The Meltemi, the northwest wind, which blows from the middle of May and can reduce the sensation of heat, is felt mostly on the west side of the island. There can be periods when the wind slows down, and the heat becomes intense, with highs around 35 °C (95 °F), though they are rare: usually, the temperature remains around 28/30 °C (82/86 °F). The highest record is 39 °C (102.2 °F) and was set in late June 2007.
Autumn, from mid-September to November, is often pleasantly warm and sunny at the beginning, and then becomes gradually milder and also more rainy.

In May, not only the sea is still a bit cold, but also the air can be cool for sunbathing, at least during some days.
For walks on the island, you can choose spring, in April and May, since summer can be very hot (although, as previously mentioned, periods of very hot weather are rare). You can also choose autumn, although it is rainier.
