Punta Trettu is a 700-meter sand spit that separates the Sardinian Sea from the Sant’Antioco lagoon, in the municipality of San Giovanni Suergiu. This spot is about 5 minutes from the Kite House Sardinia, in the Matzaccara area, and points directly towards the island of Sant’Antioco.
It is one of the best kitesurfing spots in Sardinia, if not in Europe, thanks to its consistent wind all year round and flat water. Riders come here for the friendly atmosphere and ideal conditions, with schools and services on site.
The spot is well organized, with areas dedicated to lessons and free practice, monitored by beach staff.
The wind data shown here comes from ERA5 (via Open-Meteo) over 4 years, reprocessed to reflect realistic conditions.
👉 Average wind has been calibrated to avoid the usual underestimation of models.
👉 Gusts have been corrected by a median ratio to avoid unrealistic extreme values.
👉 Each day is summarized by the median wind (P50) observed during useful hours (8am–8pm), then classified into wind ranges.
👉 The weighted mode mixes average wind and gusts to best reflect felt wind.
flatflatThe spot at Punta Trettu offers a perfect orientation for all winds, making it a rare place on the southwestern coast of Sardinia. The East wind (Levante) comes directly into the bay and works wonderfully, making the spot rideable even in this direction. The West wind (Ponente) and Southwest wind (Libeccio) are excellent from spring to autumn, especially if the sky is clear, and the Maestrale (Northwest) is ideal for flat sessions.
The water surface is flat as a lake regardless of the tide, with very shallow and sandy bottoms, perfect for freestyle and learning. The launch area is easily accessible from the sandy beach, and the take-off zone is wide and reachable 10 minutes on foot from the parking lot. There are two distinct areas: one for beginner lessons near the shore, and a larger one for independent riders, separated by a sand spit.
Be careful of the deep navigation channel towards Sant’Antioco, where boats pass: kiting is prohibited and priority is given to boats. The water remains clear and flat, with few waves even in strong winds, and you can stand for a long time thanks to the shallow depths.
Ideal conditions are with side-on wind of 15 to 30 knots from NW, E, or SE, for perfectly flat water and ample space.
The water is crystal clear and flat, with a sandy and very shallow bottom. There are few waves thanks to the protection of the bay, ideal for technical freestyle.
Currents are generally weak in the bay, but more pronounced in the deep natural channel that connects to Sant’Antioco. The tide does not significantly influence the spot, which remains suitable in all conditions.
For typical winds of 12-40 knots, plan for sizes of 7 to 11m² depending on your weight and the day. 9-11m for moderate winds, 7-9m when it blows strong.
