Wedge - surf spot statistics

Best Surf Season (May - August)

The core of the Southern Hemisphere winter delivers the most consistent window for quality surf at The Wedge. During these months, the South Atlantic storm track is fully active, generating long-period groundswells (10-11s on average) that wrap into the East-Northeast-facing beach. Critically, the percentage of offshore wind from the SW-WNW quadrant peaks at over 50% from May through July, often producing clean, groomed faces. While much of the swell arrives from the S and SSE directions, the combination of a powerful, organized swell and light offshore flow creates punchy, rippable waves in the 1-2.5m range. The best days occur when a strong frontal system pushes east of the continent and sets up a classic post-frontal SW wind regime – that is when The Wedge truly fires.

Fair Surf Season (April & September - October)

The shoulder months of April, September, and October see a gradual transition in the synoptic weather patterns. Swell heights remain solid (averaging 1.7-1.8m), and you can still find good quality waves. However, the frequency of clean offshore winds drops to the 27-38% range, and the wind direction becomes more variable. The swell period is still decent (9-10s) but less consistent than mid-winter. These months are a gamble: you may score a few days with light SW winds and a well-aligned ESE swell, but you will also contend with more onshore wind events, especially from NE and ENE. Patience is key, and morning sessions are often best.

Low Surf Season (November - March)

During the late spring and summer months, The Wedge is largely dominated by a persistent high-pressure system over the interior, which drives strong, consistent onshore winds from the NE and ENE quadrants. These are exactly the wind directions that ruin the wave quality, turning any swell into choppy, messy conditions. While the swell still arrives – mainly from the E and ESE (optimal directions) – the constant onshore breeze makes it difficult to find a clean, workable wave. Average wave periods drop to 8.7-9.4s, further reducing the power. Only on rare days when a weak trough allows a brief SW wind shift will you score fun-sized, surfable waves. This is the quietest period for dedicated wave-seekers.

February: Waiting for the Shift

February mirrors January: a summer pattern with strong NE (19.8%) and ENE (14.8%) onshore winds. The offshore wind percentage remains low at 26%. Swell height averages 1.6m, and the period inches up slightly to 9.4s. Swell arrives primarily from the ESE (24.2%) and E (23.7%), but again, the onshore flow degrades the surface quality. The Wedge needs a southward dip of the high or a passing cold front to bring SW winds – which happens rarely. Those few days can yield fun, chest-high waves with clean faces, but overall, February is a month of waiting and watching the charts for a pattern change.
