Your April weather guide
MildWeather in Side in April
Side in April suits a mild-weather break rather than a holiday built around swimming and sunbathing. Average daytime highs are around 15°C, nights fall to about 8°C, and there are roughly 15 rainy days. For a UK traveller, the appeal is time outdoors when the weather allows, not dependable heat. Go if you are happy with layers and flexible plans; choose a warmer month if beach weather is the main reason for travelling.

How April compares
April is the 7th warmest month of the year in Side. Within Turkey it is 16th of 18 (Turkey in April). Against London's average high of 13.5°C in April, Side is 1.7°C warmer by day and 2.7°C warmer at night.
Daytime and night-time in April
The typical April day in Side peaks at 15.2°C, but that is an average: the warmest 10% of days reach 20.8°C or more. Roughly 1 in 53 days top 25°C and 1 in 1000 pass 30°C. Nights average 7.8°C; one night in ten drops to 4.0°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest April day here reached 30.6°C (1998-04-13) and the coldest night -6.5°C (2004-04-05).
Rain in April
Wet (more than 8 rainy days): about 15 days with 1 mm or more, 106 mm in total. Year to year it varies a lot - the wettest April was 1996 with 189 mm, the driest 2018 with 31 mm. Humidity averages 82%.
Sea temperature in April
The sea averages 10.1°C - too cold for most (under 18°c). Depending on the year it ranges from 8.7°C to 11.1°C. For the warmest sea here, come in August (25.5°C).
Sunshine and daylight
Around 5.2 hours of sunshine a day (estimated from cloud cover), 13.1 hours of daylight: the sun rises about 05:51 and sets about 19:09 local time in mid-April. Average cloud cover is 61%.
Is April a good time to visit Side?
April is not the strongest month here: mild days and frequent rain. The best months for Side on our scoring are July, August, June; months averaging 25°C or more: Jul, Aug.
Pack for cool evenings and regular rain
April calls for a light jumper and waterproof jacket rather than a suitcase built around summer clothes. The warmer days can reach around 21°C, but that is not the everyday expectation, and the coldest nights can fall to 4°C or below. Keep a warmer layer handy if you plan to sit outside after dark. With rain on about 15 days, shoes that cope with wet conditions are more useful than relying on sandals. That does not mean every wet day is a washout, but it does make weather-dependent plans a gamble. Leave room to move outdoor time around the forecast rather than committing to it in advance.
Daylight to use, but a cold sea
The sea is the clearest drawback for a beach-focused trip: at about 10°C, it is cold rather than merely refreshing. Even the warmer end of its April range is only 11°C, so do not plan around comfortable sea swimming. Time beside the water is a more realistic prospect, with an extra layer available when you stop moving. There are about 5.2 hours of sunshine within 13.1 hours of daylight, which leaves scope for outdoor plans without promising clear skies throughout the day. This suits travellers who enjoy being outside in mild conditions and can accept wet spells; it is a poor fit for anyone seeking reliable warmth.
