When Exactly to Start Your Autumn 2026 Nepal Trek: A Week-by-Week Guide

Ask 'when should I start my autumn Nepal trek?' and most advice just says 'October.' That isn't specific enough for 2026, because Nepal's two biggest festivals — Dashain (Oct 11-25) and Tihar (Nov 7-11) — fall squarely inside the autumn trekking window and change flights, buses, guide availability and trail crowds week by week. Here is an honest, week-by-week read on when to actually start.

Key facts — Nepal festival dates, 2026

Dashain: Ghatasthapana Oct 11 → Vijaya Dashami (main Tika day) Oct 21 → Kojagrat Purnima (close) Oct 25.
Tihar: Kaag Tihar Nov 7 → Bhai Tika (final day) Nov 11.
Both festivals sit inside Nepal's clearest-sky, most reliable-flight window (Oct-Nov) — the logistics issue is entirely about people traveling home, not weather.
Domestic flights and long-distance buses are typically booked out weeks in advance around the main Tika days as Nepalis travel to their home villages.

Why the dates matter more than the month

October and November are Nepal's best trekking weather, full stop — post-monsoon skies, stable Lukla flights, dry trails. That is exactly why airlines, buses and teahouse staff are stretched two ways at once: trekking season and the country's biggest homecoming. Around Vijaya Dashami (Oct 21) especially, many Nepalis — including guides, porters and lodge staff — travel to be with family, similar to a Christmas staffing crunch elsewhere. It doesn't shut the trails down, but it is the one week of the season where you should expect thinner staffing and tighter transport, not the clear, quiet trekking you pictured.

Autumn 2026 start-week planner
Week starting	What's happening	Verdict
Sep 28	Monsoon tail-end, skies still clearing	Caution — weather inconsistent
Oct 5	Dry weather arriving, Dashain travel not yet peaked	Good
Oct 12	Dashain underway (Ghatasthapana Oct 11); flights/buses filling	Caution — book early
Oct 19	Vijaya Dashami Oct 21 — guides and staff traveling home	Avoid starting this week if avoidable
Oct 26	Post-Tika, clearest skies, staffing back to normal	Best window of the season
Nov 2	Peak clear-sky trekking, trails at their busiest	Good, but crowded — book teahouses ahead
Nov 9	Tihar underway (Nov 7-11); shorter travel crunch	Caution — book early
Nov 16	Post-Tihar, still clear, trails thinning out	Best value window
Nov 23	Cold deepening; early snow risk on high passes	Caution for high-altitude routes
Nov 30	Winter approaching; some high teahouses closing	Avoid EBC and high Annapurna; fine for lower treks

2Sweet-spot windows: late October and mid-to-late November

The two best windows, and why they work

The strongest single week to start a 2026 autumn trek is the week of October 26 — Dashain is fully over, staff and transport are back to normal, and you still get October's legendary clarity without the pre-Tika rush. The second-best window is mid-to-late November, after Tihar wraps on the 11th: skies are still clear, trails are visibly thinner than the October peak, and — per the Annapurna Conservation Area's own 2025 arrival data — this is genuinely a quieter month than the April and October crowd peaks. The trade-off by late November is cold: expect teahouse nights well below freezing above 4,000m, and build in buffer days in case an early-season snowfall closes a high pass like Thorong La for a day.

What this means for trekkers

Don't book a start date inside Oct 17-23 unless you have no choice — that is the week transport and staffing are tightest around Vijaya Dashami. If your dates are flexible, aim for Oct 26-Nov 5 for the best mix of clear weather and normal logistics, or push to mid-November for a quieter trail at the cost of colder nights. Either way, lock in flights and your trekking permit slot 6-8 weeks ahead if any part of your trip overlaps Oct 11-25 or Nov 7-11 — that is when domestic seats disappear fastest.

What this looks like for specific treks

Everest Base Camp (12-14 days): Start Oct 26-Nov 5 to land at Base Camp with October's clarity intact and normal Lukla flight staffing.
Annapurna Base Camp or Poon Hill (short treks): Mid-November works well — lower altitude means the cold trade-off is smaller, and trails are noticeably quieter than October.
Anything crossing a high pass (Thorong La, Larkya La): Don't start after mid-November — build in a weather buffer day, since early snow becomes a real risk from late November.
