Warm enough for summer clothes, not constant heat

Pack mainly light clothing, but leave space for a light layer for evenings. The average night is mild rather than cold, although cooler nights can fall to 16°C or below. Daytime warmth is fairly dependable, but sustained high heat is less so: 50% of days reach 25°C, while only 6% reach 30°C. That makes September a sensible fit if you like warmth but do not want every outing shaped around intense heat. Warmer days can still reach 29°C or more, so shade and a slower pace at midday may be welcome. If consistently hot afternoons are essential, the averages suggest keeping your expectations in check.

Good swimming conditions, with room for wet days

The sea is a strong reason to choose September. At 24°C on average, it is warm enough for swimming, and the year-to-year range of 23°C to 25°C stays on the comfortable side of the swimming threshold. There is also useful outdoor time, with about 7.7 hours of sunshine within 12.3 hours of daylight. The limitation is about 8 rainy days across the month, so avoid making every day's plans depend on dry weather. That figure does not mean each wet day is a washout, but it does justify bringing a light waterproof and leaving swimming plans flexible. Overall, this suits travellers happy to work around some rain in return for warm water and mild evenings.
