Conditions at Shipwreck Bay in April
April: Serious Autumn Swell
April is where the surf stats begin to feel genuinely wintry. Average swell height jumps to 6-7ft (2.0m), and the average period peaks at 12.9s-the longest of the entire year. Ideal offshore wind frequency is still 26 percent, but the wind fields become more variable, with S at 11.5 percent, SSW at 9.7 percent and SW at 7.3 percent. The swell rose shows SW at 45.0 percent, WSW at 10.7 percent and SSW at 11.2 percent, while N-trending swell remains in the low single digits. The north-facing bay needs those rarer north pulses to organize; otherwise the south-west energy can be fat, wedgy or walled. Water temp drops to 19.3°C and precipitation climbs to 2.79mm/day, so autumn is for thick neoprene and picking your windows carefully.
