Hot days, warm seas and little overnight cooling

The heat is consistent rather than frequently extreme: only 6% of days reach 30°C, but humidity averages 77%, so the temperature alone does not tell the whole comfort story. Plan active outings for earlier in the day and leave midday for shade or a swim. The sea averages around 28°C, making June well suited to travellers who dislike a chilly dip. Pack loose, lightweight clothes and check that your accommodation offers cooling you will be comfortable sleeping with. Nights average around 26°C, so evenings are not much of a break from the daytime warmth. If sticky nights bother you, that is a more useful consideration than the daytime high.

Allow for rain without writing off outdoor time

June is a wet month, but it still averages about 5.8 hours of sunshine within 13 hours of daylight. That leaves scope for time outdoors, without promising clear skies throughout the day. Rain on about 13 days makes a flexible schedule more sensible than packing every day with weather-dependent plans. It does not mean those days are complete washouts, though you should not assume the rain will always be brief either. Take a light waterproof and keep anything that needs to stay dry protected. June suits travellers happy to work around mixed conditions; it is a less convincing choice if uninterrupted sunshine is the main reason for the trip.
