About
Jan Thiel (Seru Grandi) is a sheltered, flat-water bay setup best known for kitesurfing under steady trade winds. The wind is described as consistently easterly and active year-round, with typical ranges often landing around 15–25 knots, and generally steady gust behavior. At the waterline, conditions are reported as calm/flat with little to no shore break, and the bay is described as shallow enough for beginner-friendly sessions in some accounts (knee-deep water / shallow water close to shore). The launch access involves driving toward the ostrich farm, continuing past paved road onto an unpaved section, and then turning through an open gate to reach the water. Mangroves and saltwater-resistant vegetation surround the bay. At the same time, multiple safety signals emphasize that the wind is side-offshore/offshore and that rescue capability is limited for this specific launch. If something goes wrong, riders may drift toward the open ocean, making it important not to ride alone and to plan for safety before launching. Extra caution is warranted around rocky entry/exit areas and any turbulence very close to the cliff line. Overall, the spot is often framed as an accessible learning area due to flat, steady conditions and shallow water, but it can also function as a technical/expert-only spot depending on how offshore the wind is, where you launch from, and whether you can reliably return to shore without assistance. Plan to match the conditions to your skill and self-rescue ability rather than the “flat water” appearance alone.
