Mild afternoons, chilly evenings

December is among Valencia's coolest months, so pack for changing temperatures rather than treating it as a summer destination. A light jumper and jacket give you flexibility during the day; keep a warmer layer for evenings, especially if you plan to sit outside. The warmest days can reach 18.9°C or more, which may feel pleasantly mild, but that is not the everyday expectation. At the colder end, nights can fall to 4.2°C or below. Make the middle of the day your main window for longer walks, and do not rely on midday warmth lasting after dark. This is a better fit for travellers who prefer exploring without strong heat.

Plan for daylight, not beach weather

With 9.2 hours of daylight, it pays to put outdoor plans ahead of indoor time rather than leave them until late afternoon. About 5 rainy days means wet weather is a possibility, but it need not define the trip. Bring a compact umbrella or waterproof jacket and keep your plans flexible if rain arrives. The sea is the clearer limitation: at 15.6°C, it is cold, not a comfortable setting for a leisurely swim. Time by the water is better approached as a walk with layers on than a beach day. December works if your priority is being outdoors in mild weather and you can accept chilly evenings and occasional rain.
