Nepal Trekking

October and November are the best months for trekking. The air is clear, the vegetation still lush after the monsoon, and both day and night temperatures are pleasant. December and January are colder (especially at higher altitudes) and generally dustier. High passes, like Thorong La on the Annapurna Circuit, can be closed and you need more equipment. Everest looks bare as it has very little snow cover. March and April are hazy, though in March, rhododendrons are particularly attractive. May is very hot and quite dusty and streams do not carry much water. The monsoons (June to Mid September) are wet, though you may get breaks of 3 or 4 days in the rain. Clouds can lift to give you some good mountain views. Equipment may feel a little damp. Weather in late September is unpredictable, but the trails are much less crowded, and hence, more pleasant. Leeches can be unpleasant in damper places.
