Conditions at Banana Beach in April
April: Lower Period, More Punch
April is where the North Atlantic energy starts to transition from winter groundswell to spring windswell. Average size is still a healthy 2.0m (6-7ft), but the average period slips to 10.9s - rideable, punchier, but without the long, smooth runners of deep winter. Swell direction is almost absurdly NNW-dominated at 46.3%, with NW (23.9%) and WNW (6.7%) secondary. For a west-southwest facing beach, that means more refraction and shorter walls than a pure SW/W angle would deliver.
Wind quality becomes the main issue: ideal conditions fall to 39%. The offshore quadrant from NNE through E shrinks to around 16%, while cross-shore NNW/NW flow dominates the wind rose. The onshore SW-W sector sends more texture into the lineup as well. Air temps climb to 19.1°C, water sits at 17.1°C, and rain drops to 0.61mm/day. It is still very surfable, but the margin for error is tighter.
