Where is hot in September: best destinations for UK travellers

September is one of the finest months to travel for sun, and the Met Office confirms that southern European and Mediterranean destinations consistently deliver warm, reliable weather well into autumn. Seas are at their warmest after a full summer of solar absorption, crowds thin out as schools return, and prices drop noticeably from their August peak. Based on climate reliability, sea temperature, flight time from the UK, and value signals, here are the top picks for where is hot in September:

• Cyprus — daytime highs around typical warm temperatures, crystal-clear seas that are enjoyably warm, and virtually no rain
• Crete and the Greek islands — warm days, long sunshine hours, and a quieter, more authentic atmosphere than July
• Canary Islands (Tenerife, Gran Canaria, Lanzarote) — year-round warm weather with reliable Atlantic breezes
• Malta — warm days, exceptional sea clarity, and short 3-hour flights from the UK
• Algarve, Portugal — pleasantly warm with Atlantic-cooled evenings, ideal for families and couples
• Antalya, Turkey — very warm days and seas, with outstanding all-inclusive value
• Hurghada and Marsa Alam, Egypt — very hot weather, zero rainfall, and world-class Red Sea diving
• Dubai, UAE — very hot weather suitable for travellers seeking extreme heat and luxury infrastructure

Always check Gov for your chosen destination before booking.

Key takeaways

September delivers warm seas, reliable sunshine, and better value than August across the Mediterranean, North Africa, and the Gulf — making it one of the strongest months of the year for a sun holiday from the UK.

How do these September destinations compare at a glance?

The table below draws on Post Office temperature and sea-temperature guidance and JetpacGlobal’s September beach holiday data to give you consistent metrics across every destination.

Seasonal risk note: The Caribbean sits within Atlantic hurricane season through September, so it carries elevated storm risk. NG Cruise’s September cruise analysis confirms that Mediterranean cruises are generally lower risk, while Caribbean routes require flexible booking and careful insurance cover. Always verify conditions via GOV.UK travel advice before committing.

One detail worth highlighting: sea temperatures are typically at their annual peak in September. The Met Office explains that seas absorb heat throughout summer and retain it into early autumn, which is why September swimming is often warmer than July.

Why September is one of the best months to travel for sun

September is a genuine shoulder-season sweet spot. Schools have returned, the peak-summer rush has cleared, and the weather across the Mediterranean and beyond remains outstanding.

• Fewer crowds — popular beaches, restaurants, and historic sites are noticeably quieter after the August peak
• Lower prices — flights and accommodation typically drop in cost once school holidays end
• Warmest seas of the year — sea temperatures peak in late summer and hold through September
• More comfortable daytime heat — the intense August heat eases slightly, making sightseeing and outdoor activities more enjoyable
• Longer daylight hours — September still offers 12–13 hours of daylight across southern Europe
• Richer local atmosphere — with fewer tourists, local life reasserts itself: markets, festivals, and restaurants feel more authentic

Pro Tip: Book flights for Tuesday or Wednesday departures and target the first two weeks of September for the best combination of warm weather and post-peak pricing. Flexible-date searches on UK carriers such as Jet2 and TUI often reveal significant savings of £50–£100 per person compared with weekend departures.

The best European and Mediterranean destinations in September

Cyprus

Cyprus is arguably the most reliably hot European destination in September, with daytime temperatures around 30°C, up to 11 hours of sunshine, and sea temperatures near 27°C. Rainfall is almost non-existent. Flights from UK airports take roughly 4.5 hours, and the island’s resort areas — Paphos, Limassol, Ayia Napa — cater brilliantly to both families and couples. September brings the Limassol Wine Festival, a wonderful reason to visit beyond the beach.

Best for: couples, beach holidays, families seeking reliable heat

Crete and the Greek islands (including Santorini)

Crete offers 28°C days, 9–10 hours of sunshine, and seas around 25°C in September, all with noticeably thinner crowds than August. The island’s sheer size means you can find genuinely quiet corners even in peak season, and September is when the local tavernas feel most relaxed. Santorini sits slightly cooler at 27°C but remains stunning for couples, with the caldera views arguably best appreciated without summer’s shoulder-to-shoulder crowds. Flights to both take around 3.5 hours from major UK airports.

Best for: Crete — families and culture seekers; Santorini — romantic couples

Malta

Three hours from the UK and with sea temperatures around 26°C, Malta punches well above its size. The island’s history is extraordinary — the Valletta waterfront, the ancient temples, the walled city of Mdina — and September’s 28°C days make exploring genuinely pleasant rather than exhausting. Prices drop after August, making it one of the better-value Mediterranean options for short breaks.

Best for: culture lovers, couples, value-conscious travellers

Algarve, Portugal

The Algarve delivers 26°C days and around 8–9 sunshine hours in September, with Atlantic breezes keeping evenings comfortable. Sea temperatures sit around 22°C — cooler than the eastern Mediterranean but still very swimmable. It’s a 2.5-hour flight from the UK, which makes it ideal for shorter breaks. The dramatic golden cliffs of Praia da Marinha and the family-friendly resort of Albufeira are both at their best once the August crowds clear.

Best for: families, golfers, couples wanting a short-haul escape

Sicily

Sicily’s food and culture alone justify the trip, and September adds near-perfect weather: 28°C days, 9 hours of sunshine, and seas around 25°C. The harvest season kicks in during September, meaning local markets overflow with figs, grapes, and almonds. Flights take roughly 2.5 hours from UK airports. Taormina, with its ancient Greek theatre overlooking the sea, is particularly magical in September’s softer light.

Best for: food and culture lovers, couples

Puglia and the Amalfi Coast

Southern Italy’s two great September draws sit at opposite ends of the style spectrum. Puglia — the heel of Italy’s boot — offers whitewashed trulli villages, long sandy beaches, and exceptional local cuisine at prices well below the Amalfi Coast. The Amalfi Coast itself is dramatic and romantic, with cliffside villages and turquoise waters, though it remains pricier and busier. Both enjoy 28°C days and 9 hours of sunshine. Flights to Bari (for Puglia) or Naples (for Amalfi) take around 2.5 hours.

Best for: Puglia — value-seeking couples and foodies; Amalfi — luxury-minded couples

Mallorca and Menorca

The Balearics hold their warmth well into September, with 27°C days and seas around 24°C. Mallorca suits those who want variety: the buzzing resort strips of Magaluf and Alcúdia alongside the quieter mountain villages of the Tramuntana. Menorca is the calmer, more family-friendly alternative, with some of the clearest water in the Mediterranean. Both are around 2 hours from UK airports.

Best for: Mallorca — mixed groups and couples; Menorca — families

Sardinia

Sardinia’s beaches are among the finest in Europe, and September is when they truly shine: 27°C days, 9 hours of sunshine, and seas around 25°C, with the August crowds gone. The Costa Smeralda remains glamorous but quieter, while the south’s beaches around Villasimius offer extraordinary water clarity. Flights take roughly 2.5 hours.

Best for: beach lovers, couples, those seeking natural beauty

Dubrovnik and Split, Croatia

Croatia’s Dalmatian coast is stunning in September, with 26°C days and seas around 24°C. Dubrovnik’s famous Old City walls are far more enjoyable to walk without the summer cruise-ship crowds, and Split’s Diocletian’s Palace is one of the most remarkable ancient sites in Europe. Flights take around 2.5 hours, and September prices are noticeably lower than August.

Best for: culture lovers, couples, history enthusiasts

Tenerife and the Canary Islands

The Canaries occupy a unique position: they’re warm year-round, making them reliable even if September brings slightly more cloud than the eastern Mediterranean. Tenerife averages 27°C, Gran Canaria is slightly sunnier, and Lanzarote’s volcanic landscape offers something genuinely different. The European Commission recognises the Canary Islands as outermost regions with distinct microclimates, and UNESCO’s biosphere designation for Fuerteventura reflects the archipelago’s exceptional natural environment. Flights take around 4 hours.

Best for: families, year-round reliability, nature lovers

North Africa, the Red Sea, and the Gulf in September

Egypt: Hurghada and Marsa Alam

Egypt’s Red Sea coast is one of the most reliably hot and dry destinations on the planet in September. Hurghada averages 34°C with zero rainfall and 11–12 hours of sunshine. Sea temperatures sit around 28°C, making the Red Sea’s coral reefs exceptional for snorkelling and diving. Marsa Alam, further south, is quieter and attracts serious divers. Flights from the UK take around 5 hours.

• Zero rainfall in September — genuinely guaranteed sunshine
• Red Sea visibility is outstanding in September, with warm, calm water
• All-inclusive resorts offer strong value compared with Mediterranean equivalents

Best for: divers, sun seekers, value-conscious all-inclusive travellers

Turkey: Antalya and the Turkish Riviera

Antalya and the broader Turkish Riviera deliver some of the highest temperatures in the Mediterranean in September: 32°C days, 11 hours of sunshine, and seas around 27°C. The Turquoise Coast around Bodrum and Marmaris is equally impressive. Turkey’s all-inclusive resorts are among the best-value in the region, and the country’s history — Ephesus, Pamukkale, Cappadocia — rewards those who venture beyond the beach. Flights take around 4 hours.

Best for: all-inclusive families and couples, history enthusiasts

Pro Tip: Always check the GOV.UK travel advice page for Turkey before booking, particularly regarding entry requirements and regional travel advisories. The Travel Aware campaign also provides useful pre-departure sun-safety and health guidance for high-heat destinations.

Dubai and the UAE

Dubai in September is genuinely extreme: 38°C days, zero rain, and sea temperatures around 31°C. It’s not for everyone, but for those who want uncompromising heat, world-class shopping, and luxury resorts with powerful air conditioning, it delivers. The IATA flight connectivity data reflects Dubai’s status as one of the world’s best-connected hubs, with multiple daily direct flights from UK airports taking around 7 hours. September also marks the start of Dubai’s shoulder season, so hotel rates begin to ease.

Best for: luxury travellers, long-haul seekers, those who want extreme heat

How to choose the right September sun holiday for your priorities

The decision rule is straightforward: prioritise sea temperature first, then rainfall risk, then flight time, then price. Here’s how to apply it:

1. Check historical sea temperatures — warmer seas (above 24°C) make swimming genuinely enjoyable; Cyprus, Turkey, and Egypt lead here
2. Assess rainfall risk — Egypt and the Canaries are virtually rain-free; the Algarve and Croatia carry slightly more risk of a rainy day
3. Match flight time to holiday length — for a long weekend or 5-night break, stick to under 3 hours (Malta, Algarve, Sicily); for a week or more, Turkey and Egypt offer excellent value for the extra flight time
4. Consider local events and infrastructure — September festivals (Limassol Wine Festival, Venetian Night in Dubrovnik) can genuinely enhance a trip
5. Check travel advice and insurance — verify GOV.UK foreign travel advice and confirm your travel insurance covers medical costs in your chosen destination

Three questions to narrow your choice quickly:

• Do you prioritise warm sea swimming above everything else? Choose Cyprus, Turkey, or Egypt.
• Is a short flight more important than extreme heat? Choose Malta, Algarve, or Sicily.
• Do you want culture alongside the beach? Choose Crete, Dubrovnik, or Sicily.

Red flags to avoid: destinations entering their rainy or monsoon season (South-East Asia’s monsoon peaks in September), the Caribbean during active hurricane season, and extremely high-heat destinations (Dubai, Egypt) if you’re travelling with very young children or elderly relatives who may struggle in 35°C+ heat.

Practical tips for booking and staying safe

• Book flights early — September demand from UK airports rises sharply after school holidays are confirmed; booking 3–6 months ahead secures the best fares
• Target mid-September departures — the first week of September can still carry peak-summer pricing; the second and third weeks often offer the best balance of warm weather and lower cost
• Pack for warm days and cooler evenings — Mediterranean evenings in September can drop to 18–20°C, so a light layer is worth packing
• Sun safety matters — even in September, UV levels remain high across the Mediterranean and Red Sea; use SPF 30+ and reapply after swimming
• Stay hydrated — in destinations above 30°C (Turkey, Egypt, Dubai), drink at least 2 litres of water daily and avoid prolonged midday sun exposure
• Travel insurance is non-negotiable — ensure your policy covers medical costs, cancellation, and any activities (diving, water sports) you plan to do
• Check airline baggage policies — UK carriers including Jet2, TUI, and easyJet each have different baggage allowances; confirm before you pack

Pro Tip: Request a room on a higher floor away from the pool and entertainment areas for quieter nights — a small detail that makes a significant difference on a relaxation holiday. Half-board or all-inclusive board basis in September often costs less than August equivalents, so it’s worth comparing board options at the time of booking.

Always consult the Travel Aware campaign for pre-departure health and safety guidance, and check the latest entry requirements on GOV.UK.

How we selected these destinations and which sources we used

Every destination in this guide was assessed against four filters:

• Sea temperature — checked against Post Office travel guidance and JetpacGlobal’s September beach holiday data

Primary sources used:

• Gov
• Post Office — September, October and November temperatures in Europe
• IATA — International Air Transport Association
• Travel Aware campaign

Temperature and sunshine figures represent typical seasonal averages. Actual conditions vary year to year, so always check up-to-date forecasts close to your travel dates.

Accommodation availability and booking tips for September travel

September is genuinely one of the best months to book. Availability is higher than August, prices are lower, and the best rooms — sea-view suites, adults-only pools, beachfront villas — are far easier to secure. That said, popular resorts in Cyprus, Crete, and Antalya still fill up quickly, particularly in the first two weeks of September when families squeeze in a final summer trip.

Book at least 3–4 months ahead for the best selection and pricing. If you’re flexible on dates, mid-September departures consistently offer the strongest value. All-inclusive board basis is worth comparing carefully: in Turkey and Egypt especially, September all-inclusive rates can represent outstanding value, often including drinks, entertainment, and water sports at no extra cost.

For self-catering or villa holidays in the Algarve, Mallorca, or Croatia, September is the prime month: owners often reduce rates after August, and the quieter roads and beaches make villa life genuinely relaxing. Check that your accommodation is ATOL-protected when booking a package, and confirm cancellation terms before paying a deposit.

Health and safety tips for warm-destination travel in September

High temperatures and strong UV levels remain a genuine risk across all the destinations in this guide, even in September. A few straightforward precautions make a significant difference.

Sun and heat protection:

• Apply SPF 30 or higher every morning and reapply every two hours, especially after swimming
• Wear a wide-brimmed hat and UV-protective sunglasses during peak sun hours (11am–3pm)
• In destinations above 32°C (Turkey, Egypt, Dubai), limit direct sun exposure between noon and 3pm

Hydration and food safety:

• Drink bottled or filtered water in Egypt and Turkey; tap water is generally safe in Cyprus, Malta, and EU destinations
• Be cautious with street food in very hot weather — food spoils faster in high temperatures

Medical and insurance preparation:

• Carry a European Health Insurance Card (EHIC) or its UK successor (GHIC) for EU and EEA destinations — it provides access to state healthcare at reduced or no cost
• Ensure your travel insurance covers the full cost of medical repatriation, not just treatment
• Pack any prescription medication in your hand luggage with a copy of the prescription

A travel adviser’s honest view on September sun holidays

September is the month I recommend most confidently to UK travellers who want genuine sun without the August chaos. The sea is warm, the resorts are quieter, and the value is noticeably better — yet the weather across the Mediterranean and beyond remains outstanding.

The destinations I find myself recommending most often depend entirely on the traveller. For families who want reliable heat and easy flights, Cyprus or Malta are hard to beat. Couples looking for something more atmospheric tend to gravitate towards Santorini or Dubrovnik in September, when those iconic spots finally breathe again. For those who want serious heat and exceptional value, Turkey’s Antalya region and Egypt’s Red Sea resorts consistently over-deliver.

The one piece of advice I’d give every traveller planning a September holiday: check the sea temperature before you book, not just the air temperature. A destination that’s 28°C in the air but only 20°C in the water is a very different experience from one where both figures are in the mid-to-high twenties. September is when that distinction matters most, because swimming is often the centrepiece of the holiday.
