Your December weather guide
MildWeather in Alcudia in December
Alcudia in December suits a mild-weather break, not a beach holiday built around swimming. Average daytime highs of 15°C make time outdoors appealing with the right layers, but nights fall to around 11°C and the sea is cold at 16°C. For a UK traveller, the draw is milder daytime weather rather than dependable warmth. Go if you are happy to work around showers and spend evenings in a jacket.

Daytime and night-time in December
The typical December day in Alcudia peaks at 15.0°C, but that is an average: the warmest 10% of days reach 17.8°C or more. Days over 25°C are rare. Nights average 10.8°C; one night in ten drops to 8.0°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest December day here reached 20.5°C (2018-12-05) and the coldest night 3.9°C (2020-12-27).

Some rain (4-8 rainy days): about 8 days with 1 mm or more, 47 mm in total. Year to year it varies a lot - the wettest December was 2009 with 108 mm, the driest 2015 with 3 mm. Humidity averages 77%.

Comfortable for walking, too cool for a summer wardrobe
Plan for trousers, layers and a jacket rather than relying on shorts and T-shirts. Warmer December days can reach around 18°C, which gives you some scope for sitting outside, but that is not the everyday expectation. At the colder end, nights can drop to 8°C or below, so bring something warmer for evenings rather than packing only for the daytime average. December sits towards the cool end of Alcudia's year, and the figures give no reason to expect 25°C heat. It suits travellers who prefer being active without hot afternoons; anyone wanting reliable sunbathing weather would be better looking at June, July or August, the stronger months here overall.
Keep outdoor plans flexible and use the daylight
Rain is a practical consideration rather than a reason to rule December out: about 8 days have measurable rain, so a waterproof jacket deserves space in your bag. That does not mean those days are wet throughout, but it does make a rigid outdoor schedule less appealing. There are about 4.3 hours of sunshine within 9.2 hours of daylight, so do not expect clear skies from morning to evening. Give outdoor plans the brightest part of the day and leave room to change them when showers arrive. With limited daylight, an early start makes more sense than saving most of your time outside for late afternoon.
