    • Weather: Post-monsoon, the weather stabilizes, offering clear blue skies and dry trails. Daytime temperatures in the mountains are pleasant, averaging 10-15°C (50-59°F), while nights can drop to freezing in high altitudes.

    • Weather: Temperatures rise during this period, ranging from 15-20°C (59-68°F) in the lower regions. Higher altitudes still have cool temperatures, but the weather remains stable. Skies are generally clear, although occasional cloud cover can occur in the late afternoons.

  3. Winter (December to February) – Challenging Yet Rewarding
    • Overview: Winter trekking in Nepal is possible, but conditions are much colder and snow often blocks higher-altitude trails. However, it offers solitude and snow-covered landscapes for trekkers who prefer less crowded routes.
    • Weather: Temperatures in high altitudes can fall below -10°C (14°F), with daytime temperatures around 5-10°C (41-50°F). Lower elevations experience milder conditions, but the nights remain cold.

  4. Monsoon (June to August) – Less Favorable, but Still Possible
    • Overview: Monsoon season brings heavy rainfall, which makes most trails muddy and leech-infested. Landslides are common, and clouds often obscure mountain views. However, this is the best time to trek in rain-shadow areas like Upper Mustang and Dolpo.
    • Weather: High humidity and temperatures averaging 20-25°C (68-77°F) in lower elevations. Rain showers are frequent and often last for several hours.
