Warm enough for summer clothes, without constant heat

Expect summer clothing to work well during the day, though June does not deliver strong heat throughout. Days reach 25°C about 42% of the time, while the warmer end of the month’s weather can bring 28.3°C or more. That makes June a sensible choice if you like eating outdoors and spending time on foot but do not want every afternoon shaped around avoiding heat. Humidity averages 76%, so warmer spells may feel sticky rather than crisp. Keep strenuous plans away from midday when it feels hot, and pack breathable clothes rather than assuming the average temperature tells the whole story.

Plenty of daylight, but leave room for rain

June gives you long days to work with: about 15.2 hours of daylight and 8.4 hours of sunshine daily. That leaves plenty of scope to shift outdoor plans into the brighter parts of the day, but sunshine is not continuous. There are about 8 rainy days, so a completely dry stay is not something to count on. Bring a light waterproof and shoes you would be happy wearing in rain, rather than packing only for the beach. If uninterrupted sunshine is your main requirement, June’s wet-weather risk is a meaningful drawback; if you can rearrange your days, it is easier to accommodate.

The sea is cooler than the air suggests

Swimming is the main reason to temper expectations. The average sea temperature is 21.1°C, with a year-to-year range of 20°C to 22°C, so the water is better described as bracing than warm. It may suit you if you enjoy a refreshing dip, but it is less appealing if your holiday depends on lingering comfortably in the sea. Warm air does not remove that initial chill, so judge swimming separately from sunbathing weather. Bring something dry to put on afterwards, especially if you stay out into the evening. For a trip combining outdoor time with optional swims, the balance is more favourable.
