Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

Weather read at Jackson, the town of the valley, 14 km from the airport (JAC): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

September: about usual. Busiest from June to August; quietest in March, April, May, November and December.

Public holidays in September

Holidays crowd a place out and push fares up around them; they count toward the crowd score above.

What to pack

  • A proper coat, hat and gloves: nights average 5°C.

  • Sun protection: about 11 hours of sunshine a day.

Each line is a threshold over the ten-year figures above, not advice from anywhere else.
