The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ at White Rocks.
First off, it’s a pretty quiet picture. There’s not a whole lot to get excited about for the first ten days or so. White Rocks is a beginner-friendly, exposed NW spot, and right now the swell energy is just plain weak. Most of the time we’re looking at combined swell energy readings well under 100, often in the low double digits—that’s barely a bump. The water temp is about average for this time of year, nothing wild going on.
We kick off Monday the 10th with a tiny 3ft NW swell, 8-second period, only 90 energy, and cross-shore winds. It’s poor and not worth paddling out. Tuesday the 11th drops even smaller, with 1ft at best. Wednesday and Thursday have clean offshore winds but the swell is pathetic – 0.7ft to 1.0ft. That pattern sticks. The whole first week is a washout.
Friday the 16th afternoon actually goes glassy for a moment – calm wind, 2ft NW, but the energy is only 48 and it’s still rated poor. Tempting but not really gonna deliver.
Then we hit a little blip on Tuesday the 19th morning. There’s a 5ft NW swell, 11-second period, and the combined energy jumps to 515 – that’s moderate energy. Winds are cross-shore and light. The rating is still marginal, not epic, but it’s the best the whole run has to offer. That’s your one potential standout in the whole outlook. It’s about two weeks out, so less certain, but if you’re keen, keep an eye on it.
After that, things fade again. Thursday the 20th has strong onshores and messy surf. By Friday the 21st afternoon, we get a clean little 2ft NW with 51 energy, surfable but very ordinary. The rest of the run into the 25th is tiny and onshore again.
Honestly, there’s a big gap of dead days here. If you want to surf, the 19th morning is your only real hope, and even that’s marginal. It’s not a great run for White Rocks.
Stay patient, mate.

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.
