The best months to visit Annapurna Sanctuary are mid-September to November and March to May. The weather is sunny and mild, and the sights are spectacular. At most heights, daytime temperatures are generally pleasant for walking, the sky is clear most of the time, and rain and snow are only seen on rare occasions. If you want to get away from the crowds and spend some time alone with nature, it is recommended you trekking there in December, January, or March. However, most visitors may find the weather in the winter to be oppressive. Summer or Monsoon trekking (June to August) will be hampered by rain, however a skilled botanist may find the summer journey beneficial.
