Dubrovnik in July

When to go

July is when the Dubrovnik Summer Festival gets under way: its most recent programme began in July and ran into August, and the festival says it will announce its next programme in February, so exact dates for your trip may not be out until then. The facts below give the Croatian weather service's mean highs, lows, rainfall and rain days as relayed by the World Meteorological Organization, plus a sea temperature from the service's own climate-normals table. The City of Dubrovnik's visitor-number prediction tool can help you judge how busy the historic core may be on a given day.
