May, June and September are the best months in Split: warm sea, long days and half the crowds of high summer. July and August are hot, busy and expensive but have every ferry and every festival. Winter is quiet, cheap and genuinely pleasant if you like an empty old town.

Late May to late June, or the first three weeks of September. The sea is swimmable, the days are long, the boats all run, and you can get a table without booking three days ahead. If you want one answer, September. The sea has had all summer to warm up and the crowd has gone home.
April–May: 18–24 °C, sea still cold in April and fine by late May. Everything opens; prices are low. The bura wind can still cancel a boat in April, so leave a spare day.
June: the sweet spot. Warm sea, long days, manageable crowds, and accommodation has not yet hit the July peak. The best month if you want the full summer experience without paying for it.
July–August: 30 °C+, sea at 25 °C, the city full and accommodation at its peak. Ultra Europe in mid-July fills every bed. Mid-August is the busiest fortnight of the year because Croatia is on holiday too.
September: the locals' favourite. Warm sea from a whole summer of heating, thinner crowds, softer light, and the restaurants still have their summer menus and their summer staff. The best month, on balance.
October: still 20 °C, swimmable to mid-month, and a beautiful time to walk Marjan. Boat timetables thin out from mid-month.
November–March: 10–15 °C, rain in November and December, most island boats reduced, the old town returned to the people who live in it. Advent in December is the one bright spot; January and February are the quietest months of the year.
The middle two weeks of August, when Croatia itself is on holiday, and the Ultra Europe weekend in mid-July unless that is why you are coming. Cruise-ship mornings — the Peristyle between eleven and two — are avoidable any day by simply going somewhere else and returning at six.
The thing to understand is that the sea temperature lags the air by about two months. The air is hot in July but the sea is only properly warm from late July onwards, because it takes that long to heat through. September feels like the best summer month because the sea has caught up by then, and the air has dropped just enough to be comfortable. May feels cooler than it is, because the sea is still cold. If swimming is the point, come late. If heat is the point, come early.
Adventure
The pine-covered hill on Split's western edge, a fifteen-minute walk from the Riva and the reason the city feels liveable in August. Free, open always, with viewpoints, hermit chapels, swimming coves at the bottom and a proper trail network on top.
Adventure
An hour and a half up the marked path from Strožanac to the chapel of St George, topping out around 441 metres with Split, Kozjak, Mosor and the islands all in view. It is free, it starts at a supermarket, and locals walk it before work.
Family
The south side of Marjan drops straight into clear water over rock rather than sand, which is exactly what you want and exactly what the city beaches are not. Bring a mask, walk in off the stones at Kašjuni or Bene, and it costs nothing.
Nightlife
The hour before the Riva. A pine-shaded headland fifteen minutes west of the harbour, on the site of an old cemetery, where you sit on the wall with a bottle from the shop and watch the sun drop behind Čiovo. Free, no bar, no music — then walk back down for dinner.
History
A thirteenth-century chapel on the Marjan staircase, halfway between Varoš and the ridge. Small, usually locked, and the terrace in front of it is the quietest good view in Split — most people walk straight past on the way to Vidilica.
