Rovinj Weather: A Month-by-Month Breakdown

Hey there, future Rovinj explorers! We’re locals who’ve spent our lives in this stunning corner of Croatia’s Istrian coast, and we’re beyond stoked to share everything about Rovinj weather with you.

We at Rent a Boat Rovinj by Mare Media have experienced every season firsthand—from blazing summers to crisp winter days—and we can’t wait to break it all down. Whether you’re dreaming of renting a boat, chasing dolphins, or just kicking back by the Adriatic, knowing what Rovinj weather’s got in store will help you plan the perfect trip.

We’ll guide you through each month—temps, rain, vibes, the works—and let you know who should visit when. Let’s dive into Rovinj’s climate together!

Rovinj’s Climate: Our Big Picture

We’ve got that classic Mediterranean climate here in Rovinj—hot summers, mild winters, and heaps of sunshine. We’re talking over 2,500 sunny hours a year, which is why this place feels like a nonstop vacation spot for us. Summers climb to 28-30°C (82-86°F), ideal for swimming and boating, while winters settle at a cool but manageable 5-10°C (41-50°F).

Rain’s pretty even throughout the year, though fall gets a bit wetter, and spring keeps everything fresh. The Adriatic Sea gives us a nice breeze, so even the hottest days don’t feel oppressive. Basically, Rovinj weather sets us up for outdoor fun—especially when we’re out on the water.

Alright, let’s get into our monthly rundown!
