Margaret River - surf spot statistics

Margaret River is a world-class surf destination with consistent year-round swell, primarily driven by ground swells, which dominate 92-97% of the time. The best months for surfers are typically April through September, when the mean swell size increases to 2.7m-3.7m, offering powerful, clean waves. May to August stands out with the largest swells (3.1m-3.7m), ideal for experienced surfers seeking big, hollow waves. However, wind conditions are a challenge, as bad winds (onshore or cross-shore) prevail 76-85% of the time, peaking in the winter months. The most favorable wind conditions, though still limited, occur in April and May (24% good winds), making these months particularly appealing when clean offshore winds occasionally coincide with solid ground swells. The summer months (December-February) see smaller swells (2.3m-2.4m) and near-constant bad winds (85-88%), reducing surf quality. Overall, advanced surfers should target autumn and winter (April-September) for the biggest and most consistent waves, accepting the likelihood of windy conditions, while those seeking slightly smaller but still reliable waves might prefer early autumn (April-May) when wind conditions are marginally better.

October at Margaret River offers solid surf conditions with a dominant swell from the SW direction, producing consistent waves averaging 3.0m in height and an impressive 13.4s period—ideal for powerful, well-formed waves suited for experienced surfers. The majority of swell energy comes from SW to WSW (over 30% of waves are 2m+), ensuring quality groundswells with strong energy and clean faces. However, wind conditions are less reliable, with only 15% of days providing ideal offshore (E-ENE) winds. SE to S winds (onshore) are more frequent, potentially creating choppy conditions, especially when combined with larger swells. Stronger winds (20-40kph) from the S-SSW sector are common, which may disrupt wave quality. For those seeking heavier barrels and challenging surf, October delivers, but patience is required for optimal wind alignment.
