The Lowdown
G'day, Rusty here, and I gotta be straight with you – the outlook for Rainbow Rocks is a bit of a mixed bag. For the next few days, we're looking at some pretty poor conditions, with a lot of cross-onshore wind making things choppy and messy. The water temp is sitting at 57°F, which is pretty much normal for this time of year, so no surprises there.
The real standout window is Thursday the 3rd of September. That afternoon, we get a glassy session with the wind dropping right off, and a solid 7ft swell rolling in from the WNW with a moderate 11-second period. The combined wave energy is a solid 1444 (moderate energy), and the conditions are described as excellent for experienced surfers. This is the pick of the bunch, no question.
The following week has some potential, but it's less certain. Thursday the 10th of September morning sees a clean 6ft WNW swell, pushed by a cross-offshore breeze, but it's a strong 25 km/h wind, so it'll be a bit wild. The combined energy is 1215 (moderate energy). Then, on Saturday the 12th of September, we get another glassy morning with a 6ft NW swell, but the period is short at 9 seconds, so it won't have much punch. That afternoon, the swell jumps up to 10ft from the NW, which is proper big and only for the experts, but the wind is onshore so it'll be a bit lumpy.
Overall, if you're keen, Thursday the 3rd is your day. The rest of the window is a bit of a gamble, with a lot of marginal conditions and some strong winds making it more of a kite-surfing scene than a clean paddle-surfing one. Keep an eye on the forecasts, but for now, that Thursday afternoon is the standout.
Rusty.

Information about the Rainbow Rocks Surf forecast
The above surf forecast table for Rainbow Rocks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rainbow Rocks can be found by selecting the local surf guide option on the grey menu. Our Rainbow 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.

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 Rainbow 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.
