The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for this stretch.
Alright, let’s be straight with you—this is a tough run. The first week and a half is mostly a write-off with poor surf conditions at White Rocks. We’ve got a long gap of over a week with no real surf on offer. The wind is messy, the swell is small, and it’s just not worth paddling out for most of it. The water temp is sitting at 59°, which is about average for this time of year.
The first real glimmer of hope shows up on Monday, August 10th. That’s the standout. The morning brings a 5 ft NW swell, period around 9 seconds, with a light SSE breeze holding cross-off. That’s clean. The combined energy is moderate (325). Then in the afternoon it goes glassy, with a 4 ft NW swell and the same moderate energy (287). That’s the best-looking window of the whole forecast. The wave comment says “expect good surf conditions,” and I’d agree. It’s not huge, but it’s clean and rideable.
The next real chance is on Sunday, August 16th, but it’s a bit of a mixed bag. The morning is glassy with a 5 ft NW swell, but the period is short at 6 seconds, and the energy is moderate (123). The afternoon sees the swell jump to 7 ft NW, but it’s cross-on with a light ENE breeze, and it’s borderline messy. That’s expert territory size-wise, but the wind isn’t doing it any favours.
Monday, August 17th, has a clean morning with offshore winds and a 5 ft NNW swell, but again, short period (6 seconds) and moderate energy (145). It’s surfable, but not a standout.
Honestly, if you’re picking a session, make it Monday, August 10th. The glassy afternoon is the best of the bunch. The rest of the run is either flat, messy, or only for the dedicated.
Stay patient, and keep an eye on the forecasts.

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.
