Weather & Best Season for Everest Trek

Weather in the Everest Base Camp trek is unpredictable. Sometime cloudy, sometime sunny. Make sufficient preparation for the trek.  Here are some weather basics to help ensure that you come to the Himalayas as well equipped and prepared to face anything.

Normally the nights are much cooler than the daytime hours in the Himalayas. During the day time, the temperature could reach as high as 25 degrees Celsius, only to drop down as low as -20 degrees Celsius in less than 24 hours. While there’s no way to know exactly what each day in the mountains will bring, the weather and temperature ranges tend to be somewhat predictable based on the month and season.

Spring – March / April / May / June

Spring happens to be one of the best times of the year to visit the Everest region, although because of this, it can become somewhat crowded. One can meet many other Everest climbers during this season and base camp is full of tents. The beautiful clear blue sky can be seen and the many different species of flower are visible in the lower altitude.
During springtime, the average temperature is 17 degrees C with a maximum of 25 degrees C during sunny days and a minimum of -15 degrees C in the morning and at night for areas above 4000 meters.

Monsoon Season – July / August through Mid-September

This season is not really recommended to travel as it rains in the lower altitudes, below 3500 meters. In areas above 4000 meters, it rains sometimes and although it is also sometimes dry, very few people travel during this season. There are positives to trekking during the monsoon months, however. The excess rainfall can provide ample chance to see spectacular views of the waterfall and it’s also the best season to avoid the crowds.

The maximum temperature during the monsoon season averages 25 degrees C during sunny days with a minimum -15 degrees C in the morning and night at areas above 4000 meters. The average temperature tends to hover around a comfortable 18 degrees C.

Autumn Season – End of September / October / November

Similar to springtime, autumn in the Everest region is also a crowded season, but it’s one of the best times to trek. While it lacks the beauty of flowers, the clear blue sky can be seen, affording incredible views from just about every angle. The average temperature during the fall is 15 degrees C with a maximum temp of 20 degrees C during sunny days and a minimum of -10 degrees C in the morning and at night, for areas above 4000 meters altitude.

Regardless of time of year, trekkers should always plan accordingly and bring clothing for both cooler and warmer temps. Layering is always recommended, as are pants that can double as shorts. For a full list of clothing and materials to bring to account for various temperatures and weather changes that can occur in the Everest region, visitors should work closely with their travel provider. This will ensure that the adventure will be enjoyable no matter what the weather and that every possible scenario will be accounted for ahead of time.
