The Lowdown
Alright, I’m Rusty, and I’ve been staring at the charts for White Rocks. Let’s just get it out there up front: this is a rough stretch. The whole 16-day window is a real battle, and for most of it, you’re better off doing something else. There’s really just one standout, and it’s way out there, so we’ll get to it.
Right now, the water is sitting at 60°, which is about what you’d expect for this time of year, nothing wild there.
The first week is a write-off. From Wednesday the 26th of August through to Thursday the 3rd of September, it’s just poor surf, day after day, with a few tiny, weak swells. The best you’ll see in that first block is maybe a 2 ft peak on the Saturday morning, but it’s cross-shore wind and a pathetic 4-second period. The energy is barely there (20). The waves aren’t forming, the wind is messy, and there’s no reason to paddle out.
Then we hit Friday the 4th of September. The swell ramps up in size, but so does the wind. We’re looking at a near gale from the west, blasting across the break. The combined energy jumps to 306, but it’s a lumpy, blown-out mess. Not for surfing. This setup looks more interesting for kite surfing than paddle surfing.
Now, here’s the one that got my attention. The standout is Saturday the 5th of September. We’ve got a solid 10 ft to 12 ft swell from the northwest, with a long period of 13 seconds – that’s proper groundswell energy. The combined energy is massive, 2815, it’s a heavy ocean. The wind is a moderate cross-shore, which is okay, but here’s the catch. The notes say it’s predicted to be too big for this break. At 10 ft+, this is experts-only territory. It’s a big, powerful swell, and for a beach setup, that long period (over 15 seconds) can make it break straight and fast. It’s a real challenge, even for the experienced crew. If you’re a seasoned charger and you know White Rocks, this might be your window, but it’s not for the faint of heart.
After that, the surf drops back into poor conditions, with a bit of a gap through the rest of the second week. Sunday the 6th is marginal, with a 8 ft swell but iffy winds, and then it’s back to small, weak, and messy until the 10th of September, where we finally see a clean, small 2 ft swell from the west with a decent 11-second period, but it’s only scoring a 1 out of 10. Surfable, but ordinary.
So, bottom line: the whole 16-day stretch is mostly blank. The only real standout is the 5th of September, and it’s a big, expert-only affair. Keep your eyes on the charts, but don’t hold your breath.
Rusty.

Information about the White Rocks Surf forecast
The above surf forecast table for White Rocks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at White Rocks can be found by selecting the local surf guide option on the grey menu. Our White Rocks 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 (White Rocks) 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 White Rocks 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.
