The Lowdown
Alright folks, Rusty here. Let's get into what's on the table for the next couple of weeks.
Looking at the whole picture, it’s a bit of a quiet start with a whole lot of nothing for the first week. We've got a long gap of poor conditions through the end of August and into the first few days of September. Don't bother paddling out before then; it's mostly wind-affected mush, tiny swells, or cross/onshore slop.
The real standout – the one that actually gets the blood pumping – arrives on Saturday the 5th of September. White Rocks is the only break worth talking about here. While the overall forecast isn't a perfect 10, the combination of a solid swell and good wind makes it the pick of the bunch by a long shot.
Saturday morning the 5th is your window. We’ve got a solid 6ft swell out of the northwest, with a long 13-second period. This isn't your average windswell – it's got some serious groundswell grunt, with very strong combined wave energy (1110). The water's sitting at 60°, which is pretty normal for this time of year. That strong southerly wind is blowing straight offshore, which should keep the faces clean and lined up. For a spot like White Rocks that’s exposed to the northwest, this is a proper session. Afternoon has similar size but the period drops a touch and the wind swings cross-off, so the morning is definitely the prime pick. One thing to keep in mind: this spot can have crowds sometimes, so you might have some company in the lineup.
Before that? There's a brief flicker on Saturday the 29th of August morning – a 4ft NW swell but with a short 6-second period. It’s surfable but very ordinary. And on Monday the 31st of August, the swell actually builds to 6-6ft, but the wind is onshore and choppy, making it a messy paddle. From Monday the 7th of September, we get a big 8ft NW swell with a solid period again, but it’s cross-shore and lumpy – more of a mission than a pleasure.
For the absolute beginner, the 6ft on the 5th might be a bit of a handful; it's solid. But if you’ve got some experience, that Saturday morning is the only true window of quality in this outlook.
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.
