Weather in Salou in December

Salou in December suits a cool-weather break, not a beach holiday. Average highs of 13.4°C make daytime walks more appealing than sitting out in swimwear, while nights fall to 6.4°C and call for a proper jacket. The sea averages 15.2°C, so swimming is a cold prospect. For a UK traveller, the appeal is milder afternoons and some sunshine rather than reliable warmth. Go if you enjoy being outdoors in layers; choose another month if heat matters.

Milder than London, but pack for winter

December afternoons in Salou average 5.7°C warmer than London's, a useful improvement without turning the trip into a warm-weather holiday. The warmest days can reach 16.7°C or more, making a walk or a spell sitting outside more comfortable, but that is not the everyday expectation. Plan around cool conditions and bring layers you can adjust as the day changes. A jumper and jacket will be more useful than a suitcase built around summer clothes. Evenings need particular thought: the coldest nights fall to 2.4°C or below, so do not judge what to wear after dark by how pleasant it felt earlier. December suits travellers happy to keep moving rather than lounge outdoors.

Make the most of daylight, with a rain backup

There is enough sunshine to make outdoor time worthwhile, but not enough to assume every day will be bright. December averages about 4.7 hours of sunshine within 9.1 hours of daylight, so give daytime walks priority and leave flexible plans for the evening. Rain falls on about 5 days during the month, making a light waterproof a sensible addition rather than a reason to rule the trip out. Keep your plans easy to change if a wet spell arrives. The best fit is a break where walking and time indoors are equally welcome. If your enjoyment depends on spending most of the day outside in warmth, December asks for too much compromise.
