Su Tiriarzu (Pasada/Posada)

Su Tiriarzu is a long sandy beach in the Posada area that’s especially valued for crystal-clear water and an organized setup for wind sports. The beach is medium-sized with sand bottom, and the water is described as flat to choppy depending on conditions. Near shore it stays shallow, then deepens quickly, with no standing reef reported—an environment that supports progression and longer freeride sessions. The wind is characterized as a thermal sea-breeze pattern, typically building from mid-morning and peaking in the afternoon. Reference windows consistently place the strongest period in the 13:00–18:00 range, and the most reliable months run from April/May through October (with May to October highlighted for thermal activity). Reported wind strengths commonly sit around roughly 12–25 knots, and the thermal component can add a further 5–10 knots on top of the background flow. For kitesurfing, the spot is centered on an authorized kite zone associated with the local school, and using that lane is emphasized during the main season (with stricter rules referenced for June–September / peak summer hours). Swimmers are a key hazard in summer, so the main safety expectation is to keep launch and kiting activity inside the designated area and coordinate to avoid swim traffic. In terms of comfort and logistics, there are beach-side facilities such as showers and toilets, plus restaurants/bars operational during summer months, and camping directly at the spot. Water temperatures are typically about 14–15°C in winter and rise through spring to around the mid-20s °C in July/August (with sources listing up to ~25°C in summer), so a wetsuit is usually needed outside the warmest period.
