Climate Chart of Annecy, France

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

The monthly mean temperature is lowest in January, at 1.9 °C, and highest in July, at 21.3 °C. These are monthly averages rather than daytime maximum temperatures, so they describe the broad temperature pattern without indicating how warm or cold a particular day may feel. The unweighted mean across the monthly temperature means is 11.2 °C. It summarizes the calendar-month averages; it is not a day-weighted annual average or a forecast for any individual visit.

Rain

Mean daily rainfall is highest in May, at 4.61 mm/day, and lowest in February, at 2.44 mm/day. The figures are daily means, not monthly rainfall totals, and the lower average does not guarantee dry days or show how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 3.21 mm/day. This offers a broad reference for the year, but it cannot describe the timing or intensity of rainfall on particular dates.

Sunshine

Mean daily sunshine reaches its highest value in July, at 12.21 hours/day, and its lowest in December, at 4.88 hours/day. These are averages of sunshine duration, not measures of day length, and actual sunshine can differ from the monthly pattern. The unweighted mean across the monthly sunshine averages is 8.59 hours/day per day. It provides a year-wide reference rather than a promise of sunshine on any given day.

Snow

Mean daily snowfall is highest in January, at 8.27 mm/day; the unweighted mean across monthly snowfall means is 2.33 mm/day. These daily averages do not establish how many days receive snow, its depth, whether snow cover persists, or whether conditions suit skiing.

Best Travel Time Guide for Annecy, France: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, February is the criterion-based option, with mean daily rainfall of 2.44 mm/day; it is not a guarantee of dry weather. If planning around the higher-rainfall average, prepare for possible wet conditions in May, when the mean is 4.61 mm/day. These figures are daily means, not monthly totals or measures of rain frequency. Those who prefer cooler monthly averages can use January as a reference, when the monthly mean temperature is 1.9 °C; this is not a daytime maximum or a prediction for specific dates. For outdoor sightseeing that prioritises average sunshine duration, July records 12.21 hours/day per day, while December records 4.88 hours/day. Sunshine duration is not day length, and neither average ensures particular conditions during a trip.

Snowfall averages may help set expectations, but the highest mean daily snowfall is 8.27 mm/day in January; this does not tell visitors how many snowy days to expect or establish snow depth, lasting cover, or skiing conditions. Check current forecasts close to travel dates and pack for the conditions expected during the visit.
