Croatia Split Weather in July — Climate Guide
July in Split is high
July is high for Split.
July is peak summer in Split — perfect beach weather, but the hottest, busiest, and most expensive time to come. It averages 31°C/21°C with near-constant sun and almost no rain.
The upside is undeniable: a warm ~24-25°C sea, every island and beach in full swing, and the Split Summer Festival (mid-July to mid-August) bringing open-air theatre, opera, and concerts to historic settings like the Peristyle. Long, hot days are made for island-hopping and late swims.

Split in July — Full Picture
July is peak summer in Split — perfect beach weather, but the hottest, busiest, and most expensive time to come. It averages 31°C/21°C with near-constant sun and almost no rain.
The upside is undeniable: a warm ~24-25°C sea, every island and beach in full swing, and the Split Summer Festival (mid-July to mid-August) bringing open-air theatre, opera, and concerts to historic settings like the Peristyle. Long, hot days are made for island-hopping and late swims.
Be honest about the downside: the Riva and palace alleys are packed with cruise day-trippers and tour groups, catamarans to Hvar and Brač sell out, popular konobas need reservations, beaches fill up, and accommodation roughly doubles. The marble alleys radiate heat at midday.
Plan sightseeing for early morning and evening, take a midday beach or shade break, and book everything — stays, ferries, dinners — well ahead. Pack the lightest clothing, swimwear, reef shoes, and serious sun protection.
What to Wear & What to Pack
Peak summer heat — around 31°C/21°C, hot and dry. Light, breathable clothing, swimwear, hat, sunglasses, SPF 50. The sea is warm (~24-25°C). Avoid midday sun on the marble alleys.
