How these numbers are calculated
  • Powder day — at least 6in of new snow in 24 hours.
  • Bluebird day — sunshine for at least 60% of daylight, following at least 4in of snow over the previous 3 days.
  • Rain day — at least 0.04in of rain (not snow) at this elevation.
  • Skiable day — at least 12in of settled snow on the ground.
  • Snow depth is modelled from Open-Meteo / ERA5 reanalysis at 8,468ft, not measured at the resort. Use it to compare seasons and resorts; use the resort's own report for today's conditions.

November is reliably the snowiest month, averaging 27in and 11 days with fresh snow.

How deep does the snow get at St. Moritz?

Snowfall totals flatter resorts that lose their snow quickly, so the more useful number is how deep the settled base actually gets. At St. Moritz the snowpack peaks at an average of 72in each season. That is well above average, deeper than 85% of 40 resorts we have analysed the same way, against a median peak of 33in.

The base is deepest in April, averaging 57in through the month and topping out around 66in in a typical year.

How many powder days does St. Moritz get?

November has the most, 1.0 on average.

How often does St. Moritz get bluebird days?

St. Moritz averages 15 bluebird days a season — days of sunshine for at least 60% of daylight after 4in or more of fresh snow. That is well above average, more than 75% of 40 resorts we have analysed the same way, against a median of 10.

November is the best month for it, averaging 2.9 bluebird days and 6.0 hours of sunshine a day.

Does it rain at St. Moritz?

At mid-mountain St. Moritz sees an average of 6 days a season with 0.04in or more of rain rather than snow. That is well below average: 5% of the 40 other resorts we have analysed the same way see fewer wet days, against a median of 32.

May is the wettest month of the season, with 4.9 rain days and 0.7in on average.

When is the best time to ski or board St. Moritz, and when does the season end?

St. Moritz typically holds at least 12in of settled snow from around November 5 through to June 6, which works out at roughly 215 days of skiable cover in an average year. 203 of those fall inside the November to May season. On season length that is among the very best we track compared with the 40 other resorts we have analysed the same way.

For the deepest base, go in April; for the most new snow, November; for fresh snow with sunshine, November.
