Winter: mild afternoons, cool nights and rain
December, January and February suit travellers happy to plan around the weather rather than spend every day by the sea. December and January average 16°C by day, so outdoor time can be comfortable with layers, but it is not summer clothing weather throughout the day. January nights fall to 8°C, making a warm outer layer useful after sunset. February edges up to 17°C, although the sea drops to 15°C and is likely to feel cold for casual swimming. December and January each average 8 rain days; carry a waterproof and keep plans flexible. Make the warmer part of the day your main window for being outside.
Spring into June: choose warmth or swimming
March and April are useful months for travellers who want to stay active without summer heat. Daytime averages rise from 19°C to 20°C, but showers remain part of the picture and evenings call for an extra layer. May brings a clearer shift towards beach weather, with 24°C afternoons and 9 hours of sunshine. Its 18°C sea is the catch: warm air does not yet mean warm swimming. June is the stronger compromise if sea time matters. Days average 28°C, the sea reaches 21°C and rain becomes much less frequent. Pack light clothes and sun protection, and move more energetic plans away from midday as the season warms.
Summer into autumn: heat eases, the sea cools slowly
July and August suit travellers who put dry, sunny beach days first. Both average 31°C by day and a 23°C sea, so shade and a slower pace at midday make sense. Nights stay warm too, especially in August at 21°C. September is the alternative if peak summer feels too hot: afternoons average 28°C and the sea remains at 22°C, though rain becomes more likely. October still offers 24°C days and a 20°C sea, but its 8 rain days make a beach-only plan less dependable. By November, daytime temperatures ease to 19°C and nights to 12°C. Bring layers and treat swimming as an optional extra rather than the focus of the trip; the sea has fallen to 18°C.
