Conditions at Shipwreck Beach in April
April: Trade Swell Takes Over
April marks the transition to the trade swell season. Average wave height dips to 7ft (2.1m), period falls to 10.3s, and the spectrum becomes dominated by ENE and E swell, with NE and NNE secondary. The clean NNW winter groundswell disappears from the average picture, and south quadrant swell remains negligible. This is when the northeast trade winds become relentless, blowing from ENE 56 percent of the time and dropping ideal offshore wind coverage to just 18 percent. Surf becomes more wind-swell in character, with peaky, crumbly conditions rather than the long, organized winter lines. Water temperature is 24.2°C, air averages 23.2°C and precipitation eases to 1.6 mm/day.
