September doesn’t have to mean the end of your diving season. In fact, as the summer crowds begin to thin out, it can be one of the best times of year to plan a warm-water dive trip.
From tropical reefs and clear blue water to pelagic encounters and colourful marine life, there are plenty of destinations where September still delivers excellent diving conditions. Whether you’re looking for a last-minute escape, a long weekend of diving or a proper end-of-summer adventure, these destinations are worth keeping on your radar.
In this blog:
Malta & Gozo — Clear Mediterranean Diving
If you want warm water without travelling too far, Malta and Gozo are a great September option.
The Mediterranean is still warm after the peak summer months, while the busiest holiday period starts to wind down. September can offer excellent visibility, calm conditions and comfortable temperatures for exploring reefs, caves, wrecks and dramatic underwater landscapes.
Gozo is particularly popular with divers looking for a more relaxed atmosphere, with sites such as the Blue Hole offering some of the Mediterranean’s most recognisable underwater scenery.
- Best for: Wrecks, caves, reefs and Mediterranean diving
- Why September: Warm water, good visibility and fewer peak-season crowds
Red Sea, Egypt — Warm Water & World-Class Reefs
The Red Sea is one of the safest bets for warm-water diving in September.
Water temperatures remain comfortably tropical, visibility can be excellent and there is an enormous variety of diving to choose from. Sharm El Sheikh, Hurghada and Marsa Alam all offer access to colourful reefs, dramatic walls and abundant marine life.
September is also a great time to consider a Red Sea liveaboard if you want to spend several days diving some of the region's more remote sites.
- Best for: Reefs, walls, wrecks, liveaboards and big marine life
- Why September: Hot, warm water and excellent diving conditions
Cyprus — Wrecks, Reefs & Warm Mediterranean Water
Cyprus is another Mediterranean destination that remains firmly in diving season during September.
The island is famous for the Zenobia, one of the world's best-known recreational dive wrecks. Sitting just offshore from Larnaca, the enormous ferry offers multiple dives and plenty to explore.
Away from the wreck, Cyprus also has reefs, caves and interesting marine life, making it a good choice if you want a mixture of diving rather than spending your entire trip on one type of site.
- Best for: Wreck diving and Mediterranean exploration
- Why September: Warm seas and long summer conditions
The Canary Islands — Year-Round Diving
For divers looking for a European destination with a longer diving season, the Canary Islands are difficult to beat.
Tenerife, Lanzarote, Gran Canaria and Fuerteventura all offer different underwater environments, from volcanic rock formations and caves to reefs and wrecks.
September brings warm conditions both above and below the surface, and the islands are well suited to divers who want to combine diving with a proper holiday.
- Best for: Volcanic landscapes, reefs and varied diving
- Why September: Warm water and reliable diving conditions
The Philippines — Tropical Diving Beyond Summer
If you’re willing to travel further, September can still be a fantastic month for diving in parts of the Philippines.
The country is home to an enormous variety of dive destinations, from macro-rich reefs and thresher sharks to coral gardens and wrecks. Conditions do vary considerably between regions during the wet season, so choosing the right destination is important.
Malapascua, for example, remains famous for regular thresher shark encounters, while other parts of the country can offer excellent diving depending on local weather and sea conditions.
- Best for: Sharks, macro life, coral reefs and tropical diving
- Why September: Warm water year-round, with destination-specific conditions to consider
Indonesia — Pick the Right Region
Indonesia is another destination where September can offer outstanding diving, but location matters.
Some areas experience particularly favourable conditions around this time of year, making September a popular month for divers heading to destinations such as Komodo.
Komodo is famous for dramatic underwater scenery, strong currents and an incredible variety of marine life. It’s an excellent choice for experienced divers looking for something more adventurous.
- Best for: Currents, pelagics, reefs and experienced divers
- Why September: Excellent conditions in several key dive regions
Bali — Easy Diving With Plenty to Explore
Bali is another strong option for a September getaway, particularly if you want a combination of diving and a wider holiday.
The island offers a huge variety of sites, from the famous USAT Liberty wreck at Tulamben to coral reefs, muck diving and encounters with larger marine life.
September can also be a good compromise between the busiest holiday period and the wetter months later in the year.
- Best for: Wrecks, reefs, macro life and mixed-level dive trips
- Why September: Generally favourable conditions and plenty of dive options
So, Where Should You Go?
The best September destination depends on what you want from your trip.
For easy European access, look towards Malta, Gozo, Cyprus or the Canary Islands.
For consistently warm tropical diving, the Red Sea is hard to beat.
For sharks and tropical marine life, the Philippines is well worth considering.
And if you're an experienced diver looking for something more adventurous, Indonesia can deliver some seriously memorable diving.
September is also a great time to book a trip if you prefer quieter dive sites and a more relaxed atmosphere. The peak summer rush is starting to disappear, but many warm-water destinations are still firmly in their diving season.
So don't pack away your dive gear just yet. Summer might be winding down, but the diving doesn't have to.

FAQs
Is September a good month to dive in the Mediterranean?
Yes. Water temperatures are typically still warm from summer, visibility is often excellent, and peak-season crowds have usually started to ease off, making it one of the best months to dive Malta, Gozo or Cyprus.
Do I need a wetsuit for September diving?
It depends on the destination. Mediterranean and Canary Islands water can still feel comfortably warm in a 5mm wetsuit, while Red Sea, Philippines, Indonesia and Bali diving is typically fine in a 3mm, depending on personal cold tolerance.
Which September destination is best for beginners?
The Red Sea and Bali are both strong choices for newer divers, offering warm water, good visibility and a wide range of easier sites alongside more advanced diving for later in the trip.
Is September good for liveaboards?
Yes, particularly in the Red Sea, where September conditions suit multi-day liveaboard itineraries to more remote reef systems that aren't easily reached on day trips.
