Conditions at Il Bunker in April
April: Smaller Swell and the Onset of Cross/Onshore Winds
April marks the end of reliable winter swell. Average wave height drops to 2.3ft (0.7m) with an average period of 5.0s, and the ideal surf wind window falls to 16%. S/SSW/SW swells remain the primary source at about 38%, but a growing share of the energy comes from the SSE and S quadrant, often associated with advancing low-pressure systems. The catch is that winds from SSE, S, SSW and SW now rival the offshore flow, creating crumbly, onshore-textured surf when the swell arrives. Air temperatures warm to 14.1°C, water temperatures rise to 15.7°C, and precipitation remains around 2.0mm/day. There are still morning windows with N/NNE offshores, but be prepared for smaller, more inconsistent days.
