The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next 16 days are looking like a total flat spell for the coast. There’s nothing on the table that’s worth paddling out for, so don’t go getting your hopes up. The forecast is screaming “poor surf conditions” for every single session, and I’m not about to sugarcoat it.
Right now, the combined energy of all swells directed here is tiny, barely registering (23), and it doesn’t get any better. Through the end of August and into the first week of September, we’re stuck with swell heights barely cracking 0.7 ft to 2 ft from the ESE or E, with short periods around 4 to 12 seconds. The wind is mostly cross-onshore or cross-shore, chopping everything up. Even when it goes clean or glassy, there’s just no wave to work with.
We’ve got a solid run of days with nothing—from the 26th of August all the way through to the 10th of September—every single entry is a zero on the recommendation scale. The only real change is the wind direction, but it doesn’t matter when the swell is that weak. You’ll see a few moments of light offshore or glassy conditions, like on the 4th of September afternoon or the 7th of September afternoon, but with only 0.3 ft to 0.7 ft of swell, it’s a lake, not a surf break.
The water temperature is about average for the time of year, so no complaints there, but it doesn’t help when there’s nothing to ride. For a beginner-friendly spot like Big Wave Bay, sheltered from the main swell, this kind of blank run is more normal for the area. It’s not a surprise, just a tough stretch.
Hang tight, keep an eye on the charts, and don’t bother waxing up yet. This is a solid two-week gap with no surf on offer.
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.
