Woolamai - surf spot statistics

Best Surf Season (May - September)

Winter and early spring bring the most consistent combination of powerful, long-period swell and favourable offshore winds to Woolamai. As the Roaring Forties intensify, low-pressure systems track across the Southern Ocean, delivering a near-constant stream of SW groundswell. The average wave period sits around 12 seconds, with heights frequently in the 1.5-2.5m range – solid, pumping surf that works beautifully on the south-facing beach. Offshore winds from the N to NW quadrant dominate over 40% of the time, grooming the waves to perfection. This is the prime window for quality sessions on the Points and beach breaks.

Fair Surf Season (March - April & October - November)

The transition months offer a mix of solid swell and increasing wind variability. During March and April, the ocean is still fired up from winter, with average periods around 12s and heights often in the fun to solid 1-1.5m range. However, the ideal wind percentage drops to 25-38%, meaning you'll need to pick your days as onshore SE-SSE winds creep back in. October and November see the tail end of winter's energy, with average swell heights at 1.5-1.6m and periods around 11.5-12.2s. Offshore flows are less frequent (25-32%), but when a high-pressure system parks over the Tasman Sea, it can channel clean N-NW winds over the peninsula, making for excellent mid-morning sessions.

Low Surf Season (December - February)

Summer is the quietest time for reliable surf at Woolamai. The dominant SW swell still rolls in, but it's often smaller and less consistent, averaging 1.5m with a shorter 11s period. The real issue is the wind: SE and SSE onshore flows blow over 30% of the time, chopping up the waves. Light offshore winds from the north occur only 19% of the time. While you can still score fun, rippable waves on good days, the overall conditions are more grovelly and less dependable. Early mornings often offer the slickest windows before the seabreeze kicks in.

August: Late Winter Gold – Powerful Groundswell

August holds onto winter's power. Average swell height remains at 1.7m, and the period peaks at 12.5s – the longest of the year. This means the swells are extremely powerful, with a high percentage of waves in the 1.5-2.5m range. SW (37.0%) and WSW (18.0%) dominate, and there's a notable increase in W and WNW contributions. The ideal wind percentage is still high at 47%. NW and WNW winds blow 32.5% of the time, providing excellent grooming. Onshore SE-SSE winds are minimal (4.4%). August is the last prime month before the wind shifts begin. The combination of very long period groundswell and offshore breezes creates epic conditions – waves that are both heavy and rippable. This is a month for charging. If you can handle the cold, you'll be rewarded with some of the best surf of the year.
