Croatia Weather in May and Summer Months

One of the most important things for all yachters is weather conditions. Croatia has differing geography but the weather stays similar around the country for the most part. Croatia’s climate becomes more Mediterranean the closer you get to the coast and the Adriatic Sea keeps the area cooler down during the summer months. Here are some useful pieces of information about the climate, wind, and temperature from May till October!

What’s the weather in Croatia in May?

The rainy days will start reducing while temperatures generally start to rise in May as summer gets closer. Croatia weather in May differs from region to region, and from town to town, but popular coastal cities have a typical high temperature of 21ºC in May. The lowest it can go, especially during the night is 11ºC. If you plan to cruise at this time make sure to bring some long sleeves and an umbrella if you want to explore towns during the day so rain doesn’t surprise you on the way.

Sea temperatures are around 18ºC, so children or those who are not feeling brave perhaps won’t find that temperature comfortable for swimming. UV levels will be high on sunny days so having a sun cream is advised to bring and use. 

What is the weather like in Croatia in June?

Croatian weather in June gets kind of similar all around the country, and no matter which coastal town you visit you will be able to enjoy sunshine and warmth during June.

If you are going to major cities like Split or Dubrovnik in June the daily temperature will be 25ºC. During your cruise, you will be able to enjoy the sea that reaches a temperature of 22ºC and more. 

We advise you to bring sunscreen, shorts, and T-shirts, with a few extra long sleeves if the evenings get a bit cooler.

Since the Croatian coast falls under the Mediterranean climate you can expect hot weather if you’re going to a yacht in Croatia in July. You’ll be able to keep cool by swimming in the sea that reaches 24ºC which is very comfortable for swimming and watersports but still very refreshing.
