Jauca is a sheltered lagoon spot on Puerto Rico's north coast, characterized by a protected body of water separated from open ocean by coastal geography. The lagoon faces northeast with a river mouth visible at the southern end, creating a semi-enclosed riding area. The shallow, light-swell conditions (0.77m average) make this suitable for beginners and progression riders seeking flat-water or mellow wave practice. Side-shore northwest winds (315°) would be ideal for safe kitesurfing, though the extremely low wind reliability (0.9%) means consistent sessions are rare. The spot offers protection from larger Atlantic swells due to its lagoon configuration, making it manageable for skill development. However, limited fetch, shallow depths, and surrounding mangrove obstacles require careful navigation. The proximity to residential areas and boat activity suggests caution during peak times. Best suited for beginners in light-wind conditions; intermediate riders may find it too mellow. Water temperature averages 27.2°C year-round, providing comfortable conditions.
