Cyprus, Bodrum, and Zanzibar are the most reliably hot destinations in September, with average temperatures of 26–33°C and dry, sunny conditions holding through the month. Sardinia, Menorca, Puglia, Dubrovnik, Lake Garda, Madeira, and Split round out this list with warm, quieter alternatives as the Mediterranean’s peak-season crowds thin out.

    Where is hot in September comes down to picking a destination that benefits from the shoulder season rather than fighting it: the Mediterranean cools only slightly from August, East Africa’s Zanzibar sits at the heart of its dry season, and almost everywhere on this list gets noticeably calmer and cheaper than a month earlier.

    This list covers 10 hot destinations in September, why each one works this specific month, what the heat actually feels like, and what to know before booking

    Top 10 Hot Destinations Ranked

    1. Cyprus

    Cyprus is the hottest and driest destination on this list in September, holding onto its summer peak while resort crowds thin out noticeably from August. Nissi Beach, the Akamas Peninsula, and the Troodos foothill wine routes all feel calmer this month than a few weeks earlier.

    The heat is dry and intense, with very low humidity that makes the high numbers more manageable than they sound.

    Average temperature in Cyprus in September runs 29-33°C (84-91°F), with 12 hours of daily sunshine. Humidity averages 50%.

    Cyprus is an EU member but not in the Schengen Area, and counts stay-time separately.

    Best time to visit Cyprus is May through October, and September sits right at the point where August’s peak pricing has eased without the weather changing.

    2. Sardinia, Italy

    September is when Sardinia becomes genuinely accessible again. Italian domestic visitors return home after the mid-August Ferragosto holiday, leaving the Costa Smeralda’s white-sand beaches and the Gulf of Orosei’s sea caves far quieter than a month earlier.

    The heat is warm rather than intense, softened by Tyrrhenian sea breezes along the coast.

    Average temperature in Sardinia in September runs 26-28°C (79-82°F), with 8 hours of daily sunshine. Humidity averages 60%.

    Best time to visit Sardinia is May through June and September through October, avoiding both the crowds and the sharpest heat of July and August. If you’re exploring beyond the coast, our guide to 25 best places to visit in Italy beyond the tourist trail covers more of the island’s quieter inland towns alongside the rest of the country.

    3. Menorca, Spain

    Menorca’s UNESCO Biosphere Reserve status has kept it free of the mass-resort development found on its larger neighbors, and September lets its hidden coves breathe without August’s car-park queues. Cala Macarella and the Talatí de Dalt prehistoric site are both easier to enjoy this month.

    The heat is warm and Mediterranean, tempered by the island’s characteristic breeze.

    Average temperature in Menorca in September runs 24-28°C (75-82°F), with 8 hours of daily sunshine. Humidity averages 62%.

    Best time to visit Menorca is June and September, bracketing the busiest July-August stretch, as our guide to the best time to visit Spain covers in more detail. See our wider list of best places to visit in Spain if Menorca is one stop on a longer Balearic trip.

    4. Zanzibar, Tanzania

    September sits at the heart of Zanzibar’s dry season, running from June through October, which brings the clearest water of the year to Nungwi and Kendwa beaches and the best visibility for snorkeling trips to Mnemba Atoll.

    The heat is tropical and humid, tempered by a steady Indian Ocean breeze.

    Average temperature in Zanzibar in September runs 26-30°C (79-86°F), with 8 hours of daily sunshine. Humidity averages 73%.

    Best time to visit Zanzibar is June through October, and September sits comfortably in the middle of that dry stretch. Most non-East African nationals need a Tanzania e-visa arranged before travel, and since October 2024, Zanzibar has required a separate mandatory travel insurance policy from the Zanzibar Insurance Corporation (ZIC), bought in advance — standard travel insurance from home isn’t accepted in its place.

    5. Bodrum, Turkey

    Bodrum holds onto summer heat well into September, while Turkey’s exchange rate keeps resort stays meaningfully cheaper than Mediterranean equivalents at a similar temperature. Gümüşlük’s fishing-village waterfront and gulet sailing trips through the Aegean’s hidden coves are both at their best once the peak crowds ease.

    The heat is warm and fairly dry, cooled by Aegean sea breezes.

    Average temperature in Bodrum in September runs 28-32°C (82-90°F), with 10-11 hours of daily sunshine. Humidity averages 58%.

    Best time to visit Bodrum is May through June and September through October. For more on the country beyond the coast, see our fun facts about Turkey.

    Stay connected in Bodrum with a Turkey eSIM, useful for gulet-trip bookings and navigating between Bodrum town and the surrounding bays.

    6. Puglia, Italy

    September trades July’s punishing Adriatic heat for something far more walkable, which is when Polignano a Mare’s clifftop streets and Alberobello’s trulli houses are genuinely enjoyable to explore on foot.

    The heat is warm and mild by Italian summer standards, with sea breezes along the Salento coast.

    Average temperature in Puglia in September runs 25-28°C (77-82°F), with 8 hours of daily sunshine. Humidity averages 65%.

    Best time to visit Puglia is May through June and September through October. Our guide to things to do in Italy covers more of the region’s hill towns and coastal villages if you’re combining Puglia with other stops.

    Stay connected in Puglia with an Italy eSIM, useful for driving between the region’s hill towns and coastal villages.

    7. Dubrovnik, Croatia

    September is when Dubrovnik stops being a cruise-ship bottleneck and becomes the walled city it’s actually meant to feel like. Cruise arrivals drop sharply after the summer peak, which loosens up the Old Town’s Stradun and the medieval wall walk noticeably.

    The heat is warm Mediterranean, cooled by a light Adriatic breeze.

    Average temperature in Dubrovnik in September runs 25-28°C (77-82°F), with 8-9 hours of daily sunshine. Humidity averages 62%.

    Best time to visit Dubrovnik is May through June and September through October.

    Stay connected in Dubrovnik with a Croatia eSIM, useful for the ferry crossing out to the Elafiti Islands.

    8. Lake Garda, Italy

    September keeps Lake Garda’s water warm enough for swimming while clearing out the Italian domestic holiday crowds that fill Sirmione and Riva del Garda through August.

    The heat is mild and lake-moderated, cooler than the coastal destinations on this list.

    Average temperature at Lake Garda in September runs 22-26°C (72-79°F), with 7-8 hours of daily sunshine. Humidity averages 68%.

    Best time to visit Lake Garda is May through June and September, when the lake stays warm without peak crowds. Our Italy travel guide covers how Lake Garda fits into a wider trip through the country’s interior.

    Stay connected at Lake Garda with an Italy eSIM, useful for the ferry network linking the lake’s towns.

    9. Madeira, Portugal

    Madeira runs warm and pleasant close to year-round rather than hot, and September adds nothing dramatic beyond steady, comfortable conditions for the levada walking trails through the island’s laurel forest.

    The heat is mild Atlantic warmth rather than intense sun.

    Average temperature in Madeira in September runs 23-26°C (73-79°F), with 6-7 hours of daily sunshine. Humidity averages 70%.

    Best time to visit Madeira runs nearly year-round, as our guide to the best time to visit Portugal sets out, though September avoids both winter rain and summer crowds. See things to do in Portugal for more beyond Madeira itself.

    Stay connected in Madeira with a Portugal eSIM, useful for navigating between Funchal and the levada trailheads.

    10. Split, Croatia

    Split works as a calmer, more practical base than Dubrovnik in September, with easy ferry access to Hvar, Brač and Vis once the August superyacht crowd has moved on. Croatia joined the Schengen Area in January 2023, so standard Schengen passport validity rules apply here.

    The heat is warm Adriatic, with clear water ideal for snorkeling.

    Average temperature in Split in September runs 25-27°C (77-81°F), with 8 hours of daily sunshine. Humidity averages 60%.

    Best time to visit Split is May through June and September through October.

    Stay connected in Split with a Croatia eSIM, useful for island-hopping without needing a new SIM at each stop.

    Before You Go: Practical Tips for September Travel

    1. Book Zanzibar’s dry-season window early, since September overlaps with its most popular diving and snorkeling conditions.
    2. Pack a light layer for Lake Garda and Madeira’s cooler evenings, even on an otherwise warm-weather trip.
    3. Bring reef-safe sunscreen for Zanzibar and Bodrum’s coastal destinations.
    4. Confirm Zanzibar’s entry requirements early: both the Tanzania e-visa and the separate, mandatory ZIC travel insurance need arranging before departure, and standard travel insurance from home won’t cover the ZIC requirement.
    5. Book ferry crossings between Split, Dubrovnik and the Croatian islands ahead, as September schedules can thin out compared to peak summer.
    6. If you’re new to long-haul travel, our travel tips for first-time flyers cover the basics worth knowing before heading to Zanzibar.
