Ionian Sailing Conditions

The Ionian islands of Greece are renowned for perfect sailing conditions. The Ionian is ideal for sailors of all abilities, and although it is one of the safest and most calm sailing holiday destinations there is still plenty of wind to have some really fun sailing adventures.

On a usual day the prevailing north westerly winds build around midday onwards to Beaufort force 3 - 6 and drop again at sunset - ideal for a great afternoon's sailing. This means you can spend the morning gently meandering around the emerald waters to a lunch time stop in a bay and go for a swim or snorkel, have lunch and then enjoy a great sail to your evening destination!

The winds are fairly consistent and usually result in a very calm evening, at night the winds usually die right down leaving the water looking like a mill pond. This means that you can anchor off in confidence if you choose or have a comfortable night by the quayside.
