The island is very close to the mainland, to which it is connected by a bridge. In the interior there are hills and low mountains, which culminate in Mount Stavrota, 1,158 metres (3,799 feet) high. Given the amount of rainfall, the island is green, despite the summer drought, and it's covered with forests.

Winter, from December to mid-March, is mild and rainy: there is a moderate amount of sunny days, but they alternate with periods of bad weather, with rains even abundant. Sometimes a cold wind from the north can blow, and in the coldest nights, light frosts can occur in the plain.

Spring, from mid-March to May, is mild; the rains become gradually rarer, and fine weather becomes more and more frequent. May is a good month, before the summer heat.

Summer, from June to mid-September, is hot and sunny; the maximum temperature normally fluctuates around 30 °C (86 °F), but sometimes it can reach 35/37 °C (95/99 °F). Luckily, sea breezes blow, and in any case you can cool yourself down in the sea.

Autumn, from mid-September to November, is mild (initially even quite warm) and rainy. In October there can still be sunny days, but the rains are quite abundant, and can also occur in the form of thunderstorms.
