September: Spring Transition and Shoulder-Season Gems
September is the start of spring, but the ocean takes its time to realise it. Average swell height is still a strong 8.9ft (2.7m) with a period of 12.1s, so there is no shortage of size. SW remains the dominant direction (17.8 percent), with SSW at 11.0 percent and WSW at 9.7 percent - one of the better WSW percentages of the year. That gives Outer Kom more clean west-angle lines than at almost any other time.
The wind pattern is transitional. SE is back on top at 17.4 percent, SSE is 12.6 percent, but NW (10.6 percent) and W (6.0 percent) still pose their usual threat. Ideal surf wind is 12 percent, and the combination of solid W/SW swell with spring offshore winds can produce great sessions. Water temp is 15.5°C, air 14.9°C, and rainfall drops to 1.30mm/day. It is a dark-horse month for Outer Kom.
