Dee Why Point - surf spot statistics

Dee Why Point, Australia, offers surfable conditions year-round, but the best months for quality waves and favorable winds are typically from May to August. During this period, ground swell percentages increase to around 30%, while wind swell remains dominant but slightly reduced compared to other months. The mean swell size hovers around 1.5–1.6 meters, providing consistent, manageable waves. Wind conditions improve significantly in these months, with good winds occurring 42–43% of the time in May, June, and July—far better than the summer months when onshore winds (bad conditions) dominate at over 80%. Autumn (April–May) and early spring (September) also offer decent windows with a gradual transition in swell composition and wind quality, though not as reliably as mid-winter. The summer months (December–February) suffer from high wind swell dominance (85–87%) and poor wind conditions (bad winds 82–84%), making sessions less consistent despite the similar swell size. For surfers prioritizing cleaner, more powerful waves with offshore or light wind assistance, the winter window from May to July stands out as the prime season at Dee Why Point.

July at Dee Why Point offers decent surf conditions for experienced riders. The average swell height is 1.5m with a solid period of 9.6s, producing well-formed waves. The dominant swell directions are SSE, S, and SE, contributing most frequently to rideable waves in the 1–2.5m range. Wind conditions are favorable 43% of the time, with offshore or light winds primarily from the W, WNW, and NW sectors, keeping surfaces clean. However, strong SW-WSW winds (20-30+ kph) can occur, potentially creating choppier conditions. The best sessions will likely come during SSE swells paired with lighter W/NW winds, offering powerful yet manageable walls. While not massive, the consistency of overhead waves (1.5m+) makes July a reliable month for good surf, though wind shifts require careful timing. Intermediate to advanced surfers will find the most success here.
