The Lowdown
Alright, I’ll break it down for you in feet and knots. This is a rough one for White Rocks – a long, ugly stretch of almost nothing worth paddling out for. The wind’s gonna be your enemy most of the time, blowing cross-onshore from the NW, and the swell is either too small or too messy. Only one session stands out, and it’s a week and a half away, so don’t get your hopes up.
The water’s at about 59°F, which is normal for this time of year, nothing weird.
First week, from Monday the 20th through Sunday the 26th, it’s junk. Winds are cross-onshore at 15 to 18 mph, and the swell is tiny – under 3ft with a short, weak period of 5 to 6 seconds. The combined energy is pathetic, mostly under 100. It’s just choppy, lumpy, and a waste of time. No standouts.
Then Friday the 24th rolls in. That’s your one chance. Friday morning, the wind drops to a light cross-offshore from the WSW at 12 mph. The swell hits 5ft from the NW, with a 9-second period and a moderate energy of 321. The wave comment says “clean,” and it’s the best score we get. The afternoon gets messy again, so the morning session on Friday the 24th is the only window. The swell direction matches the optimum for White Rocks. It’s small but clean, and for a beginner spot, that’s the best you’ll get. Crowds might show up, but it’s a Friday morning with a marginal forecast, so you might have it to yourself.
After that, it’s back to garbage. Saturday the 25th has a bigger swell – 6ft from the NW with an 11-second period and a strong 712 energy – but it’s hammered by a 15 mph cross-onshore wind, making it a choppy, ugly mess. That’s too big for beginners and already blown out. The rest of the second week fades into tiny, weak swell, with occasional clean windows but no size. By the end, we’re talking 1.0ft to 1ft with almost no energy (6 to 28). The morning of Monday the 3rd of August has clean, cross-offshore wind and 3ft from the WNW, but it’s just too small.
So, bottom line: Friday the 24th morning is your only real shot. Everything else is a bust. Don’t bother unless you’re just looking to sit on your board.

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.
