Monsoon trekking seasons 2024 (Stay Away): May through August The summer from May through August generally is a poor time to trek in Nepal but if weather good you see the best views during the trek that my guide experience last 20 years so (lower elevation hill treks and the drier Mustang and Dolpo regions can be exceptions to the rule). Significant heat and moisture rise up from the Indian Ocean, bringing hot temperatures, clouds, haze, and rain. This blocks the views, creates messy trails (with leeches), and leads to significant problems with ground transportation. The peak of the Monsoon season occurs in July when the weather begins to taper off into the drier fall period. Moon
