May marks the transition from spring to the monsoon season in Nepal, presenting a diverse range of climatic conditions depending on altitude and geographical location. Lower elevations experience increasing temperatures, often exceeding 30C (86F) in the Terai region, while higher altitudes in the Himalayas remain cooler, with daytime temperatures typically above freezing. This pre-monsoon period is characterized by occasional showers and thunderstorms, particularly in the afternoons and evenings, increasing humidity levels throughout the country.
Understanding these conditions is essential for planning activities such as trekking, mountaineering, or sightseeing. The relatively stable weather patterns, combined with warmer temperatures at lower elevations and blooming rhododendrons at higher altitudes, make May a popular time for visiting Nepal. Clear skies offer stunning mountain views, while the landscapes transform into vibrant green hues. This time of year provides a unique opportunity to experience Nepal’s diverse flora and fauna before the monsoon’s heavy rains arrive.
