The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking.
Honestly, mate, it’s a pretty flat and forgettable stretch for White Rocks. We’re staring down a full 16 days with barely a ripple worth getting wet for. The opening Sunday morning on the 16th of August offers a tiny 2 ft NW swell, but the real issue isn’t the size—it’s the 60 (weak) combined energy. The water’s sitting at a warm 60°, about 2° above normal for this time of year, so it’s a touch toastier than usual. That morning, the wind is a clean offshore from the S at 9 mph, so it’ll look okay, but the waves are just too weak to get excited about. The whole rest of that day and the next are a write-off with poor conditions.
We then hit a dry spell. From the 18th through the 29th of August, it’s pretty much all poor surf or marginal at best. The combined energy does jump up on the 19th to 785 (moderate) with a 6 ft WNW swell, but the wind is a messy cross-off at 19 mph, and the rating tells me it’s still just marginal. That’s not worth paddling out for. There’s a grim run of onshore winds from the N and NNW from the 20th to the 24th, blowing that small swell to bits. Nothing to see here.
The only faint glimmer comes right at the tail end: Monday morning, the 31st of August. We get a 3 ft NNW swell with clean offshore wind from the S at 12 mph. The combined energy is still only 59 (weak), and the period is a short 5 seconds, so it’ll be a bit lumpy and gutless. But if you’re desperate for a slide, that’s your best chance. It’s a beginner-friendly wave at 3 ft on a fairly consistent break, and crowds are only sometimes a problem, so you might have it quiet.
Otherwise, it’s a long, quiet wait. For an area where consistent surf is on the table, this is an unusually flat run—but forecasts can change.
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.
