📡 Where this weather comes from & how accurate it is

Source: every value is pulled live from Open-Meteo in your browser when you hit Refresh — nothing is typed in by hand. The forecast uses global weather models (ECMWF / GFS / DWD); the "Last yr" figures come from the ERA5 reanalysis archive for the same villages and dates in 2025. Raw-data links are at the bottom of this page so you can check any number at the source.

How much to trust it: a weather model can only see about 16 days ahead. Anything beyond that shows September climatology (typical averages), clearly tagged "Typical" vs live "🛰️ Forecast." As your dates come inside 16 days, Refresh and the cards flip to real forecast.

Mountain caveat: Himalayan weather is intensely local and changes fast — a model grid-point can't capture a specific valley, and altitude cuts real accuracy. Treat this as planning guidance, not a promise, and always follow your guide and on-the-ground conditions on the day.

Feasibility — cautiously yes, this is the monsoon's tail

Short version: in 2026 the monsoon hasn't withdrawn yet (recent years it hung on to 8–16 Oct), so all of 13–24 Sept is still monsoon-influenced. Trekkable and run by operators, but the first half (Lukla→Dingboche) is wettest/cloudiest, clearing toward Base Camp (~20–21 Sept).

Day to day: rain is mostly afternoon/evening — mornings are clearest, so the Kala Patthar sunrise has a real chance. Peaks hide low down, open up higher.

Biggest risk = Lukla flights, which delay in cloud at both ends. Your operator itinerary has no buffer before the flight home — the purple painted days below are the buffer you should hold.

Buffer days — why they're painted in

  • Your itinerary ends tight. Day 13 (24 Sept) flies Lukla→Kathmandu and Day 14 (25 Sept) is the airport drop — no slack if the Lukla flight is grounded by cloud, which is common in September.
  • The fix: hold 1–2 buffer days (painted purple, 25–26 Sept) in Kathmandu before any international flight home. Operator data shows Lukla cancellations ease after mid-month but never hit zero.
  • If the weather cooperates, buffer days become free time in Kathmandu — not wasted. If it doesn't, they're the difference between making your flight home and missing it.

What recent trekkers & operators report (September)

  • Early Sept (1–10) is wettest with the most Lukla disruption; it improves noticeably from mid-month — your 13 Sept start catches the tail, back half is better.
  • Flights: ~7 full-day Lukla cancellations a year on average, concentrated early September; may route via Ramechhap. Everyone says: buffer days.
  • Late-Sept trekkers are happiest — clearer skies, stable weather, good EBC views — roughly when you reach Base Camp (~20–21 Sept).
  • Crowds far lighter than the October peak; easier teahouses.
  • Typical temps: Lukla ~13°, Namche ~10°, Dingboche ~6°, Gorak Shep ~3° day / −10° night.
  • Tips: waterproofs, early starts for photos, insect repellent low down, flexible flight home.

Sources for the feasibility read

Values are pulled live from Open-Meteo in your browser each time you Refresh — nothing here is hand-entered. A model sees ~16 days out, so later trek days show September climatology (labelled "Typical") until the live forecast reaches them. Mountain weather is local and fast-changing — planning guidance, not a guarantee; follow your guide on the day.
