Warm days, with room for hotter spells

Plan for summer clothing during the day, but do not assume every afternoon will feel the same. The warmer end of June can reach 30.4°C or more, so loose clothes, a hat and a slower pace around midday make sense. With humidity averaging 68%, shade may feel particularly welcome when temperatures climb. Put longer walks earlier in the day rather than making the hottest hours your busiest. Evenings are generally much milder than afternoons, which makes sitting outside more appealing if you dislike lingering heat. A light layer is still useful, especially if you tend to feel cool once the sun goes down.

Swimming is possible, but the sea has a cool edge

The sea is the main qualification to June's summer feel. At an average 21.7°C, it falls in the bracing range, so getting in may be less comfortable than the warm air suggests. The year-to-year range of 20°C to 23°C also means your experience can vary: some Junes offer a more inviting swim than others. If you enjoy cooler water, swimming is a reasonable part of the plan. If you prefer to linger in warm water, do not make that your deciding reason to go. Keep something dry to put on afterwards, particularly when a swim runs into the cooler evening.

Plenty of sunshine, but keep plans flexible

June offers about 9.9 hours of sunshine within 15.2 hours of daylight, giving you plenty of scope to spend time outside without cramming everything into midday. That long daylight window is useful for moving walks to cooler parts of the day. Rain is still a realistic interruption, with about 7 rainy days during the month, so a completely dry stay is not something to count on. Pack a light waterproof and leave some flexibility in outdoor plans. The balance favours sunshine, but the monthly figures do not tell you how rain will fall during your particular visit or how long any wet spell will last.
