When is the best weather for flights to view Everest?


Generally speaking Everest viewing flights occur all year around and leave from Kathmandu airport. However there are no guarantees that you will see Everest due to weather conditions. Due to it's location the weather surrounding Everest is often volatile and changes hourly.

However the local airlines that arrange the flights will cancel a flight is the weather is obviously too cloudy that morning.

On average Everest flights are taken first thing in the morning. The earlier (or first flights) offer the best chance at clear weather.

The best months for Everest flights are the low precipitation months shown above - Nov, Dev, Jan, Feb.

When is the best weather for trekking in Nepal from Kathmandu?


Treks departing from Kathmandu are no different weather wise than any other part of Nepal aside from localized condition due to weather conditions.

Peak trekking weather months are October-November-December.

Please see my guide on the best times of the year to go trekking in Nepal for more precise information.


When is the best weather to visit Kathmandu?


Kathmandu has no extreme weather seasons so possible to visit Kathmandu at anytime of the year.

However there is a winter season Nov-Mar where it can get cold, especially at night. It rarely snows in Kathmandu.

During monsoon season streets can often get clogged with rain water. Heavy downpours usually only last 1 hour.

Interestingly Pokhara has a slightly differenct weather climate. So do check out what the weather is like in Pokhara.
