The local calendar in December is shaped by Christmas market at the Ayuntamiento, 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 December, Valencia has recorded both unusually warm spells and cold incursions across recent decades.
For a typical stay we recommend medium coat and light scarf. 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 December usually offer the best balance in Valencia: moderate crowds, friendlier prices and weather that remains representative of the month.
