Mt. Everest base camp trek is a heavenly paradise in Sagarmatha National Park in Nepal. It is the tallest mountain in the world and the weather forecast around there is very unpredictable. A trek to Everest base camp starts at an altitude variation of 2,800 m to 5,545 m. Nepal experiences four seasons, as below:
Autumn (Late September to November): This season is right after the Monsoon and all the haze goes down, and the views are as clear as crystal. This is the ideal time of year to travel to Nepal. All the visibility is clear and calm. The daytime temperature reaches up to 12 degrees centigrade, and nighttime temperatures drop to 2 degrees centigrade in September and October. November will be colder than the previous month.
Winter season (December to February): Winter is cold, but there is clear weather. If you are properly prepared for the cold temperature, the Everest base camp trek is always doable and you can enjoy it more as there would be fewer people around you. The daytime temperature will be about - 8 to - 10 and nighttime will be - 12 to - 18 degrees centigrade. However, there are still few people on this trek. In my experience, winter is better for the EBC trek due to a smaller number of people, clear visibility, and a great opportunity to see Ghoral, Musk Deer, wild Goat, and diverse flora and fauna. If you are okay with the cold, then plan your trek to EBC in the winter.
Spring (March to May): Spring reminds us of another big season for trekking in Nepal. The temperature remains moderate at 17 degrees Celsius during the day and cools during the night. Having little to no rain, thunder, or snowfall is common during the spring season. Another good thing to do this season is meet with Everest climbers at base camp and have a nice chat with tea/coffee.
Monsoon Season (Jun to Mid-September): This is a rainy season in Nepal. It rains heavily and leads to mudslides and flooding. But at altitudes above 4,000 m, there is very little to no rain. In the monsoon season, visibility is poor and there are cloudy skies. The average temperature is moderate, like 10 to 18 degrees Celsius, and rainfall is about 450 mm. But you still enjoy your trekking in the monsoon with its green surroundings.
