May weather forecast
Nepal

May in Nepal marks the end of spring and the beginning of summer, characterized by rising temperatures and a significant increase in rainfall. In the capital city Kathmandu, situated in the hilly mid-region, average temperatures range from 15°C (59°F) to 30°C (86°F). The lowland Terai regions experience higher temperatures, generally fluctuating between 25°C (77°F) and 40°C (104°F). Meanwhile, in the high Himalayan regions, temperatures typically vary from 10°C (50°F) to 20°C (68°F).

Pokhara, a city nestled between serene lakes and towering mountains, sees average temperatures ranging from 20°C (68°F) to 33°C (91.4°F). The frequency of rainfall intensifies during this month, often causing occasional disruptions to the visibility of the Himalayan peaks.

The Terai plains, by May, have fully embraced the tropical climate. The region is hot, humid, and experiences increasing rainfall, a stark contrast to the cooler and drier conditions experienced during the winter months.

May experiences a significant increase in precipitation compared to April, making it one of the wettest months of the year. The arrival of the pre-monsoon showers indicates the transition towards the full-fledged monsoon season. These rain events, while still intermittent, are more intense and frequent.

The accessibility of high altitude trekking routes such as the Everest Base Camp and the Annapurna Circuit starts to decrease due to the increasing likelihood of heavy rain and sudden weather changes. Meanwhile, the increasing heat, humidity, and rainfall in the Terai region render wildlife viewing at the Chitwan National Park less optimal towards the end of the month. However, the Kathmandu Valley, while experiencing warmer temperatures and occasional showers, continues to offer pleasant trekking conditions.
