The Lowdown
Alright folks, Rusty here. Let’s cut through the chatter and look at what’s coming our way for Rainbow Bay. It’s a bit of a slow start, but there’s a heavy pulse of energy building for the second week if you’ve got the patience and the quiver for it.
Right now, and for the next several days, it’s looking pretty flat and messy. We’ve got a sheltered point break here, so it takes a specific swell direction to really light it up, and the early part of the window is just not delivering. From Monday the 31st of August right through to the morning of Tuesday the 8th of September, there’s really nothing worth paddling out for. The swell is small, the winds are mostly onshore or cross-onshore, and the energy is weak. It’s a proper gap with no real recommendations. You’ll be staring at a lake-like surface for over a week. It’s the kind of stretch that tests your love for the sport.
Then, things start to get interesting. The afternoon of Wednesday the 9th of September, we see a sudden jump in size. The south-southeast swell pushes up to 10 ft, with a period of 10 seconds, and the combined energy is strong. The wind is fresh offshore out of the south, blowing clean. That’s 19 mph of offshore wind, which is a major positive for this sheltered setup. The water temperature is sitting at 69°, which is basically normal for this time of year, so no need to dig out the thickest rubber.
The real standout, the one you’re going to want to circle on the calendar, is the morning of Friday the 11th of September. The swell is cranking at 15 ft, coming from the southeast at 10 seconds, and the combined energy is a massive 4234. That’s very strong wave energy. The wind is a moderate offshore breeze at 12 mph, keeping things clean. The guidance says this is excellent for experienced surfers, and at 15 ft, that’s spot on. This is not for the faint of heart or the beginner. This is a big, powerful groundswell that will be breaking fast and heavy. Because it’s a point break, it should handle that size and direction well, but it’s going to be a serious session. The crowd profile notes that this spot is “often” busy, and with a swell like that, you can bet there will be a crew out. Prepare for a lineup.
The rest of that week stays solid, with the swell slowly easing down through the 10 ft range over the weekend of the 12th and 13th, still with clean cross-off winds. By the 14th and 15th of September, the energy drops back off, and the winds start to pick up again, so the window of opportunity is really focused on that big pulse mid-week.
So, the call is simple: save your energy for the 9th of September onwards, but the absolute peak, the one to chase, is Friday the 11th of September. It’s a big, powerful, and potentially perfect setup for those who can handle it. Don’t blink.
Rusty.

Information about the Rainbow Bay Surf forecast
The above surf forecast table for Rainbow Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rainbow Bay can be found by selecting the local surf guide option on the grey menu. Our Rainbow Bay 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 (Rainbow Bay) 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 Rainbow Bay 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.
Rainbow Bay is 6 km (4 miles) from Banora Point. If you plan a holiday in Gold Coast, look for hotels and other accommodation in Banora Point. Banora Point has rooms for a wide range of budgets as well as car hire and transport links.
