Conditions at Seal Point in April
April: The Window Opens
April is when Seal Point starts to feel like a proper winter set-up. Average swell height jumps to 9ft (2.7m) and period stretches to 11.8s, with a lot more S (8.7%), SSW (16.7%) and SW (13.1%) groundswell pouring out of the Southern Ocean. The E-ESE-SE-SSE window still chips in around 14 percent, and when those directions fire, the point can handle serious size.
Wind quality improves noticeably. The offshore W/WNW/NW/NNW quadrant reaches around 31 percent, while onshore E/ESE flow drops to 21 percent. Ideal surf wind hits 28 percent. Water temperature cools to 17.9°C and air temps average 18.8°C, so a 4/3 wetsuit is the right call. This is a great month for combining solid SSW/SW groundswell with lighter winds and fewer crowds.
