The Lowdown
G'day, Rusty here, checkin' in on the surf outlook for White Rocks. Let's get into it.
Alright, so the start of the run is a bit of a mixed bag. The first real sniff of decent surf is on Saturday the 5th of September. We've got a clean 4ft wave from the NW at 10 seconds, with light W-NW winds going glassy. The water is a touch warmer than normal for this time of year, sitting around 60°. The combined energy is moderate (303). It's a decent option for a beginner, but the crowds can be a factor here sometimes. After that, it gets a bit grim. There's a solid gap from late Sunday the 6th right through to the end of the following week, with a whole lot of poor surf conditions and onshore junk. Big, messy, wind-affected swell, and a lot of it is too big for the average punter, over 8ft for a few days. Not worth paddling out for.
Then, we get a bit of a light at the end of the tunnel. The best of the lot is shaping up for Thursday the 17th of September. The morning is looking choice with a 7ft NW swell at 10 seconds, and glassy conditions with a light S wind. The wave energy is strong (993). That's a solid offering, but it's a bit of size, so it's for the experienced crew. The following morning, Friday the 18th, is also a standout with a clean 6ft NW swell at 11 seconds, light offshore winds, and glassy conditions again. The energy is still strong (792). That's a proper session waiting to happen. The weekend after that, the 19th and 20th, looks fun and clean with offshore winds and smaller 3ft to 5ft waves, perfect for a longer board.
All in all, the first week is a write-off after the first Saturday, but the second week has some promise. Keep an eye on the 17th and 18th of September - that's your best bet.
Rusty.

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.
