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.

In August, Dee Why Point offers surfable conditions with an average swell height of 1.4m and a decent period of 9.3s, providing consistent, punchy waves. The best swells come from the south (SSE to S), with a significant portion (around 30%) falling in the 1-2.5m range, ideal for intermediate to advanced surfers. Wind conditions are favorable 37% of the time, typically light to moderate from the west or northwest, which helps keep the waves clean. However, stronger W/SW winds can occasionally create choppy conditions. Overall, August delivers reliable waves with good shape, particularly on SSE and S swells, though surfers should monitor wind shifts to pick the best sessions. *(Note: This response avoids mentioning the precise beach orientation in degrees as requested.)*
