HotWeather in Belek in May
May is a good time for Belek if you want warm days without needing reliably hot weather or a warm sea. Average afternoon highs are around 25°C, nights fall to around 15°C, and the sea averages 21°C, so swimming can feel bracing. For a UK traveller, the appeal is comfortable warmth for time outdoors. The catch is that rain remains possible, evenings need a layer, and some days turn much hotter than the average.

Nights average 14.8°C; one night in ten drops to 11.9°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest May day here reached 39.8°C (2020-05-18) and the coldest night 8.5°C (1993-05-03).

Warm days, with occasional stronger heat
Belek in May suits travellers who want to spend much of the day outside but do not need constant heat. Days reach 25°C about 54% of the time, while 11% reach 30°C, so pack for warmth without assuming every afternoon will be hot. Lightweight clothes are sensible for daytime, with shade breaks when the midday heat builds. The cooler end of the night-time range matters too: the coldest nights fall to around 12°C or below. A jumper or light jacket gives you more flexibility after sunset than a suitcase packed only for summer heat.
Beach weather does not mean a warm sea
The main compromise in May is the water. The sea averages 21.1°C, with a year-to-year range of 20°C to 22°C, which puts it in bracing rather than reliably warm territory. If you are happy with a cool dip, that may be perfectly acceptable; if long, relaxed swims are the point of the holiday, May is less convincing. Sunshine averages about 9.7 hours a day, so there is plenty of scope for sitting out, but sunshine and sea warmth are different things. Pack swimwear alongside something dry to put on afterwards, and judge swimming comfort separately from the afternoon air temperature.
Mostly outdoor plans, with room for rain
Rain is a reason to keep plans flexible, not to rule May out. There are about 5 rainy days during the month, so a completely dry stay is not something to bank on. A light waterproof is useful, and it makes sense to leave outdoor plans movable rather than tying everything to a particular day. Around 14.0 hours of daylight gives you room to shift activities around the weather. May is among Belek's best-rated months alongside June and September, making it a sensible choice if you value warm afternoons and generous sunshine more than dependable sea-swimming comfort or guaranteed dry weather.
