Most trekkers aim for two main windows: pre-monsoon (March–May) and post-monsoon (late September–November). Spring brings rhododendron blooms and warming days; autumn offers the crispest mountain views after the rains wash haze from the sky.
Winter (December–February) can be magical on lower trails—fewer crowds, sharp skies—but high passes may be closed by snow. Monsoon (June–August) suits rain-shadow areas like Upper Mustang or parts of Tibet more than the classic Nepal treks.
We help you match route, altitude gain per day, and buffer days for domestic flights, which are more weather-sensitive than many travellers expect.
