Injidup Carpark - surf spot statistics

Injidup Carpark in Western Australia is a consistent year-round surf spot with a strong dominance of ground swell, making it highly reliable for wave riders. The best months for surfing here are typically from April to September, when swell size peaks and conditions are most favorable. During this period, the mean swell size ranges from 2.7m to 3.7m, with the largest waves occurring in July (3.7m). However, wind conditions are less favorable in these months, with only 16-28% of days having good winds, meaning offshore or light winds are relatively rare. The trade-off is bigger, cleaner ground swells with more challenging wind conditions. The summer months (December to March) offer smaller swells (2.2m-2.4m) and slightly improved wind conditions (17-23% good wind days), but the swell quality remains high due to the overwhelming presence of ground swell (92-97%). Overall, intermediate to advanced surfers will find the winter period ideal for powerful waves, while summer provides more manageable conditions with occasional clean offshore days. For the best balance of swell size and wind conditions, April and May stand out, offering solid swell (2.7m-3.0m) with marginally better wind odds (24-28% good wind days).

September at Injidup Carpark delivers consistent and sizable surf, with an average swell height of 3.5m and a solid 13.9s period, indicating powerful, well-spaced waves. The swell direction is predominantly SW-WSW (peaking around SW), contributing to the majority of waves in the 1.5-2.5m+ range, ideal for experienced surfers. Smaller days (1-1.5m) are rare, ensuring consistent energy. However, wind conditions are less favorable—only 18% of the time offers ideal offshore or light cross-shore winds. Winds are often from the S-SSW, SW, or WSW, increasing in strength (20-50kph), which can create choppy or onshore conditions. The best sessions occur when winds stay below 20kph, typically early mornings or during brief lulls. Overall, September brings high-quality, powerful surf but demands patience with wind conditions. Advanced surfers will find plenty of opportunities, though it’s not a beginner-friendly month.
