The Lowdown
Alright, g’day crew, Rusty here. Let’s have a look at what’s cookin’ for White Rocks.
To be honest, the next week and a half looks pretty grim. We’ve got a long stretch of junk from Tuesday the 4th all the way through to Saturday the 15th, with nothing worth paddling out for. Lots of poor surf conditions, messy wind, and small weak swell. You’ll be watching the ocean do nothing much.
Monday the 17th of August is the one bright spot on the horizon. We’ve got a solid swell coming in from the NW at 6ft, with a nice long period of 11 seconds – that’s proper groundswell energy. The combined energy hits 712 (moderate-strong), so there’s some grunt in the water. The wind is offshore from the south at 9 mph, so it’s going to be clean, with smooth faces. This is definitely the standout of the whole 16-day window. The water temp is about average for this time of year, so nothing unusual there. The Tuesday afternoon holds up too, with 5ft NW swell and light offshore breeze, so you’ve got a solid day and a half if you’re keen.
White Rocks is a beginner-friendly spot, fairly consistent, and exposed to the NW. The swell direction lines up perfectly with the optimum, so expect those waves to wrap in nicely. Crowds are possible here sometimes, but on a Monday morning with a bit of size, you might get a few locals out. The 6ft is a bit of a step up from the tiny stuff, so it’s good for most intermediates – beginners might find it a little punchy.
The rest of the window? Sunday the 9th of August morning has a little pulse from the NW at 5ft, period 10 seconds, and a light WSW breeze giving clean conditions, but the score is just not there. It’s a marginal call at best, not a true standout.
So yeah, hang tight. The first week is a write-off. Monday the 17th is your window. That’s the one.
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.
