Situated perfectly amidst two giant mountains, i.e., Ama Dablam(6,812m) and Lhotse(8,516m), this peak is popular among both amateur and professional climbers.

The Island Peak journey runs through many iconic settlements, lush forests, and green trails before reaching the base camp. And from the base camp, it’s all rugged trails and mountain views from all the ways. The top of Island peak provides an awe-inspiring panoramic view of the entire Everest region mountains. The whole Everest region mountains mean the Mt Everest, Mt Lhotse, Mt Cho Oyu, Mt Makalu, Mt Ama Dablam, Mt Nuptse, and several others.

    Climbing the Island Peak is possible throughout the year except for the Monsoon season(June, July, and August).

    September is the first month of the Autumn season that comes just after the departure of Monsoon season. So, the early-September sees some rainfalls as the monsoon is on the brink of farewell. But the raindrops of the Monsoon season washes all the dust from the terrains and vegetation.

    Island Peak Climbing with Everest Base Camp Trek

    Winter and Monsoon are the two off and less picked seasons for trekking and climbing in Nepal. Winter is the coldest season of all, and Monsoon is the rainy season. This is why most of the trekkers and climbers don’t pick these seasons for their adventures in Nepal.

    Yes, indeed, these seasons are not as easy as the peak seasons. With better preparations and right gears, the Island Peak Climb is possible during off-seasons, but not recommended. Let’s go through each of these seasons to know more about them:

    Winter Season(December, January, February)

    Winter means the season of snowfall and freezing temperatures. December, January, and February are the months of the Winter season in Nepal. With the arrival of the Winter season, the warmth of the Island peak area starts to fall. The summit of Island peak gets speedy wind during the Winter season, and temperature is also very cold.

    The temperature during the Winter season is chilly and freezing. The lower areas are a bit warmer than the higher regions. During the Winter season, the lower regions(Below 4000m) have a minimum temperature of -5°C and a maximum temperature of around 12°C.

    Similarly, the higher regions, i.e., above 4000m, have a minimum temperature around -15°C and maximum temperature near to 8°C. The temperature of the areas above 6000m is quite unpredictable. The summit temperature is even colder than the lower regions where the cold wind always blows.

    Island peak climbing during the Winter season is a complicated deal to complete. The professional climbers are only suggested for Island peak during Winter. Winter increases the difficulty level of the Island peak. With the right equipment and preparation, it is possible to climb Island peak. The snowy trails of Winter can be a new adventure for you.

    The Island trails are peaceful and less crowded during Winter. It is a different experience than the peak seasons like Autumn and Spring. The first few weeks of December are the most favourable trekking time of Winter. You will not get disturbed by crowded trails; you will just focus on the Island peak summit.

    Monsoon season(June, July, August)

    Throughout June, July, and August, the rain clouds revolve around the atmosphere of Nepal. Monsoon season is also known as the Summer season is the season of periodic rainfalls. It is the time of hot and humid temperatures as well. The sky is covered by the rain clouds that obstruct mountain views. But the picture after the rainfall is observable with clear views of mountains and washed terrains.

    The temperature during the monsoon is hot and humid before rainfall and a bit cold after the rain. The lower area’s(under 4000m) minimum temperature is around 2°C, and the maximum temperature is near 18°C. Similarly, the higher area’s(above 4000m) minimum temperature is around -2°C, and the maximum temperature is near 10°C. The lower regions get the most rainfall, whereas the higher areas get very few rains. Despite knowing these facts, people don’t like to trek or climb during monsoon season.

    Mid-monsoon is not the best time to climb Island peak. Because the mid monsoon period, i.e July month, is the peak time of rainfall. And due to the rain, the trails are muddy, slippery to trek on.

    However, the first few weeks of June are perfect for trekking and climbing. Early-June does not receive rainfall and trails are also peaceful. So, if you are opting for Monsoon season then the early-June is an ideal time. Carry enough and appropriate rain gears while trekking and climbing in Monsoon.

    What to expect in Monsoon season?

    • To walk on peaceful trekking trails
    • To choose from ample food and accommodation options
