Climate Chart of Barcelona, Spain

Climate overview

Temperature

Monthly mean temperature is lowest at 8.8 °C in January, and reaches its yearly peak of 25.1 °C in July. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the range a visitor might experience within a day. The unweighted mean of the monthly means is 16.6 °C; it summarizes the monthly figures without weighting them by the number of days in each month.

Rain

Mean daily rainfall is lowest at 0.84 mm/day in July, a useful reference for visitors prioritising lower average rainfall. The highest monthly mean is 3.05 mm/day per day in October, so rain preparation is worth considering then. These are daily averages for the named months, not monthly rainfall totals; they do not show how often rain falls or guarantee dry or wet days. The unweighted mean across monthly means is 1.76 mm/day per day.

Sunshine

Mean daily sunshine reaches 13.30 hours/day in July and is lowest at 7.12 hours/day in December. These figures can help with planning outdoor sightseeing around average sunshine duration, but sunshine hours are not the same as day length and do not promise clear conditions on a particular day. The unweighted mean of the monthly sunshine figures is 9.87 hours/day per day.

Snow

The highest monthly mean daily snowfall is 0.31 mm/day in February, while the unweighted mean across monthly snowfall means is 0.03 mm/day per day. These are small average amounts, but they do not establish how many days saw snowfall, snow depth or snow cover, and cannot indicate whether skiing conditions are available.
