Split in May — Full Picture
May is arguably the best month to visit Split — warm, sunny, and lively without the July-August crush. It averages 23°C/14°C with long days and little rain.
The city is in full swing: all-day sightseeing in summer clothes, ferries running near-full schedules, and the islands (Hvar, Brač, Vis) easy to reach. By late May the Adriatic warms toward swimmable (~19-20°C), so beach time becomes a real option alongside the palace, Marjan, and Krka.
Crowds and prices are higher than April but still well below peak — you'll want to book popular konobas and catamarans ahead, but the city doesn't feel overrun. Sunsets from Marjan Hill are glorious this month.
Pack light summer clothing, a hat, sunglasses, and sunscreen, with a light layer for the evening. For the best balance of weather, swimmable sea, and manageable crowds, May is hard to beat.
What to Wear & What to Pack
