Climate Chart of Bologna, Italy

Climate overview

Temperature

The monthly mean temperature is lowest at 4.4 °C in January and highest at 26.1 °C in July. These are averages for each month, not daytime maximum temperatures, so they describe the broader monthly pattern rather than the range a visitor may experience on a particular day. The unweighted mean across the monthly means is 14.8 °C. It offers a compact overview of the year, but does not represent a day-weighted annual average or the conditions of any single month.

Rain

Mean daily rainfall reaches its highest monthly level, 4.10 mm/day, in May; visitors prioritising lower average rainfall can consider January, when the monthly mean is lowest at 1.46 mm/day. These daily means do not show how often rain falls, and the lower figure is not a guarantee of dry days. Across the calendar-month means, the unweighted mean daily rainfall is 2.22 mm/day. The figures describe daily averages, not monthly rainfall totals, so they cannot by themselves indicate the length or timing of a wet spell.

Sunshine

Mean daily sunshine duration is highest at 12.76 hours/day in June and lowest at 5.16 hours/day in December. These averages can help with planning daylight outdoor activities, but sunshine duration is not the same as day length. The unweighted mean of the monthly daily sunshine averages is 8.86 hours/day. It summarises the calendar-month figures without describing the sunshine on any particular visit day.

Snow

Mean daily snowfall is highest at 5.03 mm/day in February. This is a daily average, not a monthly total; it does not establish how many days have snowfall, how deep snow becomes, or whether snow cover or skiing conditions occur. The unweighted mean across monthly daily snowfall averages is 0.78 mm/day. This summary does not show the distribution of snowfall from day to day.
