Annapurna Base Camp Trek in 5月: what to expect

May is the warmest month before the monsoon. Valleys are hot and humid, afternoon cloud and thunderstorms become common, and haze can hide distant peaks. Early May is still a good trekking window; by late May the pre-monsoon build-up brings rain on some days and flights can be delayed. High routes are mostly free of snow. Trekker numbers fall through the month, so lodges are less crowded. Start walking early each day, carry rain protection, and keep a spare day in your schedule for weather. Mornings are for walking and views; use the afternoons for rest, and do not push a high crossing into the hours when cloud and storms build.

Annapurna Base Camp in May is warm in the valley and cloudy in the afternoon. The stone staircases around Chhomrong are hot, leeches begin at the lowest altitudes, and mornings at the 4,130 m top are the best chance for views before cloud arrives.
