Climate

    Climatic factors are very important in deciding when to visit Nepal. October-November, the start of the dry season, is in many ways the best time of year: the weather is balmy, the air is clean, visibility is perfect, and the country is lush following the monsoon. February-April, the tail end of the dry season is the second-best period: visibility is not so good because of dust, but the weather is warm and many of Nepal's wonderful wild flowers are in bloom. In December and January the climate and visibility are good but it can be chilly: trekkers need to be well prepared for snow, and cheaper hotels in Kathmandu - where heating is nonexistent - can be gloomy in the evening. The rest of the year is fairly unpleasant for travelling: May and early June are generally too hot and dusty for comfort, and the monsoon from mid-June to September obscures the mountains in cloud and turns trails and roads to mud.

Festivals

    Nepal's festive calendar is hectic. Dasain, celebrated nationwide in October, is the most important of all Nepalese celebrations and features the biggest animal sacrifice of the year. Running a close second is Tihar (November), but unlike Daisan, animals are honoured rather than slaughtered. Other festivals celebrated nationally include the water-tinged Holi (March) and Chaitra Daisan (April), which is yet another bad day for animals. Hindu festivals number the Haribodhini Ekadashi (November) and Maha Shivaratri (March), both celebrated in Pashupatinath, the Gai Jatra (August) in Kathmandu and the Krishna Jayanti (August/September) in Patan. Buddhist celebrations are just as thick on the ground, and include Mani Rimdu (November) in Solu Khumbu, Buddha Jayanti (May) in Kathmandu, and Losar (Tibetan New Year) (February) in Swayambhunath, Jawlakhel and highland communities.
