Conditions at Mossel Bay in April
April: The Autumn Transition Begins
April is the bridge between summer reliability and winter power. Average swell rises to 6.9ft (2.1m) and the period jumps to 11.6s, giving the waves a heavier, more organized feel. The direction mix is still SSW-led at 29 percent, but SW increases to 12 percent and S remains strong at 17 percent. This is the beginning of the season when bigger winter groundswell becomes a regular feature.
Wind quality takes a step back, with ideal offshore flow at 39 percent. Westerly and northwesterly winds become more common as cold fronts approach, so you have to work around the wind shifts. Air temperature averages 18°C, water temp is 18.2°C and precipitation is 1.28mm/day. Surf the dawn patrol before the sea breeze and cold front wind fills in.
