August brings 22°C daytime highs, 30mm of precipitation across about 5 wet days and 13.9 hours of daylight — best for hiking, cycling and reliable sunshine. The strongest run of the year is June to August. November is the quietest month: quiet and local, and still good for autumn colour, low-angle light and quiet and local.

November gets roughly 160% more precipitation than August — 78mm against 30mm. That difference, more than temperature, is what changes how a day here feels.
Daytime highs only move 19°C across the whole year (4–23°C), so timing matters far less here than rainfall does.
June gives you 15.6 hours of daylight against just 8.4 in December — a 7-hour difference in how much you can actually fit into a day.
January is the driest month at 18mm across roughly 4 wet days, while November peaks at 78mm.
January sit at or below freezing, so the precipitation shown for those months falls mainly as snow rather than rain — the millimetre figures are water equivalent, not puddles.
July is almost as good as August, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Crans-Montana changes character completely through the year — August and November are effectively two different destinations. Pick the month that matches what you want to do, not the highest-rated one.
Ratings compare months within Crans-Montana, not against destinations worldwide: five stars means the best time to be here, not that Crans-Montana beats anywhere else. Tags describe what the conditions actually suit.

Each month in Crans-Montana is described from long-run climate normals and then rated relative to the other eleven months in the same city. A five-star January in a cold destination means January is one of the best times to be there — not that it beats a Mediterranean summer.
| Factor | Weight | What it measures |
|---|---|---|
| Temperature | Described | Average daytime high and overnight low for the month, shown as measured rather than judged. |
| Precipitation | Described | Monthly millimetres and wet-day count, labelled as snow or rain/snow where temperatures make that the likely phase. |
| Sunshine & daylight | Described | Average daily sunshine hours and astronomical daylight length at mid-month, from the city’s latitude. |
| “Best for” tags | Derived | Applied only when the conditions genuinely support the activity — snow depth-friendly cold for skiing, 13–24°C and low rain risk for hiking, dark evenings at high latitude for aurora. A month with few strong use cases gets fewer tags rather than padded ones. |
| Star rating | Relative | Ranks the month against the other eleven months in the same city. Never a comparison between cities. |
Figures are long-run climate averages, not a forecast for a specific year. This city has no published month-by-month normals on file, so monthly temperatures are interpolated from its summer and winter averages and rainfall is modelled from rain-day frequency.
