The Lowdown
Alright, let’s get into it. The 16-day window is a bit of a grind overall, with a lot of tricky conditions to work through. The only real light at the end of the tunnel comes right at the start of the second week, so we’ll have to be patient.
The first week is pretty much a write-off. From Saturday the 29th of August all the way through to Sunday the 6th of September, we’ve got a run of poor surf conditions. Winds are mostly cross-on or onshore, sometimes fresh to strong, with a lot of short-period, messy swell. The wave energy is mostly moderate (between 136 and 683) but the quality is just not there. It’s a real slog.
Then, after a long gap, things finally look up on Monday the 7th of September. That’s the standout moment. Whitesand Bay gets a clean, glassy morning with zero wind and a 6ft SW groundswell coming from the west, with a 10-second period. The combined energy hits 536, which is strong, and the conditions are described as “glassy” – that’s as good as it gets. The water is a touch warmer than normal for this time of year, sitting at 63°, which is a nice bonus. The surf is best for intermediate to advanced surfers at that size, and the WSW swell direction is a good match for the optimum. The afternoon stays clean with a gentle cross-shore, but the swell drops a little to 5ft.
The rest of the second week fades out quickly. Tuesday the 8th to Wednesday the 9th drops off in size and energy, with light winds but much smaller waves. From Thursday the 10th of September onwards, it’s back to near-gale and strong winds, with tiny, weak swell – not worth a paddle.
So, if you’re keen, pencil in the morning of Monday the 7th of September. That’s your window. The rest is a test of patience.

Further information to help with frequently asked questions about our surf forecast for Whitesand Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
