Ionian Weather Information

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.

Whilst you are out on charter there are various ways of getting weather forecasts. Please note that it is sometimes difficult to get accurate forecasts for the Ionian, due to the high mountains and numerous islands in close proximity to each other, resulting in localised weather conditions.

To get an up to date forecast:

Telephone our base for a weather forecast;
Check with the port police;
VHF CH 02 (GMT 06.00 / 10.00 / 16.00 / 22.00);
VHF CH 85 (GMT 06.00 / 10.00 / 16.00 / 22.00);
Navtex – channel 518;

Or if desperate -
listen in on a flotilla briefing (you can also hear where they will be heading so you can avoid!) – although it is not always a good idea to base your decisions on a third hand weather forecast!
