April: Swell Direction Lines Up, Winds Slack Off
April is a classic 'swell vs. wind' battle at 7-11. The swell window improves dramatically: E, ESE, SE and SSE swells combine for over half the wave distribution, with a strong S component adding southern hemi energy. Average surf height is still around 3.5ft (1.1m) at 7.3s, and the swell is often more organized with higher percentages in the 0.5-1m and 1-1.5m classes.
However, ideal wind percentages drop to 35%, the lowest of the year. The offshore W/NW flow is weaker and less frequent while SSW and SW winds become more dominant, blowing cross-shore and putting a bump on the surface. Water temp is a chilly 8.9°C and air temp averages 10.1°C, so the springtime warmth is starting to arrive even if the ocean lags behind. The best sessions come when a departing coastal storm leaves just enough NW wind in its wake to groom the abundant E/SE swell.
