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.

July: Winter Peak Holds Strong

July maintains the high standard set in June. Average swell height remains at 3.1m with a period of 12.5s, the longest of the year. Swell directions are nearly identical to June, with SW (16.6%) and SSW (9.0%) still leading, and a slight increase in WSW (2.2%). The wind pattern holds steady: onshore flows are minimal (ENE 8.4%, E 3.8%), and westerly winds dominate (W 23.7%, WSW 14.0%). Ideal offshore wind remains at 36%. The consistency is remarkable—expect solid 1.5–2.5m waves with occasional bigger sets. The combination of long-period groundswell and frequent offshore winds makes July a top month for dedicated surfers.
