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).

December at Injidup Carpark offers solid surf conditions, with an average swell height of 2.3m and a healthy period of 12.6s, indicating powerful, well-spaced waves. The dominant swell direction is from the SW, contributing the majority of rideable waves, especially in the 1.5–2.5m range, which occurs frequently. Larger sets over 2.5m are less common but present, mainly from the SW direction. Wind conditions are a mixed bag—only 18% of the time is the wind ideal for surfing, typically when it's light or offshore. The most consistent winds come from the S to SW sectors, often in the 10–30kph range, which can create side-shore or onshore chop. ESE to SSE winds bring stronger gusts (20–40kph), potentially disrupting conditions. Cleaner sessions are rarer but possible when winds shift W or WSW at lower speeds. Overall, expect powerful, mid-sized SW swells with variable wind interference, requiring patience for optimal windows.
