Which part of Croatia should you choose?
For warmth, Split and Dubrovnik are closely matched, with daytime averages of 26°C and the same sea temperature. Split has slightly cooler nights, so Dubrovnik may suit you better if warm evenings matter more than a little relief after sunset. Cavtat offers a useful compromise: days are a little cooler at 25°C, but its 5 rainy days make it the least rain-prone option here. Pula suits travellers who would rather keep daytime warmth gentler, averaging 24°C. The catch is its 8 rainy days, so leave more flexibility for outdoor plans. There is no sea-temperature advantage to choosing the warmer destinations: all average 22°C.
What to pack and how to plan your days
Pack light clothing for daytime, sun protection and a light layer for sitting outside after dark. With 9.8 hours of sunshine on average, there is plenty of scope for outdoor plans, but that does not mean every day will stay clear. The country average of 7 rainy days makes a light waterproof sensible, and it helps to keep plans movable rather than relying on uninterrupted sunshine. Put more active outings earlier in the day if you dislike midday warmth, then leave room for shade or a swim. The sea should suit many swimmers, though it may feel brisk on entry rather than like warm bathwater.
