Your July weather guide
HotWeather in Dubrovnik in July
July is a good time to visit Dubrovnik if you want hot days and a sea warm enough for swimming, but it is less suited to a trip built around walking in the midday heat. Average highs are around 28°C, nights stay near 21°C and the sea reaches roughly 25°C. For a UK traveller, that means a clear step up in warmth, with light clothing, shade breaks and somewhere comfortable to cool down becoming priorities.

Between 1991 and 2020 the hottest July day here reached 34.6°C (2007-07-24) and the coldest night 15.2°C (1993-07-10).

Some rain (4-8 rainy days): about 6 days with 1 mm or more, 40 mm in total. Year to year it varies a lot - the wettest July was 2014 with 120 mm, the driest 2003 with 5 mm. Humidity averages 67%.

Is July a good time to visit Dubrovnik?
Yes - it is one of the better months: hot days, manageable rain and long sunny days. The best months for Dubrovnik on our scoring are August, July, June; months averaging 25°C or more: Jun, Jul, Aug.
Expect heat rather than gentle summer warmth
July's warmth is fairly consistent: 91% of days reach 25°C, while 27% reach 30°C. That makes it a strong choice if you dislike cool summer days, but a less comfortable option if heat quickly tires you out. Plan longer walks for the morning and leave room for shade or an indoor break around midday. Humidity averages 67%, so do not assume the warmth will always feel dry. Evenings offer some relief, though an average night low of 21°C means they are still warm. Loose, breathable clothes and accommodation with cooling are sensible priorities, especially if warm bedrooms affect your sleep.
The sea is a reason to choose July
At an average 24.7°C, the sea is comfortably in swimming territory rather than something you need to brace yourself for. The year-to-year range of 24°C to 26°C also makes July a reasonable choice if swimming is central to your holiday. There is plenty of time to fit it around other plans, with about 11.8 hours of sunshine within 14.8 hours of daylight. Use that long day to spread out your time outdoors rather than staying in the sun throughout the hottest part. Pack swimwear, sun protection and a cover-up, and treat shade breaks as part of the day rather than an interruption.
Mostly outdoor weather, with room for rain
Rain is a possibility rather than a reason to rule July out. There are about 6 rainy days during the month, so it would be unwise to plan on an entirely dry holiday. That does not mean those days are wet from morning to night, but the figures cannot tell you when a shower will arrive or how long it will last. A light waterproof is a useful addition to otherwise summer-focused packing. Keep outdoor plans flexible and check the forecast nearer the time. July suits travellers who can accept some rain in return for hot weather, warm water and long, bright days.
