Reliable warmth, but keep midday plans flexible

September is a good fit if you want warmth you can usually count on: 90% of days reach 25°C. Temperatures reach 30°C on 8% of days, so that level of heat is possible rather than typical. With humidity at 72%, conditions may feel muggy, particularly if you are active. Pack lightweight clothes and keep more energetic plans for the cooler parts of the day, leaving room for shade breaks around midday. Evenings generally call for light clothing rather than a heavy layer, given the average night low of 22°C. If cool sleeping conditions matter to you, check that your accommodation has air conditioning.

Good swimming weather with little rain to work around

The sea averages 23.2°C, making September a sensible choice if swimming is central to your holiday rather than an occasional possibility. Its year-to-year range of 22°C to 24°C stays within comfortable swimming territory, though your own tolerance will matter. There are about 2 rainy days in the month, so rain is unlikely to dictate your itinerary, but a completely dry stay is not guaranteed. Around 9.1 hours of sunshine a day gives you plenty of scope for outdoor time without packing everything into midday. Bring sun protection and leave your schedule flexible enough to take a break when the heat feels tiring.
