Seal Point - surf spot statistics

Best Surf Season (May - July)

The heart of winter sees the Southern Ocean roar to life, sending consistent, long-period groundswells marching toward the Cape. Average wave heights peak at a solid 3.1m with periods averaging 12.4–12.5s, offering a steady diet of powerful, well-structured lines. Offshore wind potential also hits its annual high at 36–37 percent, driven by frequent cold fronts that deliver clean W to NW winds in their wake. This is when Seal Point truly fires, with overlapping SW and SSW swells wrapping perfectly into the bay.

Fair Surf Season (April, August - September)

Shoulder months bring a slight drop in consistency but still offer excellent potential. April averages 2.7m at 11.8s, while August and September hold onto 3.0–3.1m with periods around 12s. Ideal wind percentages cool to 28–31 percent, meaning more onshore days from the E and ENE. However, when a strong high-pressure system sits just south and a cold front passes, the windows of W/NW wind align with the remaining SW groundswell, producing firing sessions.

Low Surf Season (October - March)

Spring and summer bring a noticeable lull in size and consistency. Average wave heights dip to 2.4–2.6m and periods drop to 10.9–11.1s. The wind pattern becomes dominated by persistent E and ENE breezes, blowing directly onshore and ruining wave quality. Ideal offshore wind frequency falls to 21–25 percent. While occasional long-period pulses from distant storms in the Southern Ocean can still deliver pumping days, they are often accompanied by poor wind. Patience and careful timing are essential during these months.

February: Size Holds, Wind Remains Tricky

February mirrors January closely with an average swell height of 2.5m and a period of 11.1s. The swell distribution shifts slightly: SSW swells increase to 19.8% and SW drops to 11.9%, while S and SSE contributions hold steady. The wave energy remains solid but requires the right wind to unlock its potential. The wind rose shows a persistent onshore flow from ENE (13.2%) and E (19.9%) at moderate speeds. Ideal offshore winds from the western quadrant (WSW, W, WNW) total 32.3% of the time, but only about 22% is truly clean offshore (W and WNW). Nonetheless, when a strong high settles in the interior and a cut-off low tracks south, you can score periods of NW wind and long, peeling swell lines that make Seal Point a true gem.
