Climate Chart of Lausanne, Switzerland

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

Climate overview

Temperature

January has the lowest monthly mean temperature, at 2.8 °C; this describes the month's average, not the coldest nights or daytime highs. At the warmer end of the annual pattern, July has the highest monthly mean, 20.7 °C. Across the calendar-month means, the unweighted mean is 11.4 °C, a broad summary that does not represent every day equally.

Rain

Mean daily rainfall reaches its highest monthly value in May, at 4.63 mm/day. This is a daily average for that month, not a monthly rainfall total, and it does not indicate how often rain falls. February records the lowest monthly mean daily rainfall, 2.25 mm/day. The unweighted mean of the monthly values is 3.53 mm/day; neither figure guarantees dry weather on a particular day.

Snow

Mean daily snowfall is highest in January, at 8.54 mm/day. This records an average amount, not the number of snowy days, snow depth or persistence of snow cover. Across the monthly means, the unweighted average daily snowfall is 2.77 mm/day. It should not be read as a measure of skiing conditions or accumulated snowfall.

Sunshine

Mean daily sunshine is highest in July, at 11.79 hours/day, and lowest in December, at 4.39 hours/day. These are average sunshine durations, not measures of daylight length or a promise of clear skies. The unweighted mean across the monthly sunshine values is 8.28 hours/day per day, a useful overall reference that does not capture day-to-day variation.

Best Travel Time Guide for Lausanne, Switzerland: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, January is the relevant reference, with a monthly mean temperature of 2.8 °C; pack for variable conditions, since this average does not describe daily highs or nighttime lows. If lower average rainfall is your priority, February is the conditional option, with mean daily rainfall of 2.25 mm/day. It does not guarantee rain-free days, so a light waterproof layer remains practical; for rain preparation, note that the highest monthly mean daily rainfall is in May, at 4.63 mm/day.

For planning outdoor sightseeing around average sunshine, July has the highest mean daily sunshine duration, 11.79 hours/day, while December has the lowest, 4.39 hours/day. Sunshine averages can help with broad planning but are not day-length figures and cannot predict the conditions on a specific day. The recorded snowfall peak is January, with mean daily snowfall of 8.54 mm/day. This alone cannot tell visitors how many days will have snow, whether snow will lie on the ground, or whether winter activities will be suitable.
