Winter, from December to mid-March, is quite mild, even though it is not as mild as on the southern islands of Greece; moreover, it is rainy, especially in December and January; during some years, the rains are plentiful. However, there is a moderate amount of sunny days too. Sometimes, there may be outbreaks of cold air from the Balkan Peninsula, with some cold and windy days, and possible slight frosts at night. In inland hills, it can even snow.
Spring, from mid-March to May, is mild; the rains are quite frequent at the beginning, but then, they gradually become rarer, and fine weather becomes more and more frequent. May is a good month, before the summer heat.
Summer, from June to August, is hot and sunny: the maximum temperature reaches 35 °C (95 °F) with some frequency, and during heat waves, in the worst moments it can reach 40/42 °C (104/108 °F). Luckily, sea breezes blow, providing relief, at least when the heat is not excessive, and in any case, you can cool yourself in the sea. This part of Greece, overlooking the Ionian Sea, is outside the area where the annoying but cooling Meltemi blows; as a consequence, here, the sea is warmer (see below).
Autumn, from September to November, is mild (initially even quite hot) and rainy. In September, there may still be many sunny days.
The amount of sunshine in Corfu is great in summer, when blue skies prevail, but it is also good in spring, when days with clear skies are already frequent. On the contrary, from October to March, sunny days alternate with periods of bad weather. Here are the average sunshine hours per day.

Best Time
The best time to go to Corfu for a beach holiday runs from June to August, although the weather is often good also in the first half of September.
If you plan to go hiking and walking across the island, you can go from mid-April to mid-June, in order to avoid the heat that can occur in high summer.
