Overview of the Season pattern in Island Peak
Island Peak is located in the eastern Himalayas of Nepal. The region is at a higher altitude so the weather can be a bit colder than in lower areas. The year can be broadly divided into four seasons: spring, summer, autumn, and winter. Each offers unique challenges and advantages for climbers.

Spring (March to May)
Spring is one of the most favorable times for climbing Island Peak. During this season, daytime temperatures range from 15°C (50°F) to 20°C (59°F), while nighttime temperatures can drop to between -10°C (14°F) and -5°C (23°F).
The weather is generally stable, with clear skies, mild temperatures, and relatively low precipitation, which ensures good visibility and pleasant trekking conditions. This period also offers a beautiful natural backdrop, with blooming rhododendrons (pink, white, and red) that add to the scenic beauty of the region.
Autumn (September to November)
Autumn is the crown jewel of seasons and is the perfect time to conquer Island Peak. The weather is a dream, with clear skies, excellent visibility, and temperatures ranging from 5°C (41°F) to 15°C (59°F) during the day and dropping to between -5°C (23°F) and -20°C (-4°F) at night.
This season offers stable and dry weather conditions, ideal for high-altitude climbing. The landscapes are a sight to behold, with the post-monsoon clarity unveiling breathtaking views of the surrounding peaks.
Summer (June to August)
Summer (June to August) brings in the monsoon season on Island Peak with increased rainfall and cloud cover. Daytime temperatures can reach up to 25°C (68°F), with nighttime temperatures ranging from 5°C (41°F) to 10°C (50°F). This season is marked by frequent showers and overcast skies, from drizzles to heavy downpours.
The trails become wet and slippery, making climbing conditions more challenging. Rain and clouds often reduce visibility, increasing the risk of avalanches and landslides.
Summer is a possible time to climb the island peak, but you may not have a chance to see the views of the mountain ranges you have desired.
Winter (December to February)
Winter is the coldest season on Island Peak, with daytime temperatures typically below freezing, around -5°C (23°F) to -10°C (14°F), and nighttime temperatures dropping below -20°C (-4°F). The winter months bring harsh weather conditions, including heavy snowfall and strong winds.
The days are shorter, and the extreme cold makes climbing more strenuous and challenging. The heavy snow and ice increase the technical difficulty of the climb, posing a greater risk even for experienced climbers.
Due to these extreme conditions, winter is not recommended for beginners and is generally less popular for climbing Island Peak.
