Meltemi wind NW, thermal, starts around noon and stops exactly with sunset. Every day mostly 4.5-6 Bft. 10/12 sqm kite is the most useful. Best time to go is June to August, which is high season, with 80-90% wind. Off-season no regular winds. If in Tigaki is no wind Psalidi has almost a bit because of a wind current.
By plane to Kos and then by bus/taxi. Or with the ferry directly to Kos Town. To the spot with a bus to the Psalidi/waterpark. In front of this is the spot. Or you rent a car. Or take a scooter.
