Conditions at Port Alfred in April

April: The Window Opens - Better Winds, Stronger Swell

April is where Port Alfred starts to become properly interesting. Average swell height remains at 1.8m (5.9ft), but the period extends to 11.1s and the percentage of surfable 1.5-2.5m (5-8ft) waves increases noticeably. The swell plot is cleaner: SSW dominates at 25.0%, S at 19.2%, SSE at 13.1%, and SE at 11.4%, while E and ESE energy drops. This is a real groundswell mix rather than a summer windswell mix. The wind climatology makes a leap forward too: ENE is down to 16.1%, E to 6.8%, and the offshore N/NNW/NW/WNW component strengthens to the point where ideal conditions occur 39% of the time. WSW and W winds are still common, so it is not all clean, but the balance has shifted. If a low-pressure system tracks south of the country, April can deliver long-period S/SSW swell with light offshore mornings. Water temperature is 18.4°C, air temperature averages 20.0°C, and precipitation is 1.72 mm/day.
