Nepal Weather & Climate: Monthly Averages

Nepal's climate is diverse, ranging from a subtropical climate in the lowlands to a cold high-altitude climate in the mountains. The country experiences five distinct seasons: summer, monsoon, autumn, winter, and spring. During winter, the Himalayas act as a barrier to cold air, resulting in relatively warm conditions south of these incredible mountains. In the Himalayas, winter brings cold to extremely cold temperatures, often accompanied by regular snowfall.

Best Time to Visit Nepal

The periods from October to November (autumn) and mid-February to May (spring) are often regarded as the best times to visit Nepal. After the monsoon, the skies clear up, bringing pleasant temperatures and spectacular views. In March and April, southern Nepal typically experiences spring-like to summer conditions, with temperatures ranging from 22°C (72°F) to 30°C (86°F). This period is marked by minimal rainfall and abundant sunshine.

Winter and Monsoon Seasons

Tourist numbers decrease during the winter months from December to mid-February but rise again from mid-February through May. From mid-June to early October, the monsoon season sets in, bringing daily rainfall and obscuring most of the Himalayas behind thick clouds.

Impact of the Monsoon

During the monsoon, some regions of the country become inaccessible due to flooding. Mountain trails turn slippery in the persistent rain, and travelers often have to navigate swollen rivers and flooded rice fields.
