The Lowdown
G’day, Rusty here. I’ve had a good look at what’s cookin’ at Big Wave Bay over the next sixteen days, and to be honest, it’s a bit of a flat spell. The whole stretch from now right through to the end of the period is a quiet one for paddle surfing. You’re looking at a solid run of days with barely a ripple on offer.
For the first week, from Saturday the 29th of August right through to Sunday the 6th of September, the swell is tiny – we’re talking 0.3ft to 2ft at best, with short, weak periods. The combined energy of all swells directed here is next to nothing, mostly single digits and low twenties (2 to 21), so there’s just no grunt in the water. The winds are often light and variable, with a few glassy moments, but with no swell to work with, you’re just staring at a flat ocean.
Moving into Monday the 7th of September, it’s more of the same. The swell barely nudges above 0.3ft, with combined energy still stuck at 2 to 5. There are a few hints of clean conditions, particularly on the Wednesday morning (9th September) with a light offshore from the WNW and a longish 11-second period, but the swell is just too small to ride. You’d be paddling for nothing.
Then, from Thursday the 10th of September, we finally see a little life. The swell bumps up to 2ft to 2ft from the east, with periods around 4 to 8 seconds, and combined energy climbs into the low double digits (12 to 58). This is still weak to moderate energy, and the wind is mostly onshore or cross-onshore, making for choppy, bumpy conditions. By Saturday the 12th, it’s a mess with moderate cross-onshore winds and chop. The only real highlight might be the Thursday morning (10th) when it’s glassy with light offshore winds from the southeast, but the 2ft swell and short 4-second period mean it’s gutless. The water temp is sitting at a warm 84°, about average for this time of year, so that’s a small comfort.
Bottom line: there’s no standout surf here. The whole 16-day window is a write-off for anything rideable. It’s the kind of blank run that happens now and then – the forecasts can change, but as it stands, you’re better off waiting for a better pulse of energy.
Rusty.

Information about the Big Wave Bay Surf forecast
The above surf forecast table for Big Wave Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Wave Bay can be found by selecting the local surf guide option on the grey menu. Our Big Wave Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Big Wave Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
