When to trek in Nepal?
With the highest mountains in world and latitude similar to the state of Florida, Nepal has tremendous variation in climates. The lowland plains are tropical, the midland hills are temperate, and the high mountains have sub-arctic and arctic conditions. For trekkers, the fall and the spring offer the best clarity (mountain views are a big reason why we travel to Nepal) and mild temperatures with the least precipitation. Below are Nepal’s trekking seasons:
In Nepal the months of September to December are peak trekking season. Temperatures are mild, the weather is relatively stable, and the clear air makes for superb mountain views. The high mountains are still cold and lower elevations are still warm but the daytime walking temperatures are the most pleasant overall. Bad weather can hit any time of year but the fall has the most reliable conditions.
The fall season is also when Nepal receives the bulk of trekkers. The most popular trails, such as Everest Base Camp and the Annapurna Circuit, are bustling with trekkers and this is felt from the trails to the tea houses. December is normally dry, stable, and clear, but also cold, especially at higher elevations. By mid-December high elevation trekking becomes treacherous and many tea houses close. During the winter the mountain passes may require technical equipment and experience.
February to April is the second most popular time of the year for trekking in Nepal. The spring temperatures are similar to the fall and the trails are less crowded, but there is slightly more haze and precipitation. This means that in the spring you will need to reach higher elevations for clear mountain views, usually around 10,000 feet and above. Precipitation levels increase as the spring progresses.
