Croatia in September 2026: Weather, Sea and Prices
Is Croatia worth visiting in September? Weather, prices, sea temperature and everything you need to know
Croatia in September can be an even better choice than a holiday in July or August. The sea is still warm after the whole summer, the temperatures are perfect for both beach days and sightseeing, the roads and beaches are calmer, and finding attractive accommodation becomes much easier. If you are not tied to the school holiday calendar, September is one of the best months for a trip to the Adriatic.
Is Croatia in September a good idea?
September in Croatia is a transitional period between the peak of the season and a quieter autumn, but it should not be treated like a typical autumn month further north. On the Adriatic coast, conditions for a large part of the month still feel like full summer.
In Split the average monthly air temperature in September is around 21.6 °C, in Dubrovnik about 21.9 °C and in Zadar roughly 20.2 °C. These are averages that include both day and night. In practice, daytime temperatures very often reach around 24–26 °C, and during warmer spells they can exceed 30 °C.
That is exactly why September is such a good compromise for anyone who wants to spend time on the beach, swim in the sea, explore the towns and travel by car at the same time, without the fiercest July and August heat.
| Feature | July–August | September |
|---|---|---|
| Weather | Very hot, frequently above 30 °C | Usually warm, but far more comfortable |
| Sea | Very warm | Still warm after the whole summer |
| Beaches | Plenty of tourists | Noticeably calmer |
| Roads | Heavy traffic | Usually smoother driving |
| Accommodation | Highest seasonal prices | Better availability and often lower prices |
| Sightseeing | Heat can be exhausting | Very good conditions |
| Evenings | Very warm | Pleasant, cooler towards the end of the month |
Weather in Croatia in September – is it still warm?
Yes. On the Dalmatian coast in particular, September is still a very warm month. Keep in mind, however, that there is a considerable difference between the beginning and the end of the month.
First half of September
The period from roughly 1 to 15 September is the best choice if your priority is the beach and swimming. The days are still long, the Adriatic is thoroughly warmed up, and the weather often resembles the second half of August.
Second half of September
It can still be very warm, but the chance of cooler evenings, rainfall and short spells of unsettled weather increases. This is an excellent time for an active holiday, visiting the national parks, road trips and exploring Dubrovnik, Split, Zadar or Trogir.
| Place | Average September temperature | What the weather is like |
|---|---|---|
| Dubrovnik | approx. 21.9 °C | Very mild, plenty of warm days |
| Split | approx. 21.6 °C | Great mix of beach time and sightseeing |
| Zadar | approx. 20.2 °C | Warm, evenings can be cooler |
| Istria | usually slightly cooler than Dalmatia | Good for sightseeing and an active holiday |
The figures above are long-term climate averages. Check the specific forecast for your travel dates a few days before you set off.
What is the sea temperature in Croatia in September?
This is one of the strongest arguments for a September trip. The Adriatic releases its heat far more slowly than the air, so after July and August it stays thoroughly warm.
For Split, the long-term average water temperature in September is around 23–24 °C. At the start of the month the sea can be even warmer. For comparison, at the end of August 2026 official measurements by the Croatian meteorological service showed around 26–27 °C in Split and Zadar, and locally even more in the Dubrovnik area.
Can you swim in September? Absolutely.
For most visitors, the Adriatic in the first and middle part of September is perfectly comfortable for swimming, snorkelling and water sports.
If the warmest possible water is your main priority, choose Central or Southern Dalmatia and plan your trip for the first two weeks of September.
Does it rain in Croatia in September?
The risk of rain is higher than in July and August. That does not mean September is a rainy month that ruins a holiday. Most often you get occasional showers or thunderstorms interspersed with longer sunny spells.
The closer to the end of the month and the further north you go, the bigger the role changeable weather plays. It is also worth following reports about the strong bora wind, which can temporarily affect conditions on roads and bridges as well as ferry connections.
Prices in Croatia in September – is it cheaper?
September can work out cheaper than July and August, mainly when it comes to accommodation. The highest rates apply during the school holidays, when demand for apartments, hotels and holiday homes peaks.
Once the main season ends, more apartments become available and owners are more willing to offer better rates. That does not mean every hotel in Dubrovnik or every apartment by the beach suddenly becomes cheap. The most prestigious locations stay expensive for most of the year.
How much does accommodation in Croatia cost?
| Type of accommodation | Approximate price | Notes |
|---|---|---|
| Hostel | approx. €15–35 / night | Cheapest option for a solo traveller |
| Room / guesthouse | approx. €40–90 / night | Good option for couples |
| Apartment for 2–4 people | approx. €70–150 / night | Popular choice when travelling by car |
| Mid-range hotel | approx. €100–180 / night | Price depends heavily on the location |
| 4–5 star hotel | from approx. €200 | The priciest locations can cost far more |
In September it is particularly worth looking for apartments a few hundred metres away from the sea. The difference between the first row by the shore and a property 500–1000 metres from the beach can be substantial.

How much does food cost in Croatia in 2026?
Croatia is no longer a country where restaurants are clearly cheaper than in the rest of Europe. In popular coastal resorts, and especially in Dubrovnik, Split, Hvar or Rovinj, prices can be comparable to well-known Italian resorts.
| Product / meal | Approximate price 2026 |
|---|---|
| Espresso / coffee | €1.80–3.50 |
| Cappuccino | €2.50–4.00 |
| Pizza or pasta | €10–18 |
| Dish in a konoba | approx. €10–18 |
| Main course in a seaside restaurant | approx. €18–30 |
| Beer 0.5 l | approx. €4–6 |
| Scoop of ice cream | approx. €2–3.50 |
| Lunch for 2 people | approx. €45–70 |
| Lunch for a family of 2+2 | approx. €80–120 |
Travelling in September alone does not mean a big drop in restaurant prices. The biggest savings come from accommodation and from choosing places away from the main promenades and old towns.

Are there fewer tourists in Croatia in September?
Yes, and for many people this is the single biggest advantage of travelling after the peak season. As the school year begins, the number of families with children drops and the summer peak starts to fade.
Still, do not expect an empty Dubrovnik or a completely deserted old town in Split. Croatia remains a very popular destination in September too. The difference is clearly noticeable on the beaches, in car parks, on access roads and in smaller coastal towns.
01 Calmer beaches
It is easier to find a good spot even at popular swimming areas.
02 Less traffic
Driving between towns is usually far more comfortable.
03 Easier parking
This matters especially in small seaside towns.
04 Better sightseeing
Less heat and fewer crowds in old towns and national parks.
Where is the best place to go in Croatia in September?
The choice of region matters more in September than in midsummer. If you are mainly after swimming and high temperatures, head south. If sightseeing, an active holiday or a shorter drive matters more, Istria and Kvarner can be an excellent choice too.
Split and Central Dalmatia
One of the best choices for September. Warm sea, a wide selection of restaurants, ferries and attractions, plus the option to combine beach time with sightseeing. Trogir, Omiš and the towns between Split and Makarska also make good bases.
Makarska and the Makarska Riviera
A very good option if you still want full summer. In September the beaches are calmer, and the combination of the Adriatic and the Biokovo massif remains one of Croatia's most distinctive landscapes.
Dubrovnik
Exploring Dubrovnik in September is far more comfortable than during the peak summer heat. You should still expect plenty of tourists and high prices within the Old Town.
Zadar and Northern Dalmatia
A very versatile destination. You can combine beach days with sightseeing in Zadar and trips to Krka National Park, Paklenica or the Plitvice Lakes.
Istria – Rovinj, Pula, Poreč
Istria is the closest part of Croatia to Central Europe and works brilliantly for shorter trips. In September it is pleasantly warm, though statistically cooler and more prone to changeable weather than Southern Dalmatia.
The islands
Krk, Brač, Hvar, Pag and Korčula are much quieter in September. If you are travelling towards the end of the month, check current ferry timetables – outside the main season some connections run less frequently.
Croatia in September with children – is it worth it?
If your children are not school age yet, September can be the ideal time for a family holiday. Without extreme heat, travelling is easier, there is more space on the beaches, and a sea warmed up over the summer still allows long swims.
Families should give particular thought to the first half of the month. In the second half of September there is a slightly higher chance of changeable weather.
Who will enjoy Croatia in September the most?
Couples
More peace and quiet, easier restaurant bookings and a more romantic atmosphere.
Families with small children
Fewer extreme temperatures and calmer beaches.
Seniors
Comfortable temperatures for walking, sightseeing and relaxing.
Active travellers
Much better conditions for hiking, cycling and visiting the parks.
Road trippers
Less traffic than on the busiest summer weekends.
Budget-conscious travellers
Better accommodation availability and a chance of lower prices.
Driving to Croatia in September – is the journey easier?
For drivers, September is a very attractive time to travel. The biggest holiday departure waves fall in July and August, so once the school holidays end, traffic on the main transit routes usually starts to ease.
That does not mean you can skip the preparation. Before you set off, still check the situation on the motorways, roadworks, the tunnels in Austria, border crossings and roads in Slovenia, and the latest updates from the Croatian HAK and HAC.
We have described the individual route options in our guide route to Croatia 2026 – which vignettes and tolls do you need?
Which vignettes do you need to drive to Croatia?
In Croatia itself you do not buy a classic vignette for a passenger car. Croatian motorways are charged according to the section you drive. Vignettes are, however, required in the transit countries.
POPULAR ROUTE
Czech Republic → Austria → Slovenia → Croatia
On this route you need the relevant vignettes for the Czech Republic, Austria and Slovenia. In Austria, certain special sections and tunnels may be subject to additional tolls.
ALTERNATIVE ROUTE
Slovakia → Hungary → Croatia
This is often a very good option for drivers coming from the east, and usually the cheaper one in terms of tolls. You will need the Slovak and Hungarian e-vignettes.
DRIVING TO CROATIA?
Buy the e-vignettes you need before you leave
Check your route, select the right countries and sort out the road tolls before your journey even begins.
What to pack for Croatia in September?
Most of your luggage should still look like it would for a typical Adriatic holiday: swimwear, sunglasses, sunscreen, a hat and water shoes. The difference is that in September it pays to prepare for a cooler evening or one less sunny day as well.
The biggest advantages of visiting Croatia in September
Are there any downsides to a September trip?
The biggest downside is that the weather is less predictable than in midsummer. Towards the end of September in particular you may get cooler days, stronger wind and occasional rain. The days are also shorter than in June or July.
In smaller towns, some purely seasonal attractions, beach bars and services may reduce their opening hours towards the end of the month. On the islands, check ferry timetables more carefully.
For most people, though, these are minor inconveniences compared with the benefits: a warm sea, calmer beaches, less traffic and far more pleasant conditions for sightseeing.
Early or late September – when is the best time to go?
| Dates | Main advantages | Who is it for? |
|---|---|---|
| 1–10 September | Very warm sea, summer weather, fewer people than in August | The best time for a classic beach holiday |
| 10–20 September | A good compromise between weather, prices and peace | Couples, families, sightseeing + beach |
| 20–30 September | The most peace and quiet and excellent sightseeing conditions | Active holidays, city breaks, road trips |
The best compromise?
If you want to combine the beach, a warm sea, fewer tourists and reasonable prices, aim for roughly 5–20 September.
