April: The Favourable Window Grows as the Energy Drops
April is a pivot month. The average swell height drops to 2.3ft (0.7m), but the direction spread becomes more favourable than any month since deep winter. S and SSE are dominant at 16.0% and 14.8%, SSW adds 8.3% and SE adds 3.1%, pushing the favourable share above 42%. The problem is size. Most of that southerly swell is small, with a large majority sitting below 1.5ft (0.5m), and only the SSE direction shows a respectable 1-1.5m (3-5ft) class at 2.9%. The wind roses are not kind either: SE and SSE winds each account for 10.2%, which means the same directions bringing the swell are also often trashing the surface. Ideal offshore winds occur only 11% of the time. Average air temperature warms to 14.1C, water temperature climbs to 15.4C, and precipitation is 2.00 mm/day. April still has occasional clean winter-holdover days, but the movement is toward a flatter, wind-dominated spring pattern.
