Our sailing season commences at the beginning of May and ends at the end of October. During this period the weather is suitable and safe for sailing. At any time in this period you can comfortably swim in the sea, get good wind, catch a sun tan and enjoy calm nights. Below is a brief description of the weather throughout this period, and what this means in terms of comfort and popularity:

May / June

Slightly cooler air and water temperatures in May, warming up through June, although you will still be able to swim comfortably and get a sun tan! Not being in the school holidays, the area is generally quieter and it is easier to get a place on the quays. There is a slightly higher chance of rain in early May but it does not usually hang around long. Winds are generally stronger in the tail ends of the season.

July / August

Both air and water temperatures will be at their highest. Our boats are equipped with biminis and wind scoops which are essential at this time of year. Bring a hat and plenty of sun cream! Winds pick up at around lunchtime to F4/F5 and die away as evening approaches. Generally night times will be very calm, resulting in quiet nights and a good night sleep. There is very little chance of rain, however there are chances of the occasional thunder storm, but they do not last long.

September / October

The air temperature reduces as October approaches, however the water is still very warm. In October you will need a sweater and trousers in the evenings, but all boats are supplied with warm duvets and blankets to ensure that you keep warm at night. Winds are generally stronger than in the high season and there is a higher risk of light rain and thunderstorms. The number of flotillas reduces when the school holidays end resulting in a quieter sailing area. In many people’s opinion, May and October are the best times for sailing in the Ionian.

The Coptic Chart was developed in Egypt in ancient times, and predicts significant weather patterns throughout

the year.  It has been proven to be fairly accurate to within 48 hours.  Winds generally set in from the south

west veering west, north west and last around 3 days.  Nisos holds no responsibility for any inaccuracies!
