Dubrovnik Weather in September

Warm days, passing showers

September still feels summery in Dubrovnik, but the heat eases after August. Highs reach 25°C, with around 8.4 hours of sunshine a day. You can explore the Old Town, walk the city walls, or take a boat to Lokrum without August's stronger heat.

Rain is more likely now: September gets 107 mm across 9 days, compared with 42 mm in August. Showers can interrupt a beach day or a hike up Mount Srđ, so keep a flexible plan. The sea can still make swimming appealing, but don't count on every day being dry.

Music and quieter streets

The Dubrovnik International Late Summer Music Festival brings classical concerts to the city in late summer and September. It's a good fit if you want an evening of music after a day outdoors. Croatia's school year also starts in September, and family crowds thin after the summer break.

If you hate crowds, you'll find the Old Town easier to enjoy than in July or August. The busiest summer stretch is over, and accommodation prices generally ease, though Dubrovnik remains a popular destination. The Dubrovnik Summer Festival is mainly a July and August event, so don't expect its full programme in September.

Make the most of a wet day

The weather is mild enough for sightseeing, but September is wetter than both August and October's sunshine can't be assumed. If rain sets in, duck into Rector's Palace or the Franciscan Monastery rather than spending hours exposed on the walls.

For the city walls, go when the forecast looks clear; wet limestone steps can be slippery. After your walk, try black risotto, a local dish made with cuttlefish ink, in the Old Town. It's a cosy way to end a cloudy afternoon.
