Between 1991 and 2020 the hottest August day here reached 31.9°C (2017-08-13) and the coldest night 13.8°C (2009-08-13).

Is August a good time to visit Side?
It is a reasonable choice: hot days but expect showers. The best months for Side on our scoring are July, August, June; months averaging 25°C or more: Jul, Aug.
Warm days, with humidity the main catch
Average daytime highs of 25.5°C make August a good fit if you want warmth without routinely facing very high temperatures. Days reach 30°C only 2% of the time, so that level of heat is possible rather than typical. Humidity of 83% is the bigger comfort issue: expect muggy conditions and leave room for shade and breaks around midday. Loose, breathable clothing makes sense, especially if you plan to spend much of the day outside. Nights average 20°C, so evenings generally call for light clothes, though a thin extra layer is sensible for cooler spells. August suits travellers comfortable with humid warmth more than those seeking crisp, cool evenings.
Good sea temperatures, but keep plans flexible
The sea averages 25.5°C, making swimming a strong reason to choose August. Its year-to-year range of 25°C to 26°C also suggests little variation in how warm the water feels. The weather above it is less dependable: about 13 days bring measurable rain, so do not plan around an entirely dry holiday. That does not tell you how long each wet spell lasts, and it would be unwise to assume rain always clears quickly. There are about 7.5 hours of sunshine a day on average, leaving a useful balance of swimming opportunities and brighter weather. Pack a light waterproof and keep outdoor plans flexible rather than tying them to a fixed day.
