Expect proper heat, not just warm afternoons
Pack for hot weather rather than a mild summer break. Around 47% of June days reach 30°C, while the hottest 10% reach 34°C or more, so the average does not tell the whole story. Put more active plans in the morning or later afternoon, and leave room for shade around midday. Light, loose clothing, sun protection and regular drinks make sense. Evenings are generally warm enough for light clothes, though a thin layer is useful if you feel the cold: the coolest 10% of nights fall to about 17°C or lower. June suits travellers comfortable with heat; it is less appealing if you prefer staying active throughout the day.
Dry weather and a sea ready for swimming
Rain is unlikely to shape most of your holiday, with about 3 rainy days across June. That supports making outdoor plans without building the trip around wet-weather alternatives, although a shower is still possible. Sunshine averages 12.8 hours within 14.5 hours of daylight, giving you plenty of scope to enjoy time outside away from the strongest midday heat. The sea averages 23.1°C, with a year-to-year range of 22°C to 24°C, so swimming is a reasonable expectation rather than something reserved for hardy swimmers. This combination makes June particularly suitable if your main aim is swimming and relaxing outdoors, provided you are happy to take shade breaks.
