Official records (AEMET). Secondary stations may have more extreme readings.
In March, Barcelona typically shows spring transition with 16-18 °C. The average high temperature is around 17°C and the average low around 7°C, with monthly rainfall of 44 mm spread over roughly 6 rain days and about 193 hours of sunshine. Average relative humidity stands at 71% and wind speed averages 13 km/h.
The local calendar in March is shaped by first family Diada and Carnaval, so checking the forecast a few days in advance is worth it before any outdoor activity. Averages give a general picture but extreme events can vary widely: in March, Barcelona has recorded both unusually warm spells and cold incursions across recent decades.
For a typical stay we recommend mid-season jacket. UV protection is sensible on sunny days, even in a mild winter month, and a closed-toe waterproof shoe helps on damp days. For multi-day trips bring thin layers that you can combine through the day.
The first two weeks of March usually offer the best balance in Barcelona: moderate crowds, friendlier prices and weather that remains representative of the month. Late March starts showing features of the transition to the next month. Use our custom historical lookup to check the actual values for the exact year you plan to travel.
