The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for White Rocks. We’ve got a 16-day window, and I’ve got to be straight with you—it’s looking pretty bleak for most of it. There’s a big gap of poor to no surf for the vast majority of the period, so don’t get your hopes up.
The only real glimmer of light comes in right at the start. On Wednesday morning, August 19th, we’ve got a pulse of 4ft swell from the WNW, with a period of 10 seconds. That’s a clean, moderate groundswell with decent energy (250). The wind is a light southerly offshore, which will keep it clean. This is the best on offer for the whole forecast, and it’s not huge. It’s a beginner-friendly break, so that size is fine, but don’t expect anything epic. The water temp is sitting at 60°, which is 2° warmer than average for this time of year, so it’s a bit on the normal side, nothing crazy.
The Wednesday afternoon session hangs in there with a 3ft swell, still from the WNW, but the wind goes light cross-off. It’s surfable.
After that, it’s a long, dry spell. From Thursday, August 20th, all the way through to the end of the forecast on September 2nd, the conditions are just poor. The swell drops off a cliff, and when there is any wave energy, it’s either onshore, weak, or both. We’re talking about a solid two-week stretch of flat, choppy, or windy junk. The wind swings onshore from the north for days, and the combined energy values are mostly in the double digits, well under 100. It’s not worth paddling out for.
If you’re desperate, the Wednesday morning is your only shot. After that, it’s a write-off. The waves, such as they are, are too small and the wind is wrong. For a beginner spot like this, it’s just a waiting game.
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.
