The Lowdown
Alright, let’s break it down in feet and miles per hour, partner.
So, for White Rocks, we’re in a dry spell. The water’s about 60°F, which is a bit above where we’d expect this time of year, but that don’t help you on a flat day.
Starting Friday August 28th, it’s tiny and junk. Waves barely a foot, onshore winds, and the combined energy is laughable—single digits to low 20s. Not a thing to ride. Saturday and Sunday clean up a bit with offshore breezes but the swell is still barely knee-high.
Monday the 31st is more of the same: messy, chop, waves around 3 to 3 feet, onshore winds. No good. Tuesday September 1st sees a bit more size—up to 5 to 6 feet from the WNW—but the wind is cross-shore at 12-16 mph, so it’s lumpy and choppy. Combined energy hits the 300s, so there’s some power, but the surface is rough.
Wednesday September 2nd is our first real chance. Morning has offshore wind at 9 mph, 3-foot waves from the NNW, period of 8 seconds, and combined energy of 133. Conditions are clean. It’s surfable, but not a standout. Just a sign we’re not completely dead.
Then we go back to junk until Friday September 4th afternoon. That’s the one. Swell builds to 6 feet from the WNW with an 11-second period—real groundswell—and combined energy of 736. Winds are super light from the SSW at 3 mph, making it glassy. This is your best session in the whole 16 days. It’s a clean, powerful wave for the experienced crew. Beginners might find it a bit much.
Saturday the 5th is bigger: 8 feet in the morning from the NW (energy 1325), but with cross winds at 16 mph—that’s expert-only and choppy. Afternoon drops to 6 feet but still cross winds. Not the clean power we saw Friday.
After that, it’s mostly small (under 4 feet), with onshore or cross winds and low energy through the rest of the forecast. Tuesday the 8th has a 7-foot bump from the NW again, but it’s marginal quality and gets choppy.
In short: one killer afternoon on September 4th. The rest is a waiting game. Keep an eye on that date.

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.
