Best Season to Visit Nepal

Nepals climate varies with its topography and altitude. It ranges from the tropical to the arctic. The low-land Terai region with its maximum altitude to approximately 305m, which lies in the tropical southern part of the country, for instance, has a hot and humid climate that can rise above 45 Degree Celsius (113 Degree Fahrenheit) during summer. The mid-land regions are pleasant almost all the year round, although winter nights are cold. The northern mountain region, around an altitude above 3300m has an alpine climate with considerably lower temperature in winter as can be expected.

The altitude from sea-level ranges from 75m to 8,848m. While the southern plains are hot most of the year, temperature decreases gradually towards North as the altitude increases.  The best seasons to visit Nepal are Spring and Autumn. Trekkers can trek from from mid February to early June. In April/ March, the hillsides are covered with blooming rhododendrons in Everest, Annapurna, Manaslu, Dhaulagiri and Langtang trekking regions. The sky is clear in the morning and generally windy with occasional thunder showers in the afternoons.
The rainy or summer season is not suitable for trekking because of the rain. However, Mustang and Dolpo region towards north-west of Dhaulagiri does not receive rain as the cloud flowing from the south is blocked by the range. So, trekking can be organized in this area even in summer. In the rest of the country, the next trekking season starts in mid-September and goes up till late November. During this period, the visibility is good and it does not rain usually. You can get excellent views of landscapes and mountain ranges in this season.

March April and May (Spring): The second premium trekking season in Nepal. The temperature is quite moderates, especially the rhododendrons (National flower of Nepal) are in complete blossom and the mountain views are excellent.
