Climate Chart of Saas-Fee, Switzerland

Climate overview

Temperature

Monthly mean temperatures are lowest in January, at -5.0 °C, and highest in July, at 13.6 °C. This marks a clear shift in the monthly averages over the year, rather than a description of daytime highs or the range a visitor will encounter within a day. The unweighted mean across the monthly mean temperatures is 3.9 °C. It offers a broad annual reference, but does not represent a day-weighted average or imply that temperatures stay close to that figure throughout the year.

Rain

Mean daily rainfall is lowest in both January / February, at 0.02 mm/day. For visitors prioritising lower average rainfall, these months are a conditional option; the figures do not guarantee dry days or show how often rain occurs. The highest monthly mean for daily rainfall is in August, at 5.59 mm/day, so rain preparation is worth considering for plans then. This is a daily mean, not a monthly accumulation, and it cannot describe the timing or duration of individual showers. Across monthly means, the unweighted average of mean daily rainfall is 2.34 mm/day. Use it as a broad summary rather than a forecast for a particular date or a measure of rain frequency.

Snow

Mean daily snowfall is highest in November, at 35.71 mm/day. This is a daily mean amount, not a monthly total, and by itself does not establish the number of snowy days, snow depth, snow cover or skiing conditions. The lowest monthly mean daily snowfall occurs in July, at 0.53 mm/day. The unweighted average across monthly means is 16.60 mm/day per day, which provides a broad summary without indicating how snowfall varies from day to day.

Sunshine

Mean daily sunshine reaches its highest monthly average in July, at 12.29 hours/day. That may help with planning outdoor sightseeing around expected sunshine, but sunshine duration is not the same as day length and does not promise clear skies. The lowest monthly mean daily sunshine is in December, at 5.55 hours/day. The unweighted mean across monthly sunshine averages is 8.81 hours/day per day; these summaries indicate typical duration, not how sunshine is distributed across specific days.
