The Lowdown
Alright, Rusty here. Let’s look at what’s cookin’ for Big Wave Bay.
Honestly, it’s a pretty grim stretch ahead. The first week and a half is pretty much a write-off. We’re lookin’ at a solid 9 days of poor surf conditions, with hardly any energy to talk about. The wind is mostly cross or onshore, often fresh, and there’s a lot of stormy weather hanging around. It’s one of those quiet spells where you’re better off checking the cams from home.
There’s a tiny flicker of hope on Saturday, August 1st. The morning shows a 5ft swell from the SSE, with a combined energy of 137 (moderate), paired with a light cross-offshore breeze. That’s the only session in the entire 16 days that even gets a score of 1 out of 10. The surf is described as “surfable waves but very ordinary conditions.” It’s not a standout by any stretch, but it’s the only option on the table. The swell is small enough for beginners, but don’t expect any power. The water temp is about average for this time of year, sitting at 84°.
After that, it drops right back to nothing. The rest of the 16-day window shows tiny, weak swells, often with no rideable height, and the combined energy barely registers. Even the moderate offshore winds that show up in the second week can’t make silky smooth waves out of nothing.
Bottom line: Don’t bother paddling out for at least the next week and a half. The only real window is that Saturday morning, August 1st, and even then, keep your expectations low. It’s a sheltered spot, so it takes a lot to get it going, and this stretch just doesn’t have it.
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.
