Climate Chart of Zurich, Switzerland

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

Climate overview

Temperature

Monthly mean temperatures are lowest in January, at 1.7 °C, and highest in July, at 20.5 °C. These are monthly averages, not daytime maximum temperatures, so they describe the broad temperature profile rather than the range visitors might experience within a day. Across the calendar-month means, the unweighted mean is 10.8 °C. It is a summary of the monthly means, not a day-weighted annual average, and does not specify conditions on any particular visit.

Rain

Mean daily rainfall reaches its highest monthly level in May, at 4.28 mm/day. This is a daily mean, not a monthly rainfall total, and it does not tell you how often rain falls or whether any individual day will be wet. The lowest mean daily rainfall is shared by February / March, at 1.90 mm/day. The unweighted mean across calendar-month means is 3.00 mm/day; neither figure guarantees dry weather or measures the frequency of rainy days.

Sunshine

Mean daily sunshine duration is highest in June, at 11.72 hours/day, and lowest in December, at 4.22 hours/day. These averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length. The unweighted mean across calendar-month sunshine averages is 8.03 hours/day per day. It summarizes the monthly means and cannot establish how much sunshine a particular day will bring.

Snow

Mean daily snowfall reaches its highest monthly level in January, at 6.66 mm/day; the unweighted mean across calendar-month means is 1.86 mm/day. These are snowfall averages, not monthly totals, and they do not establish the number of snowy days, snow depth, snow cover or skiing conditions.

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

For visitors prioritising cooler monthly mean conditions, January is the relevant reference point, with a monthly mean of 1.7 °C; this does not describe daytime highs or guarantee a particular day's weather. If lower average rainfall is a priority, February / March is the conditional option, with mean daily rainfall of 1.90 mm/day. For rain preparation, note that the highest mean daily rainfall occurs in May, at 4.28 mm/day; neither average quantifies rain frequency, so flexible plans and suitable rain protection remain sensible.

For outdoor sightseeing planned around average sunshine, June has the highest mean daily sunshine duration, at 11.72 hours/day, while December has the lowest, at 4.22 hours/day. These figures may inform daylight outdoor planning, but sunshine duration is not day length and does not predict conditions on a specific date. The snowfall mean for January is 6.66 mm/day per day, but a mean daily amount does not reveal how many days have snow or whether snow will be present during a visit. Treat it as climate context, not a forecast of snow cover or activity conditions.
