Weather in Split in July
Croatia · 20-year averages, July
Prime time. If you get to pick your dates, July is the one. Highs average 29.9 °C, lows 22.6 °C, and rain falls on 5 days — nothing in the month is working against you.
July ranks 5 of 12 in Split: past the worst of the year but short of June, which is the month to book if the dates are open.
Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29.9 °C days and 22.6 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 15 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 36.9 °C and the coldest night fell to 16.1 °C, and the wettest single day dropped 29 mm — roughly 100% of the month's rain in one day.
This is the volatile part. July rainfall has ranged from 3 mm to 97 mm across the twenty years measured — a 94 mm spread around an average of 29 mm. The average is real but almost no individual July looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 8.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 58%.
How July sits in the year
Temperatures hold steady either side: 26.5 °C in June, 29.9 here, 30.1 in August. Nothing about the timing within the month matters much.
Daylight in July
July is at or near the longest days of Split's year: 15.1 hours of daylight, losing 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
Despite being inland, the year stays fairly even: 23.8 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Split versus nearby
If Split is one option among several, the nearby comparison is worth making. Dubrovnik is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Slavonski Brod is the weaker option in July — within a degree on temperature, 5 days more rain.
So: July is effectively as good as it gets here — 6 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
