Best time to go to Dubrovnik and Islands
The Dubrovnik region starts heating up from May onwards, when the mercury rises from around 20°C, to a peak of about 30°C in August. In fact, it’s still toasty in September, when the high season has wrapped up. If you’re more of an early bird, you’ll still get plenty of blue-sky days in April, although it’s a little chilly for a dip in the Adriatic.
