April: Winter Swell and Offshore Windows Line Up
April marks the true beginning of the fair-to-good season. Average height jumps to 5-6ft (1.5-1.8m), period lengthens to 9.1s, and the ideal wind score rises to 44%. The swell window broadens: E (17.1%), ESE (16.5%), SE (16.5%) and SSE (15.9%) feed the beach, while S (12.7%) and SSW (3.3%) add a more southerly component - a sign that South Atlantic cold fronts are starting to generate swell farther afield. The distribution is meaty, with 5-8ft (1.5-2.5m) waves accounting for a solid share of the S and SSE energy. Offshore winds from W (3.3%), WNW (3.2%), NW (4.2%) and NNW (9.2%) become more common, offering glassy morning sessions. Water is still 22.7°C and air a pleasant 19.6°C, with the lowest precipitation of the year at 3.44 mm/day. This is a month of opportunity.
