You can bring a sweatshirt for cool evenings, which occur mainly in June, but in windy periods, those who are sensitive to cold may feel a little cool also in July and August.
In May, not only the sea is still a bit cold, but also the air can be cool for sunbathing, at least on certain days.
If you want to visit cities or to go on excursions on the island, you can choose spring, in April and May, since in summer it can be hot (though quite rarely). You can also choose autumn, at least in September and October, while later the rains increase.
