Black Rock - surf spot statistics

Black Rock, Australia, is primarily a windswell-dominated spot, with ground swells playing a minor role throughout the year. The best months for surfing here are from February to April, when ground swell percentages are slightly higher (19-27%) compared to other months, and wind conditions are relatively better (27% good winds in February and March, 24% in April). The mean swell size during this period hovers around 1.6-1.7m, offering decent surfable waves. Wind conditions deteriorate significantly from May to August, with only 13-18% favorable wind days, making these months less ideal due to frequent onshore and cross-shore winds. The swell size remains consistent year-round (1.5-1.7m), but the low ground swell contribution and poor wind conditions outside the early-year window limit quality surfing opportunities. September to December sees a return of slightly better wind stats (19-25%), but the dominance of windswell (81-87%) and minimal ground swell reduce wave quality. Overall, late summer and early autumn (February-April) provide the most balanced conditions with a modest increase in ground swell and marginally better wind alignment. Surfers should prioritize this window for cleaner, more reliable waves, though even then, windswell remains the primary energy source.

November at Black Rock presents a mix of surfable conditions, though consistency and wind play a significant role. The average swell height is 1.6m with an 8.3s period, indicating generally rideable waves, though they tend to be on the smaller side for advanced surfers. The most dominant swell directions come from the NE, ENE, and S-SSE sectors, with a high frequency of waves in the 1-2m range, offering decent energy but rarely pushing into larger, more powerful sizes. Notably, swells from the S-SSE quadrant (SSE, S, SE) contribute to the majority of waves in the 1.5-2.5m range, making them the most promising for better sessions. Wind conditions are less favorable, with only 23% of days offering ideal offshore or light cross-shore winds—typically from the NW to ENE sectors. However, stronger onshore winds from the S-SSW and NE directions are common, often disrupting wave quality. For surfers, the best windows are likely during early mornings or days with lighter NE/E winds, capitalizing on the cleaner S-SSE swell energy. Patience and timing are key, as the spot relies on swell consistency and wind cooperation to really perform.
