The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.
Honestly, the next week and a half is a bit of a write-off. We’ve got a fair gap of poor conditions before anything really worth paddling out for shows up. The first proper surf worth mentioning is a bit of a tease, but it’s a long way off.
The first real glimmer of hope comes on Monday the 24th of August. The swell is coming from the NW at 4ft, with a long period of 11 seconds – that’s proper groundswell energy. The winds are light offshore from the SSE, so the face will be clean. The water temp is sitting at 60°F which is about normal for this time of year. The combined energy of all swells directed here is moderate (357). That Monday morning session at White Rocks is the standout option in the whole window. It’s not huge, but it’s the best we’ve got.
Now, if you’re patient and can wait even longer, there’s another one to keep an eye on. Later on Monday the 31st of August, the swell bumps up to 6ft from the NW, but the period drops to 7 seconds. That’s a short-period wind swell, and with the wind staying light and cross-offshore, it’ll be clean but a bit lumpy. The energy is moderate (293). That’s a bit of a gamble, but if you’re desperate for a wave that’s bigger than a ripple, it’s an option. Then, into Wednesday the 2nd of September, the morning looks clean again with a 4ft NW swell at 8 seconds and a gentle offshore breeze. The energy is moderate (203). It’s getting into the second week, so treat these long-range calls with a grain of salt, but I’d be watching that 2nd of September morning.
So, the call is: there’s some decent, clean, smaller surf on offer, but it’s mostly a waiting game. The best bet is that Monday the 24th morning session. For the rest, it’s a lot of blown-out, messy, or just tiny conditions. The water’s about average for the time of year.
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.
