Arena (Garajau Reserve)

Arena sits on the leeward south coast of Madeira inside the Garajau reserve, with the bulk of the island to the north and west shielding the dominant W-NW-N Atlantic groundswell — the reason this stretch is so consistently calm and divable. The Ponta do Garajau headland to the WSW adds shelter from the SW quadrant. The open window is the southern Atlantic: the S and SSE sectors face straight out to sea and carry any south swell or sustained southerly wind directly onto the reef, with the SE-E arc partly open along the coast, though the Desertas islands trim the ESE. Northerly and westerly weather is effectively blocked, so the site is generally sheltered and only exposed when a Southerly blow or distant south swell builds surface chop over the shallow reef top.
