The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
It’s a bit of a slow start around here, with the first few days looking pretty ordinary. The signal is weak, but we’ve got a couple of windows that might just be worth paddling out for.
The main event looks to be Saturday, August 8th, at White Rocks. We’ve got a solid 4ft swell rolling in from the WNW, with a period of 10 seconds – that’s a proper groundswell with some punch. The combined energy is up at 235 (moderate), and the real kicker is the wind: a moderate offshore breeze from the south. That’s going to keep the faces clean and lined up. It’s a consistent spot, so you can expect a few waves. The water temp is sitting at 59°, which is pretty much bang on average for this time of year, so no surprises there. This is the standout session of the whole forecast.
The afternoon of Saturday the 8th holds up just as well, with the same 4ft, 10-second swell and 240 (moderate) energy, still under that clean offshore flow. This is your best bet.
Now, there’s a long gap after that. Through the rest of the week and into the next, it’s mostly small, weak, and messy. We get a tiny blip on Monday, August 10th, with a glassy 2ft pulse from the NNW, but it’s very weak at 100 (moderate), and the energy will be hard to ride. Not really worth rushing for.
Looking further ahead, towards Wednesday, August 19th, there’s a glimmer of hope. The morning shows a 3ft, 11-second groundswell from the WNW, with 198 (moderate) energy. The wind is cross-off, keeping it clean. Then the afternoon of the 19th gets interesting: a 4ft swell from the NW with a 11-second period, pushing 273 (moderate) energy, and a moderate offshore wind from the SSW. That’s a decent setup, but it’s a long way out, so treat it as a promising possibility rather than a sure thing. The water temp anomaly is normal, so no weird currents expected.
Sunday the 16th through Tuesday the 18th is mostly a write-off – small, windy, or cross-on. The conditions don’t really get good again until that late-August window.
So, bottom line: if you’re keen, make the most of Saturday the 8th. It’s the clear winner. Everything else before that week-and-a-half gap is a gamble, and the later stuff is a wait-and-see game.
Stay safe out there.

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.
