The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking.
Honestly, mate, the next couple of weeks are looking pretty grim for a proper paddle. The surf is just not showing up, and when it does, the wind is a mess. We’ve got a long stretch of poor conditions ahead, so don’t get your hopes up.
The only spot on the radar is Big Wave Bay, but it’s a real struggle. The water temp is sitting at 84.4°, which is about average for the time of year, so at least you won’t need a spring suit.
Starting off on Wednesday the 29th of July, we’ve got a weak 3.6 ft swell from the east at a short, weak period of 5 seconds. The combined energy is a measly 70, and it’s just not worth the paddle. The wind is howling out of the east at 19 mph, making it a lumpy, cross-onshore mess. Thursday and Friday are more of the same – tiny, weak swell with rubbish wind. By Saturday the 1st of August, the swell picks up a touch to 4.9 ft from the east, but the energy jumps to 124 (moderate), however, the wind is still a solid 16 mph cross-onshore, so it’s going to be choppy and bumpy. That’s a pass for me.
We get a tiny glimmer of hope on Sunday the 2nd of August afternoon, with a 2.3 ft swell coming in from the east with a light onshore breeze from the SE at 9 mph. The conditions are described as “unknown” which is a bit of a worry, but it’s the best we get. Still, it’s a tiny wave.
From Monday the 3rd of August onwards, the swell drops right off. We’re talking 0.3 ft to 1.3 ft for the next week and a half, with a bit of a longer period swell (16-18 seconds) from the south-east. That long period groundswell would be nice for a point break, but at Big Wave Bay, which is a sheltered beach, it’s just going to be tiny and weak. The wind does turn clean and cross-offshore from the 6th of August onwards, which is a tease, but there’s no swell to ride.
The energy levels are pathetic, often in single digits. There’s even a few days from the 7th to the 9th of August with zero swell. The 10th of August shows a tiny 1.6 ft bump from the east, but the period is a short 4-5 seconds, so it’s just wind slop. The rest of the forecast is more of the same – tiny, weak, and not worth getting wet for.
So, to be straight with you – there’s truly nothing to recommend here. The whole 16-day window is a write-off. It’s one of those blank runs that happens in this area. All we can do is wait for the forecasts to change.

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.
