In summer everyone kites in board shorts because the air temperature is around 30+°C and the water temperature can be pretty warm too. You could use a shorty if you want to keep warm kiting alone in the evening into the sunset. In spring and autumn most people use a 3/2 full wetsuit but also thicker as the temperature can range from 25-5°C, the water will be about 10°C. In winter with strong wind it's cold although the temperature rarely drops much below zero, most people use drysuits in winter.

Recommended wind for kitesurfing is wind coming from NE and SE .

There is Thermal wind at Cesenatico, Italy.

In summer Cesenatico gets 8-14 knot SE (Scirocco) thermals on an almost daily basis, if there's any SE winds in the Adriatic this can buck the thermal up to 20ish knots. 8-12 knots is normally flat water or chop, 12+ will form decent waves if it blows long enough. Other onshore, sideonshore winds are the Grecale (NE), the Bora (NE) and the Tramontana (N, NE). All these winds can vary from 8-35 knots or more. The most constant wind is the Scirocco, the gustiest onshore wind is the Bora which can easily range from 20-40 knots in a matter of seconds. In winter you can get pretty flat months but also moments when you will have decent wind at least 2-3 days per week. Or a whole week of Bora which is strong, gusty and onshore so you really need a small kite, a big empty beach and to know exactly what you're doing. The Libeccio is 0-40 knots offshore here but we go to Lido di Volano 40 km north where it's sideoffshore and strong but a bit less gusty or else you can try the lake behind Mirabilandia 20 km north of Cesenatico. You can kite around 100 days/year if you have a good quiver with a big kite, you will get around 30 days windsurfing/year.

Wind usually blows from NE and SE on the spot.
