France · 45.92°N 6.87°E · 30-year monthly averages, judged against the Warm preset (highs 19–28 °C66–82 °F, dry or showers)
No month in Chamonix fits the Warm preset (highs 19–28 °C66–82 °F, dry or showers): it is too cold. The table below shows which holiday types do fit.
Rain falls all year, 96–152 mm3.8–6.0 in a month, so there is no dry season. July is the driest month and November the wettest. August is the hottest month (highs of 13 °C55 °F) and January the coldest (-3 °C27 °F); nights are below freezing from October to May.
The figures are 30-year monthly averages (WorldClim 2.1 monthly normals 1970–2000) for the 0.25° grid cell at 45.92, 6.87. This is a climate guide, not a forecast.
Pick the weather you like. Every month is then judged against it: temperature above the month names, rain below.

Reading the chart. Gold means good: the month fits what you picked. Any other colour shows the reason it does not. The temperature bar can be too cold or too hot; the rain bar can be too dry, too rainy or monsoon. A faded gold bar means that half fits but the other half does not. A gold month name means both halves fit.
What the verdicts mean. Temperature is the month's average daily high (the afternoon), judged against the preset's band (highs 19–28 °C66–82 °F for Warm). Rain is judged by each month's class within Chamonix's own year, not by raw millimetres: dry under 60 mm2.4 in, showers 60–100 mm2.4–3.9 in, rainy from 100 mm3.9 in and at least 35 % of the wettest month. Too rainy is a rainy-season month that the preset does not allow. Monsoon is the heaviest kind of rainy season: 180 mm7.1 in or more (120 mm4.7 in near the yearly peak) in a climate where the wettest month has at least three times the rain of the driest. Every monsoon month is also a rainy-season month; the label says which kind. Full rules on the method page.
