April: East Swell on the Rise, South Winds Push In
April sees a clear shift toward the optimal swell window: E, ESE, SE and SSE directions combine for around 46% of all wave energy, led by S at 16.9% and E at 13.2%. Average size dips to 3-4ft (1.2m), but 7.3-second periods keep the waves rideable. The problem is wind direction: SSW is now the top wind at 13.3%, and southerly flow becomes common. Offshore W-NNW winds still occur about 29% of the time, but ideal wind drops to just 24%. Air temps reach 10.1°C and water warms to 9.3°C, setting up the summer pattern.
