May: The Winter Engine Fires Up
May is the statistical peak of Kommetjie's prime surf season. Average swell height climbs to 8.5ft (2.6m), average period to 12.4 seconds, and ideal conditions reach 19%, the highest of the year. The frontal belt of the South Atlantic is now active, and the swell distribution shifts west: SW contributes 26%, WSW jumps to 12%, and SSW adds 12%. This is the direction mix that truly lines up with Kommetjie's west-north-west exposure. Wind is a tug-of-war between NW/NNW onshore flow ahead of fronts and SE/SSE offshore flow behind, but the latter still carries the statistics. Water temperature drops to 16.6°C, air averages 16.5°C, and precipitation rises to 1.57 mm/day as fronts move through. Expect sessions in the 6-8ft (1.8-2.4m) range with plus days over 8ft, and some of the longest, cleanest groundswell windows of the year.
