Atins

Atins is a delta-lagoon system located in northeastern Brazil where the Parnaíba River meets the Atlantic Ocean. The spot features extensive shallow lagoons separated from open ocean by barrier islands and sandbars, creating a protected but complex riding environment. The tidal delta creates distinctive curved sand formations visible in satellite imagery, with significant water movement patterns that vary throughout tidal cycles. Wind reliability is relatively low at 23.9%, with average winds of 9.3 knots requiring careful timing for sessions. The spot suits intermediate riders comfortable with variable shallow-water conditions and tidal influences. Best conditions occur with easterly to southeasterly winds providing side-shore alignment to the north-facing lagoon. Water is rough-chop typical of delta environments. Riders should account for tidal stage before launching, as sandbar depths change significantly. The system requires local knowledge for safe passage through channels and understanding of current patterns. Small wave average (0.90m) indicates this is primarily a wind-driven rather than swell-dependent spot.
