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.

March at Dee Why Point offers decent surf conditions with an average swell height of 1.6m and a solid period of 9.2s, which typically produces clean, well-formed waves. The dominant swells come from the E to SSE directions, with the best consistency and size (1-2.5m) occurring from ENE through SE, peaking in the 1-1.5m range. Larger waves (2m+) are less frequent but possible, particularly from the SSE. Offshore or light cross-shore winds (ideal for surfing) occur 22% of the time, mostly from W/NW directions, though NE and E winds can occasionally create choppier conditions. Wind speeds are generally manageable, with the strongest gusts typically from the S/SSE. Overall, March provides a mix of rideable days, with the best sessions likely when ENE-E swells align with light offshore winds—expect some mid-sized, quality waves but be prepared for variable conditions.
