September is a breath of fresh mountain air — quite literally. After weeks of relentless monsoon rains, the skies begin to clear, the trails dry up, and the lush hillsides burst with life. If you’re considering the Annapurna Base Camp (ABC) Trek in September, you’ve picked a beautiful turning point — a time when the trails slowly awaken from their slumber, and the mountains begin to show their faces again.
While not as crisp as October, September offers an early bird advantage. Fewer crowds, greener hills, and an undeniable freshness that only comes after weeks of cleansing monsoon rain.
So, What’s It Like Trekking ABC in September?
It’s a month of transition. Early September can still feel monsoonal — think warm, humid, with lingering afternoon showers. But as the month rolls on, especially past mid-September, the skies open up, visibility improves, and the mighty Machapuchare and Annapurna Massif begin their reentry into the spotlight.
You’ll still see clouds. You’ll still dodge puddles. But you’ll also experience that first gasp when the clouds part at dawn and the entire mountain range glows gold.
Weather in September
| Location | Day Temp | Night Temp | Condition |
|---|---|---|---|
| Pokhara | 26–30°C | 18–22°C | Warm and humid, fewer showers mid-month |
| Chhomrong Area | 20–24°C | 15–18°C | Partly cloudy, occasional rain |
| Annapurna Base Camp (4,130 m) | 6–12°C | 0–4°C | Chilly mornings, possible snowfall late month |
Trek tip: Start early each day. Mornings are usually clearer, while afternoons may still bring clouds and drizzles — especially in the first half of the month.
Why Trek ABC in September?
✅ Post-monsoon freshness — the forests, fields, and flowers are alive and vibrant
✅ Gradual clearing of skies — perfect for photography lovers chasing early views
✅ Still off-peak — quieter trails and more flexible accommodation
✅ Better trail conditions than peak monsoon months
✅ Warmer than October — less worry about freezing nights
The Not-So-Great Bits
❌ Lingering rain in early September
❌ Muddy sections in lower elevations
❌ Some leeches — especially below Bamboo and near rivers
❌ Unpredictable skies — you might not get those postcard views every day
But for the most part, these are mild trade-offs. The weather only gets better as the month moves forward.
Trailhead Access in September
This is another perk of trekking in September — road access improves daily as the rain weakens and landslides are cleared.
| Route | Notes |
|---|---|
| Kathmandu to Pokhara | Daily tourist buses (7–9 hrs) or 25-min flight |
| Pokhara to Ghandruk or Siwai | Jeep rides resume after monsoon damage is fixed — expect some bumps |
| Trek begins | From Siwai or Ghandruk, depending on road and jeep conditions |
Pro Tip: Check trail updates with locals in Pokhara — they’ll know if a section is closed or rerouted.
Packing List for ABC in September
You’re dealing with a changing climate — mix summer and monsoon gear with a dash of light winter prep.
Essentials:
-
Rain jacket or poncho (especially early Sept)
-
Waterproof boots or trekking shoes with good grip
-
Light fleece and insulated jacket for ABC
-
Trekking poles (muddy sections = slippery!)

Sunscreen + sunglasses (UV gets strong post-rain)

Leech protection (just in case): salt or Dettol spray
-
Quick-dry towels and extra socks
Views in September: Will You See the Mountains?
Yes — and maybe some of the best surprises.
While early September can feel uncertain, late September often surprises trekkers with jaw-dropping morning views, cloud inversions, and golden hour perfection. Even if the days are partly cloudy, ABC and Machapuchare Base Camp often offer glimpses of the giants between 6 and 9 a.m.
