Scarborough - surf spot statistics

Scarborough in Australia offers consistent ground swell throughout the year, making it a reliable surf destination. The best months for surfing are generally from May to September, when ground swell dominates (89-95%), swell size peaks (1.3-1.6m), and wind conditions improve compared to other months. During this period, offshore winds (good wind conditions) occur around 20-28% of the time, which is significantly higher than the rest of the year. Winter months like June, July, and August stand out with the largest swells (1.5-1.6m) and the lowest probability of no swell (2-4%). However, even in these optimal months, onshore winds (bad wind conditions) remain prevalent (72-75%), so surfers should time sessions carefully. The worst conditions are from November to March, when swell size drops (0.9-1.1m), and bad wind conditions spike to 85-89%, making clean sessions rare. While Scarborough rarely lacks swell (no swell below 13% year-round), the key limiting factor is onshore winds, which are most favorable in late autumn and winter. Overall, advanced surfers will find the biggest and cleanest waves from May to September, particularly in mid-winter, though consistent ground swell ensures rideable waves year-round.

September at Scarborough delivers consistent surf with an average swell height of 1.5m and a robust 14.1s period, ensuring well-formed, powerful waves. The dominant swell direction is WSW to W, with WSW swells (6.79% of 1-1.5m and 8.22% of 1.5-2m) providing the cleanest and most rideable waves, while W swells contribute smaller but more frequent waves (35.55% at 0.5-1m). Larger swells (2m+) occur sporadically, primarily from WSW (6.01% at 2-2.5m). Wind conditions are less favorable, with only 20% of days offering ideal offshore or light cross-shore winds. Winds from the E to SE sectors (10-20kph range) are most common, often creating choppy conditions, while stronger SW to W winds (20-40kph) can further degrade wave quality. Advanced surfers will find the best sessions during WSW swells paired with lighter ENE or E winds, but patience is required as consistency varies. Overall, it’s a month of solid swell energy but variable wind luck.
