The local calendar in September is shaped by Tomatina nearby and back to school, 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 September, Valencia has recorded both unusually warm spells and cold incursions across recent decades.
For a typical stay we recommend sturdy umbrella and short sleeves. 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 September usually offer the best balance in Valencia: moderate crowds, friendlier prices and weather that remains representative of the month.
