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 cruises which depart at the start of April – a time when the maximum daily temperature hovers around 17°C with the Adriatic Sea averaging just 15°C.

Fast forward 3 months to the peak season of June, and the mercury is at consistent 30 degrees + with it often peaking well into the 40’s. The once quiet ports of Hvar and Korcula are well and truly buzzing, harbours are rammed with ships, a vacant grain of sand on Makarska beach is a rarity and the bars and clubs are heaving. It’s an awesome (and hot) time of the year!

April

April is the first month that you can expect good weather in Croatia. Temperatures rise to a pleasant level during the day, winds are milder and rain decreases overall. April is an optimal time to visit as the weather is fairly consistent and the tourist season hasn’t yet reached its peak. Daily average temperatures are 13°C in April. They can reach a high of 17°C and only dip as low as around 9°C.

Average sunshine hours is almost 13 hours at the beginning of the month, increasing to 14 by the end. If you’re a swimmer it might be too early to hit the beaches, but you can be sure of many warm sunny days to soak up the sun on the deck on your ship. The average sea temperature remains fairly chilly at 15°C, so unless you’re exceptionally keen, your bikini or board shorts might not get too wet during April.

May

May in Croatia is when temperatures really begin to climb and the summer season truly kicks off and our ships start departing weekly. The town and ports are filling up with tourists, restaurants and bars are alive, museums open and extend their hours, and the weather triumphs it all by warming up considerably.

Average temperatures reach a very pleasant high of around 21°C and reach a low of a very manageable 11°C. The amount of sunshine per day in May is about an average of 14.30 hours. Over the course of May, the amount increases about 1 hour.

Even with the warmer weather, the average rainfall during May is around 75mm over 10 days, so although it is likely to be generally dry and warm, there is still a risk of showers during your trip. We highly recommend that you pack something waterproof just in case. The average sea temperature during May is 18°C, so the braver among you may be tempted to head out for a swim – and for those of you who aren’t, the bars are always warm and inviting!

June

The weather in Croatia in June is one of the warmest you’ll experience – and also one of the busiest.

Daily average temperatures in June are about 22°C, highs reaching up to 27°C and lows plummeting to about 16°C. Over the course of the month, the hours of sunshine remain pretty constant, with an average of about 15 hours per day. The shortest day of the month is June 1 with 15.06 hours of daylight; the longest is June 21 with 15:20 hours of daylight. The average rainfall during June is only 75mm over 6 days, so it’s highly unlikely that you’ll be getting wet from precipitation during this month. Instead, you can expect dry, warm and glorious weather.

With the average sea temperature in June around 21°C, you’re likely to be in the water more often than not, so don't forget to pack your swimwear!

July

Sunscreen at the ready – July in Croatia is extremely hot and dry, and typically the hottest month of the year with average daily temperatures reaching around 28°C and only go as low as 16°C. The average sea temperature is its warmest of the entire year, reaching 24°C.

Pack your beachwear and swim gear!

August

There isn’t a great deal to say about the weather in Croatia in August – except that it’s extremely hot and dry. August is typically the hottest month of the year. There is, on average, 14 and half daily hours of sunshine.

The beginning of August is generous on sunlight with about 14.30 hours a day, and a daily average temperature of 25°C, highs of 28°C and lows of 21°C. Chance of precipitation is about 25% on average, fairly consistent over the month.

September

September is still extremely warm from the summertime, although it is usually much wetter than July and August. It’s generally a good time to visit if you’re thinking about joining on an Elegance Cruise as many of the 18-35yr olds have vacated the ports for the season. The water is still warm enough for swimming, and the restaurants and bars are yours for the taking.

The average daily temperature in September ranges from 16-19°C, with the highest still a lovely 24°C, and the lowest temperature is only around 13°C.

With the average sea temperature at around 23°C, it is still ideal beach weather. Light clothing such as t-shirts, shorts and sandals would be essential and hats and sunscreen with a high SPF would be essential to avoid sunscreen and sunburn.

October

Croatia is still fairly warm during October, but the temperature is noticeably lower and much wetter than the summertime. As days grow cooler and shorter, don’t forget to pack your cardigan and an umbrella. October’s average daily temperature is about 18°C over the course of the month, with highs decreasing from 22°C to 18°C and lows from 15°C to 12°C. Of course with temperature being lower at night, it would be wise to pack a few items such as a light jacket just in case.

The average daily rainfall has increased greatly to 162mm over 11 days. The average probability of precipitation is 37-45%, increasing over the month and occurring as light and moderate rain, and some thunderstorms. The amount of daily sunlight averages about 10.83 hours, and the length of the day decreases about 2.6 minutes daily over the course of month. The longest day of the month is Oct 1, with 11.44 hours of sunlight, and the shortest day is October 31 with 10.22 hours.

With the average sea temperature at around 20°C you would still be able to spend time on the beach and have a dip in the sea. A mix of clothes would be appropriate to take for a trip in October. You would be able to spend time at the beach so bring your swimwear, and t-shirts and sandals would do for being out and about during the day.


The weather in Croatia is as varied as our cruise types and there’s something for everyone and every budget. No matter which month you travel in, we highly recommend that you buy travel insurance before you leave home.
