Your March weather guide
MildWeather in Dalaman in March
Dalaman in March suits a mild-weather break, not a holiday built around heat and swimming. Average afternoons reach about 17°C, nights fall to around 8°C, and the sea is cold at 16.7°C. For a UK traveller, the appeal is spending time outdoors without summer heat; the catch is rain and chilly evenings. Go if you are happy wearing layers and changing plans around showers, rather than expecting reliable beach weather.

Daytime and night-time in March

Nights average 8.2°C; one night in ten drops to 5.3°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest March day here reached 26.2°C (2001-03-31) and the coldest night 1.2°C (2012-03-01).

Is March a good time to visit Dalaman?
March is not the strongest month here: mild days and frequent rain. The best months for Dalaman on our scoring are September, June, October; months averaging 25°C or more: Jun, Jul, Aug, Sep, Oct.
Mild afternoons, but leave room for rain
March can be comfortable for walking and spending time outside, especially when the sun is out. There are about 6.7 hours of sunshine within 11.7 hours of daylight, so useful outdoor time is part of the appeal. Rain is a real consideration, though, with about 9 rainy days during the month. Keep your plans flexible rather than committing every day to being outdoors. A waterproof jacket and shoes that cope with wet ground are sensible packing choices. The warmer days can reach 20°C or more, but treat that as a bonus rather than the temperature to expect throughout your stay.
Cold water and evenings that need a jacket
The sea is the clearest reason to reconsider March if swimming is central to your holiday. At 16.7°C, it is cold rather than comfortably refreshing, so do not plan around long, relaxed swims. Sitting by the water is a different proposition, but take a layer rather than relying on swimwear alone. Evenings also need proper thought: the average night low is 8.2°C, and the coldest nights can fall to 5.3°C or lower. Pack a jumper and a jacket for being outside after dark. March works better for travellers who prefer mild daytime conditions and do not mind wrapping up once the warmth fades.
