The Lowdown
Alright, Rusty here, and I’ve got the lowdown for your local patch. Let’s be straight: looking at the next 16 days, it’s a tough stretch. We’re starting off with a real dry spell, so don’t bother waxing up just yet.
From Monday the 27th of July right through to the afternoon of Monday the 3rd of August, it’s pretty much a write-off. The swell is tiny—mostly under three feet—and the wind is all over the place, swinging from cross-onshore to onshore, often with stormy or rainy vibes. The combined energy is weak, barely hitting 100 (47 at best early on), so it’s just messy, choppy, and flat. This is a big gap for surf, and you’d be better off checking the forecasts for a change.
The first hint of anything rideable shows up on the afternoon of Saturday the 1st of August at Big Wave Bay. We’re looking at a 6ft swell from the SSE, but it’s coming with a fresh 35 km/h onshore wind. The combined energy hits 195 (moderate), but with that wind direction, it’s going to be lumpy and a bit of a chore. Still, it’s the biggest bump on the table.
Then things get interesting. On Sunday the 2nd of August morning, the wind drops to nothing—glassy—with a 3ft ESE swell. The combined energy is low (51), but glassy conditions are a rare gift. You’re looking at small, clean waves, likely crumbly on the inside. It’s a beginner-friendly size, so if you’re learning or just want a few silky rides, that Sunday morning window is the standout of the whole outlook. The water temp is 85°F, which is about average for the time of year, so it’s warm enough for a shorty.
After that, it goes quiet again. The rest of the 16 days are mostly under a foot, with long-period ghost swells that don’t have any push, and the wind chops things up again. No real options worth paddling out for.
So, for the whole period, the only day I’d point a finger at is Sunday, the 2nd of August, early morning at Big Wave Bay. Bring a log and enjoy the clean, small stuff while it lasts.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Big Wave 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.
