Kite spot-guide Kos and windy information for kitesurfers
The wind on and around Kos is dominated by two different wind systems: The north wind known as Meltemi, which depends on the general weather situation and the daily produced thermal winds, caused by the nearby Turkish mainland.
The Meltemi is a strong and constant north wind, which makes for perfect side-shore conditions on our main spot Mastichari the whole day during the summer months. As soon as the wind forecast projects northern directions you can normally add a couple of knots. In Mastichari the wind hits the spot without being hindered, however (luckily) quite constant and generally not with more than 6Bft. Thus, here the beginners and intermediates are spared for the rough conditions that typically prevail at many other Greek spots.
Next to the Meltemi, Kos is affected by the daily thermal west wind. The thermal wind is generated throughout the day and caused by the rapid heating of air masses over the nearby dry landmasses of Turkey.
Depending on the strength of the Meltemi, it normally gets distracted in the afternoon and turns from north to northwest or west. So, on days without Meltemi you still have a good chance at westerly thermal winds in the afternoon, which produces perfect, constant winds from 15 to 20 knots for beginners and intermediates.
For advanced kitesurfers, it clearly is important to know where to go on which day, as the wind can be very different from spot to spot.
Another factor influencing the wind are the two islands located just some kilometers north of Kos. Between the islands the wind is being funneled, which causes a jet effect having different strengths of wind on certain spots of the island.
During the change from north to north west wind a short wind break might occur, also in Mastichari. Consequently, you often have two sessions a day, one in the morning with side-shore conditions and one in the afternoon once the thermal winds have kicked in.
