Warm enough for summer clothes, but not reliably hot

The daytime average makes May comfortable for being outdoors without planning everything around strong heat. Light clothes should work on warmer afternoons, while a jumper or light jacket earns its place once the sun goes down. Days reaching 25°C account for 15% of the month, so proper warmth is possible but should not be the basis of your booking. At the cooler end, the coldest 10% of nights reach 13.2°C or below. If your priority is eating outside in light clothing well into the evening, May carries more of a compromise than the daytime temperature suggests.

Plenty of daylight, with room for rain

Around 8 hours of sunshine within 14.2 hours of daylight gives you plenty of scope to spend time outside. It does not mean clear skies all day, though, and about 6 rainy days makes a light waterproof a sensible addition to your bag. Keep outdoor plans flexible rather than treating any particular day as guaranteed beach weather. The balance is still useful for a holiday built around fresh air and gentle warmth: you have long days to work with, but should be comfortable changing plans when rain arrives. May suits that approach better than a trip whose success depends on constant sun.

The sea is the main compromise

The sea averages 18.1°C, so expect an invigorating dip rather than water that feels comfortably warm. Its year-to-year range of 17°C to 19°C means a warmer May does not necessarily remove that chill. If swimming is optional, this may be a manageable trade-off for the mild air temperatures. If long, leisurely swims are central to your holiday, May is harder to recommend. June, July and August are the stronger months overall for Alcudia, though May remains a reasonable choice for travellers who value warmth without needing peak heat. Bring something dry to put on after getting out.
