April: Long-Period Southern Swell Arrives, Winds Mess It Up
April marks the transition toward spring and summer. The average wave period jumps to 13.4s, signalling more long-period southern-hemisphere energy, while average height holds at 1.0m (3ft). Swell direction is WSW at 40.6%, SW at 27.9%, W at 24.4% and SSW at 6.2%. There is plenty of 3-5ft (0.9-1.5m) material in the mix, especially from the more favorable WSW and SW directions.
The problem is wind. Ideal offshore flow falls to just 13%, with onshore W at 24.2% and WSW at 17.2% dominating the afternoon. Water temperature is still cool at 14.0C, air temperature averages 15.4C, and rainfall drops to 0.58 mm/day. The swell is powerful on paper, but you will need a light land breeze and an early session to beat the daily onshore chop.
