The rains are quite abundant, in fact they amount to nearly 1,100 millimeters (43 inches) per year, and follow the Mediterranean pattern, with a maximum in autumn and winter, while from June to August it hardly ever rains. The rains are abundant especially from October to February.

Winter, from December to mid-March, is mild enough, although it is not as mild as the most southern islands of Greece; in addition, it is rainy, especially in December, when 180 mm (7 in) of rain fall; during some years the rains are particularly abundant. Sometimes there may be outbreaks of cold air from the Balkan Peninsula, with some cold and windy days, and possible slight frosts at night.

Spring, from mid-March to May, is mild; the rains are quite frequent at the beginning, but then gradually become rarer, and sunny days become increasingly more frequent. May is a pleasant month, before the summer heat.

Summer, from June to August, is hot and sunny: the maximum temperature exceeds 30 °C (86 °F) with some frequency, and can reach 35/36 °C (95/97 °F), especially in July and August. Luckily, sea breezes blow, providing relief, at least when the heat is not excessive, and in any case, you can cool yourself down in the sea. This part of Greece, overlooking the Ionian Sea, is outside the area where the annoying but cooling Meltemi blows, so the sea is also warmer (see below).

Autumn, from September to November, is mild (initially quite hot) and rainy, with possible thunderstorms. In September, there can still be a lot of sunny days.

Best Time

The best time to go to Paxos for a beach holiday goes from June to August, although even in the first half of September the weather is often still good.
If you want to go on excursions around the island, you can go from mid-April to mid-June in order to avoid the heat that can occur in high summer.
