Tumon Bay (Guam)

Tumon Bay is a small, sand-based, crystal-clear lagoon setting on Guam, characterized by shallow, protected flat-to-choppy water. Because the water is very shallow over reef and coral areas, the main limiting factor for riding is tide depth—sources specifically warn that you need at least a mid-tide to reduce the risk of hitting the reef. Wind is dominated by Northeast trade winds, with the best season for reliable conditions described as December through April (and commonly extending toward May). Wind flow is generally described as steady, and typical riding wind is around 15–25 knots. Launch access is described as straightforward, with commonly used launch sites near major hotels along the bay. Safety considerations are central at Tumon Bay: swimmers are present, and hazards include reefs and corals (including sharp coral and sea urchins). Strong currents can form near reef channels/cuts where water exits the lagoon, so riders are advised to watch those areas closely. A Marine Preserve is noted, with restrictions and designated swimming zones that riders should respect. Amenities are generally focused on the hotel/tourism corridor, including parking and beach facilities (such as restrooms and showers). Overall, the bay is presented as a convenient and popular tourist destination, with water sports areas that can get busy—especially on weekends.
