Everest Base Camp Trek in Mei: 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.

Everest Base Camp in May overlaps with the expedition season at base camp, so the trail is busy early in the month and quieter later. Afternoon cloud builds above Namche, and Lukla flights may be delayed as the monsoon approaches. Start Kala Patthar before dawn.

General seasonal guidance, not a forecast. Conditions change year to year; confirm weather, flights and trail status with your guide or lodge before you go.
