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.

January at Black Rock offers moderate surf conditions with an average swell height of 1.6m and a decent period of 8.4s, providing consistent, rideable waves. The dominant swell directions are ENE, E, and SE, contributing to clean, well-formed waves, particularly in the 1-2m range, which accounts for the majority of swell activity. Wind conditions are less favorable, with only 24% of winds being ideal for surfing, typically light offshore or cross-shore breezes from the ENE or E. However, stronger onshore winds from the N, NNE, and S are common, which can degrade wave quality. Overall, expect a mix of good and messy days, with the best sessions occurring when ENE swells coincide with lighter winds from the east or northeast. Intermediate to advanced surfers will find the most success, as the spot can handle size and power.
