Guana Bay

Guana Bay is an exposed Atlantic beach break on the windward side of St. Maarten’s Dutch coast. It’s characterized by powerful, fast, mixed-shape surf that often feels “always on” when conditions line up, but the same exposure that creates the fun also makes the launch area and nearshore zone demanding. Wind is dominated by consistent trade winds (Alizés) blowing from the east-northeast/east. These winds are often onshore for the break, which can add choppiness and messiness even when swell is favorable. One key performance factor is swell direction—East or North-East swell is highlighted as the best setup. Safety is a major consideration at this specific beach stretch. Sources warn about heavy/powerful shorebreak, strong rip currents (especially with larger swells), and rocks at the edges of the bay. In addition, the area frequently collects sargassum seaweed, which can make swimming and surfing unpleasant or more difficult—so checking current seaweed levels before going out is strongly advised. The spot is described as rarely crowded and generally oriented toward experienced surfers due to the combination of exposure, heavy shorebreak, and rip-current risk. With the swell up, conditions can become very heavy and prone to closing out across the bay, so planning for a difficult paddle-out and respecting the limits of the group are essential.
