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.

April at Dee Why Point offers decent surf conditions with a manageable mix of swell and wind patterns. The average swell height is 1.6m with a solid period of 9.5s, providing consistent and well-formed waves. Swell direction is predominantly from the east to southeast, with ESE, E, and SSE swells contributing the most to rideable waves—particularly in the 1-2.5m range, which is ideal for intermediate to advanced surfers. The wind is favorable for surfing 33% of the time, with lighter winds (10-20kph) from the north to northeast being most common, though stronger southerly winds can occasionally create choppier conditions. Overall, April sees a good number of clean, mid-sized waves, but wind conditions can be variable, so dawn patrol or late sessions may be optimal when winds are lighter. It's not the biggest or most consistent month, but there are plenty of surfable days for those patient enough to time the conditions right.
