The Lowdown
Alright, let’s get into it, folks.
Well, to be straight up with you, the outlook over the next 16 days at White Rocks is a tough one. There’s really nothing on the table that’s going to get the heart pumping. We’ve got a long stretch of small, weak, and mostly messy surf, so grab a coffee and wait it out.
Starting right now, through this week and into the first few days of September, it’s mostly tiny waves with poor conditions. We’re talking knee-high slop, speeds all over the place, and onshore or cross-shore winds chopping everything up. The combined energy is weak, mostly sitting under 100 for days on end. You’ll see a few 1ft to 2ft swells coming from the WNW or NW, but with short, weak periods and crummy winds, it's just not worth paddling out.
There’s a glimmer on Friday morning, September 4th. That’s our best shot. We get a bump in swell to about 6ft from the WNW with a longer period of 12 seconds (groundswell), and the combined energy jumps to 972—still moderate, but heading in the right direction. The wind is a light cross-offshore from the SW, keeping it clean. This is a decent window for the more seasoned local crew, but it gets nuked quickly by afternoon when the wind swings and gets choppy. For beginners, the size is pushing the upper limit.
Saturday the 5th morning also offers a similar clean setup with easing 5ft swell from the NW, but by the afternoon it drops off. Still, that Saturday afternoon looks glassy with light NNW winds and a 4ft WNW swell, which could give a couple of fun, clean waves. It’s on the smaller side but you might find a few if you’re patient.
After that, early the next week gets blown out by strong winds, with the swell hanging around 4ft to 6ft but getting absolutely torn up by 25 to 37 mph gusts. That’s borderline kite-surfing territory, not really paddle surfing. Combined energy sits in the 200-500 range (moderate), but it’s ugly.
By September 10th and 11th, we’re back to tiny, weak surf and the window closes.
The water temp is sitting at around 60°F, which is right about average for now.
So, to sum it up: if you have to get wet, try Friday morning September 4th for a clean 6ft NW groundswell, or keep an eye on the glassy Saturday afternoon the 5th for a smaller but tidy 4ft. Nothing else stands out. It’s a long, flat, and blown-out run. Forecasts can change, though, so don’t lose all hope.
Stay tuned.

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.
