hans-Rudolf Von Guten and two Sherpas reached the summit in 1956, and many mountaineers attempt to climb the peak. Island Peak has become an acclimatization and a crucial training ground for higher Himalayan climbing expeditions. It has cultural significance to the local Sherpas of the Everest region. Most prefer to climb the peak as Mount Everest preparation rather than taking Everest Base Camp Trek.
Trekking Seasons in Nepal
Spring Season
The spring season, March to May, is the peak trekking season and best time to visit Nepal. Thousands of travelers visit Nepal at this time for trekking and climbing activities. Spring is the best time to climb Island Peak Trek. The weather is favorable, with a low precipitation level. Hence, the trails are dry and in good condition for trekking.
The best part about trekking in Spring is that the landscape thrives with color and vibrancy. Moreover, the Himalayan flora and fauna are the most active. The trails of Island Peak go through a dense forest of rhododendrons, which are in full bloom in springtime. En route, you can also see numerous blooming Himalayan wildflowers. Likewise, there is a chance that you will encounter rare wildlife along the trekking trails.
The days are warm and sunny in spring, with 9 hours of daylight. The average daytime temperature above 4000 meters altitude is around 17 degrees Celsius. Meanwhile, the nighttime temperature can drop to -10 degrees Celsius. The temperature at Island Peak summit is always below freezing.
Autumn Season
The next best and peak season for trekking in Nepal is autumn, which falls from September to November. It is also another ideal time for climbing Island Peak in Nepal. The stable weather, crisp air, and clear sky make it a popular time to trek. As a result, the trails are busy with trekkers. It is common to come across fellow trekkers along the route.
Due to the monsoon, the lower region can experience rainfall during early September. However, the rain washes away dust and impurities in the atmosphere and landscapes. Therefore, visibility is excellent in autumn. The vegetation looks lusciously green, and the views of the mountain vistas are crystal clear.
The average daytime temperature of high regions above 4000 meters is around 15 degrees Celsius. However, the temperature drops significantly at night and in the mornings. The minimum temperature can reach -15 degrees Celsius.
Winter and Summer (Off-Season)
Winter and summer are the off-seasons for trekking, and we do not recommend these two seasons to climb Island Peak Trek. The weather and climatic conditions are not ideal for trekking in these seasons, and most trekkers also avoid them.
Winter, from December to February, brings heavy snowfall and blizzards to the higher regions of Nepal. The temperature begins to drop and gets especially cold at higher altitudes. Heavy snow can block the high mountain passes, and the weather at the summit can get extremely harsh. The maximum temperature above 4000 meters is around 8 degrees Celsius, while the minimum can be around -15 degrees Celsius. Temperature above 6000 meters is unpredictable. Island Peak during winter is more challenging than in spring and autumn.
Summer or monsoon season, which runs from June to August, brings its own set of challenges. There is heavy rainfall all over the country, while the temperature is hot and humid. Rain clouds obstruct the views of the surrounding scenery and mountains. The maximum temperature above 4000 meters altitude is around 20 degrees Celsius, and the minimum is around -2 degrees Celsius. Due to rainfall, the trails are slippery and wet.
Best Time for Island Peak Trek by Month
Take a look at this detailed month-by-month analysis of optimal timing for Island Peak Trek:
January
The month is unsuitable for the Island Peak expedition or other high-altitude treks. Heavy snowfall may block the high mountain passes, and there are high risks of avalanches. The temperature of Island Peak at nighttime can drop up to -22 degrees Celsius. However, many extreme adventure seekers choose January for trekking.
February
As February begins, the days slowly become longer and clearer. However, during early and mid-February, there is still quite a lot of snowfall. The temperature above 5000 meters can reach up to -26 degrees Celsius. There is still a risk of strong winds and frostbite. However, as the month progresses, it starts to get warmer.
March
March is the transition period when winter changes to spring. The days are brighter and sunnier, and the flora and fauna become active. Hence, the green and luscious vegetation, blooming rhododendron forests, and colorful Himalayan wildflowers adorn the trekking trails. The temperature above 4000 meters is around 15 to 17 degrees Celsius at daytime and around -10 degrees Celsius at nighttime. It is a suitable time for trekking and climbing adventure in Nepal.

June
The monsoon enters Nepal in June and brings heavy rainfall across the country. The days become gloomy, with a lot of rainfall and a few thunderstorms. Hence, trekking during June is more challenging. The trails are wet and slippery, with a risk of landslides. The average temperature ranges between 20 to 35 degrees Celsius. Meanwhile, the nighttime temperature is around 20 degrees Celsius.
July
July also falls during the monsoon and summer seasons. Like June, this month also receives a lot of rainfall. Hence, the trails are wet and muddy and not suitable for trekking. The risk of landslides and mudslides persists. Likewise, the visibility is poor, and gloomy clouds obstruct the view. The daytime temperature is around 20 to 35 degrees Celsius, while the nighttime temperature is around 20 degrees Celsius.
August
August is the last month of summer and also peak monsoon time. Therefore, there is heavy rainfall with overcast skies. The visibility is extremely poor. The trails are unsafe for trekking, and there is a high risk of landslides. However, the hot temperature begins to drop slowly. The average temperature ranges around 15 degrees Celsius. Despite the heavy rainfall, the humidity level is still high.
September
The summer season transitions into autumn as September begins. It is the beginning of the peak trekking season in Nepal. However, there is still quite a lot of rainfall during early September. As the month progresses, the sky becomes clearer, and the monsoon leaves the country. It is the best time to enjoy the views of the Himalayas. The daytime temperature ranges from 5 to 15 degrees Celsius. The nighttime temperature can drop to -5 degrees Celsius.
October
The weather in October is delightful and favorable for trekking. It is neither scorching hot nor freezing cold and favorable time to embark in peak adventure. The rain from the monsoon cleanses the atmosphere and surrounding vegetation. Therefore, the whole landscape looks clean and vibrant. The daytime temperature ranges around 12 degrees Celsius. However, the nighttime temperature at higher elevations can drop to -20 degrees Celsius.
November
November is another excellent time to trek in Nepal. It is the beginning of the pre-winter season. The days are still sunny and warm, but they get slightly chillier as November progresses. You can still enjoy pleasant trekking during the daytime, with temperatures ranging from 5 to 10 degrees Celsius. However, the nighttime temperature drops to -20 degrees Celsius.
December
In December, winter begins in Nepal and is off-season for trekking. Most tea houses and lodges also close for winter. Experienced trekkers can still trek at this time with proper preparation. The weather at higher altitudes starts to become harsh and frigid. The temperature below 4000 meters is around 12 to -5 degrees Celsius. Meanwhile, temperatures above 4000 meters range from 8 to -15 degrees Celsius.
Preparation for the Trek
Physical and Mental Preparation
Island Peak Climb is an Alpine PD+ grade-level peak, which is slightly difficult. The trek is physically and mentally demanding. Unlike Mera Peak Climbing, which is another popular trekking peak in the Everest region, it does not require technical skill. Most mountaineers climb Island Peak to prepare for the Everest climb. However, any trekkers, including beginners with good physical fitness levels, can join the trek. Prior experience is undoubtedly helpful for climbing the peak.
Physical preparation will help to make your trek experience more comfortable. It is best to start preparing 3 or 4 months before your trek. You can undertake exercises and training that boost your physical strength, stamina, and endurance. Cardiovascular exercises such as running, jogging, cycling, swimming, etc., help increase your strength and stamina.
You can also hike while carrying some weight on your back. Likewise, you can also undertake rock climbing or learn basic mountaineering skills. These skills will be helpful during the Island Peak Trek and make your journey less strenuous.
While physical preparation is crucial for the trek, mental preparation is vital. The weather in the Himalayas is harsh and cruel. They can change at any time, and predicting them is impossible. The remote trails, the sense of isolation, and the physical strain can stress out many trekkers.
Therefore, trekkers should come mentally prepared. Research the trek and its challenges and familiarize yourself with the route. Physical and mental preparation plays a massive role in the success of your trek.

- Prepare yourself physically and mentally for the trek. Undertake exercises and training a few months before the trek to enhance your physical stamina, strength, and endurance. Research about the trek and its challenges to build mental resilience.
- Choose the right time to trek. Autumn and spring have the best weather and climates for trekking, but the routes are busier. If you want to experience quieter trails and enjoy the serene atmosphere, off-season is the right time. However, trekking in off-seasons comes with additional challenges.
