Despite its relatively small landmass, Croatia experiences a coastal and continental climate. If you’re planning on spending your time along the beautiful Croatian coastline, here’s what you can expect from the coastal climate.
Along the Adriatic coast you’ll find that the weather is a typical Mediterranean climate. This usually involves days that are hot and sunny through the summer and a temperament, occasionally wet winter with milder temperatures. It’s not uncommon for the summer weather to linger into autumn, with sunny, warm days that can have you comfortably exploring the versatile coastline during the off-peak seasons.
Croatia doesn’t have the extreme weather differences that many European countries experience; however, there is still considerable contrast between pre-season & peak-season conditions. This will not only have an effect on your travel plans, but your overall holiday budget too. The very first Sail Croatia departures of the season are our Elegance Croatia Cruises which departs at the start of April – a time when the maximum daily temperature hovers around 17°C, making it the perfect time of year to be relaxing and exploring in the sunshine.
Fast forward a couple of months to the peak season of July, and the mercury is at a consistent 30 degrees. The once quiet ports of Hvar and Korcula are well and truly buzzing, harbours come alive with travellers near and far, and the bars and clubs are heaving. It’s an awesome (and warm) time of the year!
