The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, it’s a pretty grim outlook for the next couple of weeks. We’ve got surf, sure, but the conditions are mostly a mess. The wind is the main problem – it’s just relentless, and it’s rarely blowing in our favour. The first solid wave energy doesn’t really show up until the 12th of September, but even then, it’s a struggle.
The one spot we’ve got to look at is White Rocks. It’s a beginner-friendly, fairly consistent beach break that’s exposed to the northwest swell. The water temp is sitting at 60°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your toes off.
The first few days are a write-off. Monday the 7th has a bit of swell at 4 ft from the WNW with a period of 10 seconds, but that 19 mph cross-off wind from the WSW is just ruining it. The energy is weak at 389. Tuesday the 8th gets a big pulse of energy – 10 ft from the NW, period 10 seconds, and the combined energy is a whopping 2093 – but it’s a lost cause with 28 mph cross-on wind. That’s a mess.
Wednesday the 9th is small and windy, Thursday the 10th has a tiny 2 ft clean wave with a fresh offshore, but it’s barely enough to get excited about. The energy is only 88. Friday the 11th is a no-go.
Now, Saturday the 12th of September is the one day that stands out. We’ve got a 6 ft NW groundswell rolling in with a long 13-second period. The combined energy is a solid 1053, so there’s some proper push. The wind is a fresh offshore from the SSE, which means the faces will be clean. It’s a bit of a beast for beginners, but for the crew that can handle it, this is the best we’ll see. The period is long enough that the waves will have shape, and the gaps between sets will help with the paddle out. The Saturday afternoon drops to 5 ft with the same clean wind, still a decent option.
After that, we’re back to small, choppy, and mostly cross-onshore dross for the rest of the week. The 17th and 18th of September have a few tiny, clean waves but they’re barely ankle-snappers. The energy is around 64 to 139. The 20th of September sees a 5 ft WNW swell with a 12-second period, but the cross-shore wind from the west is going to chop it up. The energy is 518, but it’s just not clean enough.
The 22nd of September looks like a write-off again with a 8 ft NW swell and 31 mph cross-shore wind. That’s a kite session, not a paddle session.
So, the bottom line: if you’ve got a board and a window, the only real window is Saturday the 12th of September at White Rocks. Get it while you can, because the rest of the 16 days is a long, frustrating wait.

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.
