Source: TerraClimate 1991–2020 monthly averages. Averages for the area at each point’s elevation (4 km grid, corrected for height). Not a forecast or a report of current trail conditions. Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.
Averages cannot establish current trail conditions. Check recent local reports, the forecast and restrictions before departure. Snow and ice can persist on shaded sections or arrive outside the usual season.
