Weather in Montenegro in September: What to Wear, What to Pack, and More Visiting Tips

BY SARAH PAVLOVIC

The weather in Montenegro in September is perfect. I think September is the best month to visit Montenegro!

Why?

Because the sea is still warm enough for swimming but it’s not too hot. The summer crowds are gone, leaving the beaches empty for you to enjoy. And the vibe here is blissfully relaxed.

This guide will help you know what to expect from Montenegro weather in September. I’ve covered both the coastal and inland regions, so you'll learn what to pack for both - including the one thing not to pack!

I’ve also included some ideas for the best things to do in Montenegro in September. You’ll find some ideas for things to do on the coast, in the mountains, and ways to find authentic experiences to make your trip unforgettable.

Typical Weather in Montenegro in September

Coastal Areas

Average High in September: 25°C (77°F)
Average Low in September: 16°C (61°F)
Average Monthly Rainfall: 134 mm (5.3 inches)
Average Sea Temperature in September: 23°C (73°F)

In September, Montenegro's coast begins to cool slightly, which means the heat is pleasant rather than intense. You can expect temperatures from 16°C (61°F) at night to 25°C (77°F) during the day.

The first half of September is usually warm, with lots of beach weather and little, if any, rain. The evenings are a little cooler, ideal for a comfortable sleep without having to use air-conditioning all night.

The weather usually changes in mid- to late-September and it cools down noticeably. The weather is still pleasantly warm, but we get fewer true beach weather days. There’s more of a chance of rain too.

This month, you will still find plenty of activities on offer. I recommend visiting the Blue Cave, exploring Kotor, visiting Sveti Stefan’s incredible beaches, and planning some day trips.

Podgorica

Average High in September: 29°C (84°F)
Average Low in September: 14°C (57°F)
Average Monthly Rainfall: 145 mm (5.7 inches)

In September, Podgorica also experiences a welcome cool down from the intense heat of summer. You can expect warm days with temperatures ranging from 14°C (57°F) at night to 29°C (84°F) during the day.

This month combines the warmth of summer with the cooler, more comfortable evenings of early fall, making it ideal for sightseeing, swimming, and enjoying the city's cafes and parks.

In September, I recommend taking a morning city tour before it gets too warm. This is also a good time to take a day tour to nearby sights like Ostrog Monastery.

If you have a rental car, I highly recommend making the short drive to Lake Skadar National Park. There, you can take a boat tour, hire kayaks, and find fantastic wine and food tasting tours at the best wineries in Montenegro.

You can also take a day trip to the beautiful Biogradska Gora National Park, which is one of the last remaining primeval forests in Europe. Read my page about Kolašin to find some fantastic authentic restaurants for your trip.

If you don't have a car, you can do this trip on a tour too.

Northern Region

Average High in September: 20°C (68°F)
Average Low in September: 9°C (48°F)
Average Monthly Rainfall: 117 mm (4.6 inches)

In September, Montenegro's northern region also feels the early signs of autumn. Temperatures become milder, ranging from 9°C (48°F) at night to 20°C (68°F) during the day.

This slightly cooler weather is perfect for outdoor activities like exploring the national parks without the summer heat.

In Durmitor National Park, rafting through the Tara Canyon is a calm and relaxing experience. The Black Lake, Lovćen National Park, and Biogradska Gora National Park are stunningly beautiful as summer greens transition into autumn reds, oranges, and yellows.

Likewise, Lake Skadar National Park starts to prepare for cooler weather, but September wine and brandy production ramps up and it’s a perfect time to visit a winery here.

Prokletije National Park is off the beaten track for most visitors to Montenegro, but it’s a popular destination for serious hikers.

What to Pack for September in Montenegro

Coastal Areas

In September, the Montenegrin coast begins to cool slightly, but the weather remains warm enough for summer clothing, especially in the first half of September.

Lightweight and breathable fabrics like cotton and linen are still the best choice. You’ll need t-shirts, shorts, and sundresses for the daytime. The evenings can get slightly cooler, so bring a light sweater or jacket.

It is also a good idea to pack a dressy outfit for the evenings. A nice dress and sandals (heeled or flat, but I don’t recommend stilettos because of the cobbled and uneven streets here) are ideal for women.

For men, I recommend slacks or jeans and a short- or long-sleeved shirt.

The sea is ideal for swimming, so don't forget your swimsuit. I also recommend a hat, sunglasses, and sunscreen for the beach.

You’ll need comfortable walking shoes or sandals for sightseeing. You’ll do a lot of walking in Montenegro because the old towns are pedestrian-only, so comfort is a priority!

The second half of September can be much cooler, with more chance of rain. If you’re visiting at this time, I recommend packing more trousers, jeans, and long sleeves for layering.

Packing List:

Cotton or linen tops
Cotton sundresses
Skirts and shorts
Light trousers or jeans
Long sleeves for layering
Dressy outfit
Swimsuit
Comfortable walking shoes and sandals
Light sweater or jacket for evenings
Hat
Sunglasses
Sunscreen
Chill Pal - this towel is amazing for sightseeing here in summer. Just wet it and it will stay cold and keep you cool for hours!
Beach towels - Most accommodations in Montenegro don’t provide beach towels, so pack these too.

There are virtually no laundromats in Montenegro, so if you don’t have a washing machine in your accommodation, it can be difficult to wash your beach towels.

To get around this I love these microfiber beach towels, which are lightweight, quick drying and you can easily wash them in your shower if needed.

Plug converter - I like this power strip converter that can handle several devices at once. It’s ideal for families bringing multiple devices!
Travel insurance - this is a must when traveling to Montenegro. Not only will it cover things like lost luggage and flight delays, but more importantly, any medical issues that you might have.

Montenegro’s public health system is rather poor, so I always recommend going private if you have any issues while you’re here and travel insurance will cover that.

Having medical evacuation cover is essential in Montenegro because if you have any serious issues you may need to be transported to another country.

I like Safety Wing’s Nomad Insurance (you can buy it just for a trip) because it’s the best value and most comprehensive cover I’ve found so far.

What Not to Pack:

Hair straightener/curling irons - In Europe, the voltage is 220, while in the US and Canada, it’s 110.

Most electronic devices such as cell phones, laptops, and electric shavers are dual voltage by default, so you can use them with a simple plug converter.

Unfortunately, hair straighteners and curlers use very high wattage and do not usually come with a dual-voltage setting, which means they won’t work in Europe.

Or rather, you’ll fry your appliance and short-circuit your hotel room!

If you can’t use your own hair appliances, your best option is to bring a dual-wattage straightener that will work in Europe and North America.

Mountain Regions

In September, Montenegro's inland regions experience mild weather, with warm days and cooler nights.

The best things to bring for this time of year are layers that will allow you to be comfortable in the changing temperatures.

Lightweight, breathable clothing is ideal for daytime activities, and you’ll also need a sweater and jacket for cooler evenings or sudden temperature drops.

It can get as low as 9°C (48°F) in the mountains in September, so pack enough warm clothes if you’re planning to visit this region, even on a day trip.

You’ll also need sturdy footwear for hiking or walking through uneven terrain in areas like Durmitor National Park.

Packing List:

Lightweight, breathable clothing
Long pants/jeans
Sweater and jacket for cold weather
Sturdy footwear
Hat and sunglasses
Waterproof jacket
