The climate in Nepal varies from subtropical in the lowlands to a cold high-altitude climate in the mountains.October - November (autumn) and Mid February - May (spring) are considered the best times of the year to travel to Nepal. The monsoon will have just ended, and clear skies with optimal temperature will prevail. Between the winter months of December and mid-February the tourist flow will decrease a little. It catches up once again between mid-February and May. From mid-June to early October, it's the monsoon, during which it rains almost everyday and most of the Himalayas are hidden behind the clouds.During the monsoon some parts of the country can not be reached due to flooding. The mountain paths are generally slippery during this rainy season and often people have to wade through rivers and rice fields.
