If you’re planning a trek in Nepal in September 2026 or 2027, you’ve chosen a time when the Himalayas begin to open up after the monsoon. September marks the start of the autumn trekking season, offering fresh air, lush green landscapes, and fewer crowds compared to October and November.
Whether you dream of the Everest Base Camp, Annapurna Circuit, or Langtang Valley, September is a beautiful month to explore Nepal’s legendary mountain trails.
Why Trek in Nepal in September?
September is a transition month — the rains fade away, the skies clear, and the trails come alive again. You’ll experience:
-
Vibrant green valleys and rice terraces
-
Cleaner air and crystal-clear mountain views after rainfall
-
Fewer trekkers compared to peak months (October–November)
-
Lower prices for flights and lodges in early September
If you start trekking after mid-September, you’ll enjoy ideal weather conditions without heavy rain or crowds.
Weather in Nepal in September
Nepal’s geography ranges from tropical valleys to icy peaks — so weather varies by region and altitude.
Average Conditions:
| Elevation | Daytime | Nighttime | Weather |
|---|---|---|---|
| 1,000–2,000 m (Kathmandu, Pokhara) | 25–30°C | 15–20°C | Warm, humid, occasional rain |
| 2,000–3,500 m (Namche, Ghorepani) | 15–22°C | 5–10°C | Cool, light showers early month |
| 4,000–5,000 m (Lobuche, Manang) | 5–12°C | -2–5°C | Crisp, clear, dry air |
Early September can still bring occasional rainfall, especially in the lower regions. By mid to late September, the weather becomes ideal for trekking — sunny days and blue skies with mild temperatures.
