Trekkers can do summer trekking and winter trekking in Nepal, it is long days trekking and also short days trekking depends up on trekking region area. Because Nepal is quite far south in Latitude (same as Miami), the weather is warmer and winter is much milder at lower elevations. The monsoon is determined by the Bay of Bengal. It is hot during the monsoon with rain almost everyday. During this season, trekkers can do short trekking in Nepal (known as summer trek).It is difficult and uncomfortable, the trails being muddy and infested with leeches in hill region. It usually does not rain for more that one or two days during the entire autumn and the winter season. In the winter, the mountains are covered with snow including some high hills. Mt. Everest itself is a huge black rock during the trekking season, which becomes snow-covered only during the winter. People can do short trekking (known as winter trek).
