Is September 2027 a good month to visit Dubrovnik?
Busy — the typical September day in Dubrovnik is busier than 76% of its year.
If you are coming for something that only happens in September, that is the trade. If not, December is quieter.
Calm · Lively · Busy · Packed rank a day against Dubrovnik's own year — not a headcount.
September is one of Dubrovnik's busiest months: warm and showery, around 26°C / 79°F with rain on about 8 days, and Busy on 16 of 30 days.
It depends. The typical September day in Dubrovnik is Busy, and 24 of the 30 days in our window run Busy or Packed, so most days feel crowded. Expect around 26 °C by day, with rain on about 8 days. The crowd comes with the school holidays in Germany and the Netherlands. Cruise ships call on 25 of the 30 days, 5 at once on Tuesday 28 September. Mid September is the month's quietest stretch in Dubrovnik — the typical day at 72%, against 80% in late September. For similar weather with fewer people, come in October or May. The crush is at the Pile gate and the Stradun; the quiet is at Lokrum. The calmest day is Friday 17 September, the busiest Thursday 16 September.
In short, worth it for the peak buzz, if you can take the crowds.
Among the 12 months we forecast for Dubrovnik, September ranks 3rd for crowd pressure. Its heaviest day is Thu 16 Sep, busier than 97% of the year; its lightest is Fri 17 Sep at 58%.
Preparing pays off in a month like this: timed-entry tickets and pre-booked tours turn the queue time into sightseeing time. see the options →
Nothing extreme to plan around — rain on 8 of 30 days.

How busy is Dubrovnik in September?
The busiest days are the 1st, 16th, 28th and 30th, and 20 more. Away from those, most days sit Lively.
Cruise ships are in port on 25 of 30 days; the heaviest is Tue 28 Sep, 5 ships in at once. Those mornings fill the squares first — start early, or save them for indoors.
The month is not one thing: its lightest day sits at 58% of the year and its heaviest at 97%, so where you land inside it matters. All five Wednesdays run Busy or Packed. Daylight runs about 12 hours.
Either side of it, August is busier still and October is far calmer.
The calmest days are the 17th, 24th and 27th — aim for those if your dates can flex.

Which week of September is quietest in Dubrovnik?
Mid September is the month's quietest stretch in Dubrovnik — the typical day at 72%, against 80% in late September.
Can't move the dates? How to avoid the worst crowds
- The heaviest port day is Tue 28 Sep — 5 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
Travelling on a busy day?
Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.
September weather in Dubrovnik
Comfortably warm — around 26°C / 79°F, easy shirtsleeve weather, with rain on about 8 days, so keep a layer handy.
Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
