In the Northern Hemisphere, September means the end of the holiday season for most people. Yet summer does not really end; it merely retreats southwards on the map. While the sea maintains its leftover warmth from summer on the southern shores of the Mediterranean, some islands in the Atlantic Ocean continue to enjoy sunny days. In the Red Sea and the Arabian Peninsula, the suffocating heat of summer drops to much more favorable levels for travel with the arrival of autumn.
Therefore, when planning a sea holiday in autumn, asking only "Where is warm?" is not enough. September, October, and November are three quite distinct travel periods. While the Mediterranean remains a strong option in September, it becomes necessary to move further south in October, and closer to the tropical belt or the Red Sea in November. Along with air temperature, sea water temperature, wind, rain probability, and the operating schedule of seasonal businesses also determine the right route.
The best autumn holiday is less about finding the hottest place and more about choosing the right destination in the right week. While some routes still experience high summer in September, others truly become beautiful in October and November.
Short answer for a sea holiday in autumn
- In September: Kaş–Çıralı line, southern shores of Crete, Cyprus, and Gozo
- In October: Cyprus, La Gomera, Taghazout, and Marsa Alam
- In November: Canary Islands, Red Sea, Oman, and Cabo Verde
Now let's look at these routes by stepping slightly outside the well-known holiday centers.
Kaş, Adrasan, and Çıralı: Second summer in the Mediterranean
To look for a warm route in autumn, it is not always necessary to change countries. The southwestern coasts of Turkey, especially in September and early October, are among the most accessible options for those who want to continue their sea holiday. Around Antalya, the sea temperature can remain suitable for swimming in October; the Taurus Mountains also protect the coastline from cool air currents coming from the north.
However, this time it is worth looking at the Kaş, Adrasan, and Çıralı line rather than major resort centers. The coves that are quite busy during the summer months quiet down with September. Boat routes stretching from Kaş to Kekova, small coves around Adrasan, and the long beach of Çıralı transition to a lower pace. The slight drop in temperature makes it possible to walk short stretches of the Lycian Way in the morning hours and swim in the afternoon on the same day.
Best time: From mid-September to mid-October.
Southern shores of Crete: The island's quieter face than summer
Although the season in the Greek islands is often described as over by the end of August, the weather remains mild in September and October, and the sea maintains its leftover warmth from summer. One of the best equivalents of this is heading towards the southern coasts of Crete instead of its popular northern centers.
Loutro, which cannot be reached by road, Paleochora, suitable for longer stays, and Triopetra, preserving its wild coastal appearance, offer a different experience from the dense resort centers around Chania and Heraklion. The main advantage of Southern Crete is not just the sea. Thanks to mountain villages, small tavernas, and hiking routes, even if the weather changes for a few hours, the whole day is not lost.
As October progresses, it is necessary to take into account that some seasonal businesses may close and boat trips may decrease. This route is suitable for those seeking quiet coves, local cuisine, and a slow island experience rather than nightlife.
Best time: September and the first half of October.
Cyprus: Summer coming closest to November in the Mediterranean
Cyprus is one of the most reliable options in the Mediterranean for those wanting to swim in autumn. Open sea temperature generally hovers above 22°C from June to November. September and October are a strong period for swimming, sunbathing, and water sports; in November, sea enjoyment can continue depending on weather conditions.
It is also possible to go beyond the classic beach centers in Cyprus. The hiking trails and small coves of the Akamas Peninsula, the quieter shore of Pissouri, or the wine villages in the interior of the island add different layers to a sea holiday. Thus, travel does not remain dependent solely on the expectation of a sunny day.
If planning for November, a flexible program is more appropriate: sea during noon hours, and culture, gastronomy, and nature routes during morning and evening hours.
Best time: September, October, and depending on weather conditions, the first half of November.
Gozo: Malta's quieter sibling
Malta is a strong option for those wanting to combine a sea and culture trip in September and October. However, the place that deserves real attention in autumn is not the main island, but Gozo. With its small scale, rocky shores, hiking trails, and slow-paced daily life, the island offers more than a short sea getaway.
Ramla Bay's reddish sand, coastal formations around Dwejra, Xwejni salt pans, and the historic Citadel in Victoria allow easy transitions between beach and culture. While September is still suitable for a swimming-focused holiday, in October it is more appropriate to balance sea days with island walks and village tours. November can be mild; however, this month should not be planned with the expectation of swimming alone.
The real value of Gozo in autumn is that it is more local, quieter, and more walkable compared to the crowded Malta experience of summer.
Best time: From mid-September to the end of October.
La Gomera: The Canary Islands' option far from crowds
When looking for sun and sea relatively close to Europe in November, the Canary Islands are a constant on the list. La Gomera, one of the lesser-known members of the archipelago, appeals to those who want to step away from large resorts and combine their holiday with nature.
Choosing La Gomera instead of the large resorts of Tenerife and Gran Canaria completely changes the character of the holiday. Volcanic coves, black sand beaches, and Garajonay National Park on the UNESCO World Heritage list meet on the same small island. While the area around Valle Gran Rey stands out for swimming and sunsets, Playa de Santiago offers a quieter coastal life.
In October, average temperatures across the archipelago reach around 26°C, while daylight duration stays around 10 hours. The Atlantic Ocean may feel cooler than the Mediterranean; in contrast, sun, hiking, and outdoor activities continue strongly throughout autumn.
Best time: October and November.
Taghazout and Tamraght: Ocean rhythm rather than a beach holiday
When a warm route in autumn is mentioned, Morocco is often thought of through Marrakech. However, Taghazout and Tamraght, north of Agadir, offer a different coastal experience starting from October. The main surf season in the region starts in October and continues until spring.
Taghazout is no longer just a small fishing village visited by surfers. Surf camps, yoga centers, design-oriented small hotels, and modest restaurants serving seafood make the region suitable for an active holiday of a few days. Neighboring Tamraght can be preferred for quieter accommodation; during the day, one can cross over to Taghazout coves and around Anchor Point.
The important distinction here is: The Atlantic Ocean is not as warm as the Mediterranean. For this reason, the route appeals to those seeking sun, surf, beach walks, and ocean views rather than long swimming days in the classic sense.
Best time: October and November; the season gets stronger towards winter for surfing.
Marsa Alam: The Red Sea's lesser-known underwater route
For those who do not want to risk sea temperature in October and November, the Red Sea is a strong option. While Sharm El-Sheikh and Hurghada are better known, Marsa Alam sets itself apart with reefs close to the shore, rich marine life, and a less developed coastline. Although the region has long been on the route of experienced divers, it is still a relatively undiscovered option for those seeking a quiet sea holiday.
Marsa Alam's difference is that underwater life does not belong only to professional divers. Snorkeling around Abu Dabbab, seeing Sharm El Luli beach in Wadi El Gemal National Park, and reaching offshore reefs by boat are all possible. Since the region's resorts are more scattered than Hurghada, direct access to the beach and reef is important when choosing a hotel.
Red Sea coasts can remain warm and sunny even in winter months. Autumn offers the balanced window between the extreme heat of summer and the windier days of winter.
Best time: October and November.
Oman: Adding the sea to the same route as desert and mountains
Oman stands out in autumn not only as a warm coast, but for those seeking geographical diversity. Temperatures drop gradually from September to November, and the autumn average hovers around 28°C. The same period coincides with the timeframe when whale shark migration can be observed off Muscat around the Ad Dimaniyat Islands and Musandam.
A few days of city and beach program in Muscat can be combined with snorkeling or diving in Dimaniyat. On a longer trip, the Hajar Mountains, Nizwa, and desert camps can be added to the route. Salalah in the south appears completely different from the rest of the country with its green Dhofar landscapes following the summer monsoon and its long sandy beaches.
The main attraction of Oman is that, unlike the glamorous city holidays of neighboring Gulf destinations, it combines coast, culture, and nature in a more measured experience.
Best time: Late October and November.
Boa Vista: Island opening to the dry season in November
For those planning a more distant sea holiday towards the end of autumn, Cabo Verde's Boa Vista island is a strong but still little-discussed alternative in Turkey. The dry season begins in November in the archipelago off West Africa. Low rainfall, mild temperatures, and conditions suitable for beach activities come to the fore, while sea water temperature generally does not drop below 22°C throughout the year.
While Chaves and Santa Monica beaches stand out with light-colored sands extending for kilometers, the Viana Desert in the interior gives the island an appearance almost reminiscent of the moon's surface. Sal Island offers more facilities and water sports options; Boa Vista is suitable for those seeking a wider, quieter, and less developed coastal experience.
Best time: November; conditions get stronger towards December for wind sports.
Four details when choosing a warm route in autumn
- Clarify the month. A Mediterranean island that is perfect for September may not offer the same swimming conditions in November. The Canary Islands, Red Sea, Oman, and Cabo Verde are safer options for November trips.
- Look at sea temperature, not just weather. A sunny day does not always mean a warm sea. Especially on the coasts of the Atlantic Ocean, even if the weather is mild, the water may be cooler.
- Check whether the season is open. In small Greek islands and Mediterranean coastal towns, hotels, restaurants, and boat operators may change their working schedule starting in October.
- Do not build the single plan on the beach. The best routes in autumn are destinations that add a second strong experience alongside the sea, such as hiking, gastronomy, culture, or diving.
Frequently asked questions
Where to swim in October?
The southern coasts of Antalya, Crete, Cyprus, and Malta can be evaluated, especially in the first half of October. As the month progresses, the Canary Islands, Red Sea, and Oman turn into stronger options.
Where to go for a warm sea holiday in November?
In November, Marsa Alam and Red Sea coasts, Oman, the Canary Islands, and Cabo Verde stand out. Although mild days can be seen in Gozo and Cyprus, it is necessary to make a flexible program instead of guaranteeing a sea holiday.
What is the warmest route in Europe in autumn?
Cyprus, Crete, and Malta in October; and the Canary Islands, which are geographically close to the African coast, in November are among the strongest sun routes connected to Europe.
What is the advantage of an autumn sea holiday?
Lower visitor density, balanced temperatures compared to mid-summer, and the opportunity to combine nature or culture trips with the beach are the most important advantages. In contrast, current weather conditions and seasonal businesses must definitely be checked.
To extend summer, it is not always necessary to go further away; sometimes a few latitudes, sometimes changing the travel date by two weeks is enough. The good thing about autumn is right here: While sun and sea continue on the shores where crowds have receded, routes begin to show their real characters that go unnoticed during the summer months.
