Warm days, with layers for the evening

Daytime warmth should make walking and eating outdoors appealing when conditions are dry, but pack for variation rather than permanent sunshine. Only 16% of days reach 25°C, so a hot afternoon is a bonus, not something to build the trip around. On the warmest days, lighter clothing and a shaded break at midday will still be useful. After sunset, a jumper or light jacket makes more sense than relying on summer clothes alone. The coldest nights can fall to around 12°C or below. This is a good month if you prefer being active in moderate warmth; it is less convincing if your main aim is to lie in strong heat.

Keep swimming optional and plans flexible

The sea averages 20.9°C, which puts it in bracing rather than comfortably warm swimming territory. If you enjoy cooler water, a dip may be appealing, but anyone who dislikes the initial chill should avoid making swimming the centre of the holiday. Have something dry and warm ready afterwards. On land, about 5.7 hours of sunshine within 10.9 hours of daylight leaves scope for time outdoors, though not an expectation of clear skies all day. Around 8 rainy days means a light waterproof is worth packing and outdoor plans should be movable. Give yourself room to use dry spells for longer outings rather than fixing every day around the beach. October works better with that flexibility than with a sunshine-only itinerary.
