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.

October at Dee Why Point offers decent surfing conditions with a mix of swells and variable winds. The average swell height is 1.5m with a solid 8.7s period, providing enough energy for quality rides. The most consistent swells come from the ENE, E, SE, SSE, and S directions, with the majority of waves falling in the 1-2m range—ideal for intermediate to advanced surfers. Swells from the SSE and S tend to bring larger waves (1.5m+) more frequently, with occasional 2.5m+ sets, adding power and shape to the break. Wind conditions are moderate, with only 25% of the time being truly favorable (light offshore or cross-offshore). The dominant winds are NNE to SE, often in the 10-20kph range, which can create chop if blowing onshore. Early mornings may offer cleaner conditions before sea breezes pick up. While not a powerhouse month, October provides a good balance of surfable days with occasional high-quality sessions, particularly when SSE/S swells coincide with lighter winds.
