April: Shoulder Season Size and Directional Frustration
April is where the swell curve starts to rise: the average reaches 9ft (2.7m) at 11.8 seconds, but the ideal wind window drops to 27 percent. SW now accounts for 13.1 percent and SSW 16.7 percent, pushing the Southern Ocean influence to the forefront; E swell remains scarce at 1.7 percent. The wind field is more westerly, with W at 21.1 percent and WSW at 14.7 percent, while ENE still grabs 15.8 percent. This is a classic shoulder month: plenty of long-period energy in the water, but the direction mismatch at this NE-facing break is real. Air temperatures ease to 18.8°C, water to 17.9°C, and rain drops to 1.41 mm/day. Look for days with light S/SSW winds and any E swell to make Cape St Francis sparkle.
