Still Bay - surf spot statistics

Best Surf Season (May - August)

The Southern Hemisphere winter unleashes its full fury upon Still Bay during these months, with the roaring forties pumping relentless SW and SSW swell directly into the SSE-facing beach. Average wave heights climb to a solid 2.0-2.2m, period lengthens to 12-12.4s, and the wind clock flips in our favor: high pressure cells over the interior trigger frequent light to moderate offshore breezes from NW and NNE, delivering ideal conditions over 47-58% of the time. This is the prime window for pumping, firing surf with long, clean walls that peel down the sandbanks.

Fair Surf Season (April & September)

Transition months offer a mixed bag. April and September still see strong SSW and SW swell averaging 2.0-2.2m and periods around 11.5-11.7s, but the offshore wind window narrows to roughly 35% ideal time. The wind patterns are more fickle: cold fronts brushing the coast bring intermittent onshore pulses, yet when the interior high settles in, the setup can produce rippable to solid waves with occasional long-period gems.

Low Surf Season (October - March)

Summer and early autumn are tough for consistent quality. Average swell height drops to 1.9-2.1m and period shortens to 10.6-11.2s, with the dominant swell from SSW still present but often accompanied by strong onshore winds from the ESE to S quadrant. The percentage of ideal offshore wind plummets to 13-22%, and the majority of days are marred by choppy, crumbly conditions. A few cold-front passages or cut-off lows can deliver brief windows of fun-sized waves, but overall expect a lot of groveling and wind-affected surf.

April: Sweet Spot of Swell & Wind – The Fair Season Peaks

April sees a significant shift. Average swell height stays at 2.0m, but period jumps to 11.7s. The wind quality improves dramatically to 35% ideal. Northerly and northwesterly winds (N, NNE, NW, NNW) now account for over 15% of the time. Swell from SSW (29.5%) and SW (13.8%) is powerful and long, and when combined with offshore flow, Still Bay delivers pumping 1.5-2.5m sets with long period punch. This is a transition month worth watching.
