When to go? Seasons, climate, festivities
March to MayHiking Nepal in the spring comes with the same risks and rewards of any springtime activity: beautiful, blooming flowers and mild temperatures, but also the risk for the spontaneous chilly day early on. You can expect mild temperatures are the norm in lower elevation (800-2000m) regions in the spring, making trekking in areas like lower Annapurna very pleasant. Locations with elevations above 4000m usually have moderate temperatures, making way for cloudless skies and warm- weather trekking conditions.
Spring is considered one of the best seasons to trek and climb in Nepal, not only because of the weather but because of the gorgeous growing landscape.
June to AugustMonsoon season runs from late May until mid-September, so your standard summer vacation may not apply in Nepal. Trekking or climbing during this time of year is dangerous and discouraged. Monsoon season in Nepal also means warm, humid conditions that would make for uncomfortable climbing weather. The lower elevations tend to get completely saturated with rain, mud, and even leeches. But this by no means implies summer is totally off limits for the region. While Nepal likely won’t be your destination of choice, these months are ideal for exploring the Ladakh region in India. Because of its elevation on the Tibetan plateau, this time of year is mostly dry and sunny, not to mention surrounded by incredible scenery.
September to NovemberAutumn is considered the best trekking season in Nepal. While springtime runs the risk of some cooler afternoons, after monsoon season clears, you can almost guarantee sunshine and cloudless skies all day long. Autumn in Nepal means moderate temperatures and pretty excellent trekking and climbing conditions, topped off by incredible views made possible once the dust and pollution are cleared from the atmosphere by the monsoon. But of course, you have to be careful: start too early and you could still run into monsoon trouble. You are usually safe starting around the middle of September, once the weather has fully settled. On the opposite end, beware of treks set too late in the year. Once you hit December, the temperatures can plummet.
December to FebruaryFor the majority of travelers, those December temperatures could mean a miserable trek in Nepal. Winter climate ranges from 9 to 12 degrees Celsius during today, to below zero at night. If you can survive the polar climate, you can certainly avoid the crowds, since most climbers explore during the more temperate times of the year. The Everest region, in particular, is far less crowded than in the Autumn, for instance. But because of morning fog, high passes in the Everest region, such as Kongma La, Cho La, and Renjo La are usually closed from November until March.
