June brings 16°C daytime highs, 30mm of precipitation across about 5 wet days and 18.6 hours of daylight — best for hiking, cycling and reliable sunshine. The strongest run of the year is May to July. November is the quietest month: cold and snow-focused, and still good for snow, skiing and aurora & dark skies.
Long-run climate normals for Geilo. Month ratings compare months within Geilo only — they are not a ranking of Geilo against other destinations, and they are not a forecast for a specific year.
Conditions on this page are recalculated from the latest forecast every time it is opened, for the current date in the location's own time zone. Showing .

November gets roughly 80% more precipitation than June — 54mm against 30mm. That difference, more than temperature, is what changes how a day here feels.
Geilo swings 21°C between July (17°C) and January (-4°C) — the month you pick changes what you pack more than where you go.
June gives you 18.6 hours of daylight against just 5.4 in December — a 13-hour difference in how much you can actually fit into a day.
February is the driest month at 9mm across roughly 2 wet days, while October peaks at 90mm.
January–December 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.
May is almost as good as June, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Geilo changes character completely through the year — June 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 Geilo, not against destinations worldwide: five stars means the best time to be here, not that Geilo beats anywhere else. Tags describe what the conditions actually suit.

Each month in Geilo 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.
