The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, I gotta be honest with you – the next couple of weeks are looking pretty grim for a proper paddle. The only break on the radar is White Rocks, and even then, it’s a real struggle to find a window that’s worth getting wet for. The whole 16-day forecast is a long, flat stretch of tiny, weak waves and messy wind, so don’t get your hopes up for any hero sessions.
We start off on Tuesday the 11th of August with nothing doing. Tiny 1ft NW swell with a short 7-second period, and a cross-off wind keeping it clean, but there’s just no power there. The combined energy is a measly 22 – that’s barely a ripple. This poor run continues all the way through to Saturday the 15th. The swell stays below 3ft, the wind is all over the place, and the water temp is sitting at 59°, which is pretty normal for this time of year.
Now, things finally get a little interesting on Sunday the 16th of August. The morning brings a 3ft NW swell, and the wind swings light offshore from the south. That’s clean, but the period is still short at 8 seconds, and the energy is only 96 – it’s surfable, but you’ll be working for it. The afternoon is a bit cleaner with a gentle offshore, but it’s still small at 3ft.
The real standout, if you can call it that, is the morning of Sunday the 23rd of August. This is the only moment in the whole run that scores a “good surf conditions” call. We’ve got a 4ft NW swell with a 10-second period, and the wind is a light offshore from the SSW. That’s clean, and the combined energy is a solid 306 – moderate, but better than anything else. It’s the best on offer, but don’t expect a big, powerful wave.
Before that, there’s a big spike on Wednesday the 19th of August. The afternoon shows a 8ft WNW swell with a long 14-second period, and the energy is massive at 1865. But the wind is a cross-on from the northwest, which is going to chop it up. That’s a lot of power, but it’s not going to be clean. For a point break or reef, that long period would be a dream, but White Rocks is an exposed beach break, and that combo will likely make it a messy, closed-out mess. That’s more for the experienced crew if they’re desperate, but for a beginner, that’s a no-go – anything over 5ft is too much.
Honestly, if you’re looking to paddle, save your energy for Sunday the 23rd. It’s the only clean, surfable day. The rest is a bust. If the wind holds, the setup on the 19th might be more interesting for a kite session than a paddle.

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.
