When to Visit Montenegro: Month by Month

The short answer: mid-June or the second half of September. The sea is already — or still — warm, there are half as many people as in August, and accommodation is roughly a third cheaper. So is the car: in July and August hire costs about twice what it does in May. If you are coming for the mountains rather than the beach, May is the month.

Here is what actually happens each month: air and water temperature, what is open, what is shut, and what it costs. Public holidays and festivals by date — the Kotor carnival, the Fašinada, Boka Night — have a calendar of their own: Montenegro’s holidays and festivals.

April: green, cheap, too cold to swim

Around 18–20 °C by day and a sea at roughly 15 °C — a temperature only the brave get into. But everything is in flower, the slopes are green, and snow still sits on the mountains: from the coast you can see the white tops of Lovćen.

Not everything is running. Some beach cafés and hotels open only in May, and group excursions to the north are not yet going — the passes can still be closed.

Car hire is at its cheapest of the year. Roads are empty, parking is free of drama, and this is the best month for anyone who came to see the country rather than lie on it.

May: the best month for the mountains

22–24 °C by day, sea at 18–20 °C. By the end of the month people are swimming, though the water still wakes you up.

May is when Montenegro looks its best: the green has not burnt off, the air is clear, and in Durmitor the snow is melting and the lakes are full. Northern excursions start, and the first pleasure yachts go out.

Few people, low prices. If your holiday is not tied to school terms, this is the best trade-off between weather and cost in the calendar.

June: the season opens

27–29 °C, sea at 22–24 °C. A full beach season without the August crush.

The first half of June still has low prices and parking spaces to spare. After the 15th the curve turns: European visitors arrive, hire prices climb, and weekend boats get taken well in advance.

This is the month people recommend most often, and they are right to.

July: hot and busy

30–33 °C by day, sea at 25–26 °C, and practically no rain.

The real season begins: Budva and Kotor fill up, cruise ships come into the bay almost daily, and the old-town car parks are full by mid-morning. Car hire costs roughly twice what it did in May, and you want to book a month ahead.

The upside of July is that absolutely everything runs — every excursion, every beach bar, every ferry and cable car.

August: peak everything

32–35 °C, sea at 25–26 °C: the water is at its warmest from late July through August. And the thickest crowds.

August is for people with no choice: school holidays and fixed company leave. Accommodation is at its maximum, parking in Kotor is a project, and the switchbacks get queues that simply do not exist in May.

If you are coming in August, plan earlier: cars, boats and excursions all go two to three weeks in advance.

September: the second-best month

First half: 28–30 °C with a sea at 24–25 °C — warmer than June. Second half: 25–27 °C and 23–24 °C in the water.

The crowds clear after 25 August, prices come down, and the sea holds its heat into October. For adults travelling without school-age children, September beats August on every measure except one: the first rain can arrive late in the month.

October: warm sea, empty country

20–24 °C by day, sea at 20–22 °C. You can still swim; few people do.

By mid-month the northern coach excursions wind down; the group boat trips around the bay stop even earlier, in mid-September. Some beach places close. In exchange, Kotor and Budva are yours, and car hire is back to spring prices.

In autumn 2026 Đurđevića bridge over the Tara is closed for reconstruction until 26 October, though it is expected to reopen sooner. If the bridge is the reason for your trip north, check before you go.

November to March: a different country

The coast sits at 10–15 °C with a lot of rain — November and December are the wettest months of the year. The swimming season is over and much of the tourist infrastructure with it. Njegoš’s mausoleum on Lovćen is open from 15 April to 15 November and closed in winter.

The date matters for visas too. From 1 November 2026 citizens of Russia, Belarus, Turkey, China and Saudi Arabia need a visa for Montenegro; if that includes you, apply a month to six weeks ahead. Nothing changes for British, EU or US passport holders: up to 90 days without a visa (for UK citizens, 90 days in any 180; for EU citizens travelling on an ID card, 30 days). Details are in Montenegro entry requirements. And whatever your passport, do not count on your home tariff: Montenegro is outside the EU, so UK and EU “roam like at home” deals do not cover it — see mobile internet in Montenegro.

But the north is alive: Žabljak and Kolašin run ski lifts from December to March. Getting there in winter needs attention and sometimes winter tyres — there is snow on the passes. Kolašin’s pistes and ski pass prices are in Biogradska Gora and Kolašin.

January and February are when the country is nearly empty and prices are at their lowest. If your target is towns, monasteries and food rather than the sea, this works.

By what you want

• Beach and warmth without crowds — the second half of June or the first three weeks of September.
• Mountains, hiking, photography — May or early October.
• The warmest sea — late July and August, if you accept the people and the prices.
• Cheap and quiet — April, late October, winter.
• Skiing — January and February, Žabljak or Kolašin.

What this means for booking

At sea. Pleasure yachts run May to October; catamarans run longest, being least bothered by swell. In July and August a weekend boat goes a week or two ahead. Prices and the difference between a yacht and a catamaran are on the yacht charter page and in Bay of Kotor cruise from Tivat.

Excursions. Coach routes north run May to mid-October; the boat trips around the bay only from mid-June to mid-September, and not at all in winter — the passes are under snow and the ship has no heating. Every format with prices is under things to do.

Cars. The gap between May and August is roughly double. Out of season you can pick a car up the day before; in July and August you cannot — what is left costs more. What to check at handover is in rental car pitfalls and how to book a car online. Prices and models are on the car rental page.

A five-day route that works equally well in May and September is in Montenegro by car in 5 days.
