Comfortable afternoons, but keep a layer handy

April suits travellers who prefer walking and spending time outdoors without much heat. Dalaman's average daytime high is 6.4°C above London's 13.5°C, so afternoons should feel noticeably warmer than at home. Warmer days can reach 23.8°C or more, but days reaching 25°C account for just 4%, so don't pack as though summer has arrived. Light clothing can work during warmer spells, with a jumper or jacket for shade, cooler weather and evenings. The coldest nights can drop to 8°C or below, making long trousers and a proper outer layer sensible if you plan to stay outside after dinner. Keep sun protection handy for bright afternoons.

Allow for rain and treat swimming as optional

Rain is a meaningful part of the April trade-off: there are about 9 rainy days, so keep your plans flexible rather than relying on dry weather throughout. A light waterproof and shoes you can wear comfortably in wet conditions are useful additions to your bag. That doesn't mean writing off outdoor time, but it does mean being ready to move it around when rain arrives. The sea is the firmer limitation. At an average of 17.4°C, it is cold rather than comfortably swimmable, and its usual range of 17°C to 18°C offers little reassurance for anyone who dislikes cold water. Choose April for time outdoors on land, not for long, relaxed swims.
