Plan around the monsoon
Is it monsoon in Nepal?
Nepal's climate changes dramatically with altitude, more than almost anywhere else in this dataset. Nepalganj, in the flat Terai plain along the Indian border, shares the same climate as the Indo-Gangetic plain of northern India: a mild, sunny winter, scorching pre-monsoon heat from March to June, and a heavy monsoon from June to September, when July and August alone can bring well over 300mm each. Kathmandu and Pokhara, in the mid-hills, run much milder thanks to elevation, though Pokhara sits directly in the path of monsoon currents forced upward by the Annapurna range, making it by far the rainiest city in the country, with July alone averaging close to a meter of rain.
Further into the mountains, Jumla and Namche Bazaar, both enclosed by peaks at higher elevation, are sheltered enough that the summer monsoon reaches them only weakly, a fraction of what falls on Pokhara at a similar time of year. Both also see winter nights drop well below freezing, and can receive snow even during their driest months. Nationwide, the best time to visit is historically November through February, avoiding both the summer monsoon and the plains' pre-monsoon heat, though spring and autumn, especially March, April, and mid-October to mid-November, are separately recommended for trekking in the hills and mountains.
Frequently asked questions
Does Nepal have one climate?›
No. Nepal's climate splits sharply by altitude: a subtropical climate with a rainy season in the flat southern Terai plain, a temperate climate in the mid-hills, including Kathmandu and Pokhara, and a cold mountain climate in the high Himalaya.
What is the best time to visit Nepal overall?›
November through February is historically the best window nationwide, avoiding both the summer monsoon and the intense pre-monsoon heat of the plains. For trekking specifically, spring (March and April) and autumn (mid-October to mid-November) are separately recommended.
Why is Pokhara so much rainier than Kathmandu?›
Pokhara sits at the foot of the Annapurna range, where southern monsoon currents are forced upward by the mountains, producing far more rain than Kathmandu or the rest of Nepal's mid-hills.
Is Nepal a good destination for trekking?›
Yes, and timing matters. Spring and autumn, especially March, April, and mid-October to mid-November, are historically the best windows, avoiding the winter cold at altitude and the summer monsoon's rain and cloud.
Does the monsoon reach the high mountains of Nepal?›
Only weakly in some sheltered areas. Jumla and similar mountain-enclosed valleys receive only a fraction of the rain seen in the mid-hills, since the surrounding peaks block much of the monsoon's moisture.
Does it snow in Nepal?›
It depends on elevation and location. Kathmandu, despite cold winter nights, almost never sees snow, while higher areas like Namche Bazaar can receive snow even during the dry winter season.
Do tropical cyclones affect Nepal?›
Nepal is too far from the sea to be directly hit by tropical cyclones, but the remnants of cyclones affecting India, usually from the Bay of Bengal, can bring heavy rain to the plains and snow to the mountains, occasionally triggering avalanches, as happened in October 2014 and again in late 2025.
