Weather in Nepal for September 2025

In September, Nepal experiences a transition from the monsoon season to the post-monsoon period, resulting in varied weather conditions throughout the month. At the beginning of September, the weather in Nepal is characterized by lingering monsoon showers and relatively high humidity.

The southern regions, including the Terai plains, may still receive significant rainfall, while the central and northern areas, such as Kathmandu and Pokhara, begin to witness a decrease in precipitation.

Temperatures during this time typically range from 20° to 28°, with cooler evenings providing a pleasant respite from the daytime heat.

By the end of September, Nepal undergoes a noticeable shift in weather patterns as the monsoon retreats further. The country experiences clearer skies and reduced rainfall, particularly in the central and northern regions.

Daytime temperatures tend to hover around 22° to 30°, offering comfortable conditions for outdoor activities and sightseeing. However, it's essential to note that weather patterns can vary across different regions of Nepal due to its diverse topography.

In the mountainous areas, such as the Everest region, temperatures may be significantly cooler, and trekkers should be prepared for potential fluctuations in weather.
