Your April weather guide
MildWeather in Split in April
April is a reasonable time to visit Split for mild days outdoors, but not for a beach holiday built around swimming. Average daytime highs are 17°C, nights fall to around 10°C, and the sea is cold at 14.2°C. For a UK traveller, the appeal is comfortable weather for exploring rather than reliable warmth. Go if you are happy to wear layers and change plans for rain; choose summer if heat matters most.

Daytime and night-time in April
The typical April day in Split peaks at 17.2°C, but that is an average: the warmest 10% of days reach 21.0°C or more. Roughly 1 in 167 days top 25°C. Nights average 9.6°C; one night in ten drops to 5.9°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 26.5°C (2018-04-20) and the coldest night -0.3°C (1995-04-01).

Wet (more than 8 rainy days): about 11 days with 1 mm or more, 100 mm in total. Year to year it varies a lot - the wettest April was 2004 with 186 mm, the driest 2007 with 12 mm. Humidity averages 72%.

Mild days, but keep a jacket handy
Split in April suits travellers who prefer walking without strong heat. The average high is comfortable with a light layer, although it is not a promise of shirtsleeves all day. Warmer spells can reach 21°C or more, so pack something lighter for sunny afternoons, but leave room for a jumper and jacket. Evenings need more thought: the average low is around 10°C, and the coldest nights can fall to 6°C or below. If you plan to sit outside after dark, dress for the temperature dropping rather than the warmth you felt earlier. Midday is a sensible time to enjoy any warmth; persistent summer heat is not the concern here.
Allow for rain and a cold sea
Rain is a meaningful catch, with about 11 rainy days during April, so avoid making every plan depend on staying outdoors. A waterproof jacket and shoes that cope with wet pavements are more useful than packing only for sunshine. There is still about 6.5 hours of sunshine a day on average, leaving scope for pleasant outdoor time, but not guaranteed clear days. The sea is the bigger limitation for a beach-focused trip: at 14.2°C, it is cold rather than merely refreshing. Even the warmer end of its usual range, 15°C, does not make it comfortable swimming water. Treat time by the water as a dry-land pleasure unless you already enjoy cold-water swimming.
