For swimming, Dubrovnik and Cavtat have a slight edge, with sea temperatures of 25°C compared with 24°C in Split and Pula. Cavtat also has the fewest rainy days of these destinations, making it the strongest choice if avoiding rain is your priority. Dubrovnik offers similar air and sea temperatures, but rain is more likely to interrupt your plans.
What to expect from a July day
With 11.4 hours of sunshine on average, July gives you plenty of scope to spend time outdoors without putting every activity into the hottest part of the day. Plan more active outings for the morning, leave room for shade around midday, and keep swimming plans flexible rather than tied to a rigid schedule. Lightweight clothes, a sunhat and sun protection are sensible packing choices. Nights average 21°C, so evenings generally call for light clothing rather than heavy layers; accommodation with cooling is worth considering if you struggle to sleep in warmth. Rain remains possible, so keep a light waterproof handy and allow some flexibility.
