The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for The Three Bears. This is a reef break, exposed to the swell, and it’s a consistent spot which is a good start. The water temp is sitting at 64°, which is about average for the time of year, so nothing wild there.
The outlook kicks off Thursday morning, the 10th, but to be honest, it’s a bit of a frustrating start. We’ve got a solid 5ft swell from the WSW with a very long, groundswell period of 15 seconds, and the combined energy is moderate (1111). The problem is that stiff 19 mph NE wind, which is cross-offshore, is making it choppy and messy. The afternoon is a different story though. The wind drops right off to a glassy 3 mph from the NNW, and the swell stays clean. It’s a real highlight for the experienced surfer, but the wave comment flags that it’s for experienced surfers only, so don’t expect a beginner-friendly wave here.
Friday the 11th is a bit of a letdown. The morning has a slightly bigger 5ft swell, but that 19 mph NE wind messes it up again. The period is still very long at 15 seconds, keeping that groundswell energy high (1938), but it’s not clean. The afternoon gets worse as the wind turns onshore from the north, making it lumpy. Saturday the 12th and Sunday the 13th are a write-off. The swell jumps to 8ft, but it’s blown out by strong onshore winds, so the surf quality is poor. Not worth paddling out for.
Now, Monday the 14th is a standout. The swell is a solid 10ft from the WSW with a period of 14 seconds, and the combined energy is strong (3334). The wind is a gentle offshore breeze from the east at 9 mph, making for clean, well-shaped waves. This is a big day, and at 10ft, it’s definitely for experienced surfers only. The morning is the pick, with the wind holding offshore. The afternoon sees the wind swing to the southwest, turning cross-onshore, so the window is tight.
Tuesday the 15th is also good. The swell drops to 8ft, and the wind is a light cross-offshore from the southeast at 6 mph. The morning is clean and the wave energy is still strong (2408). The afternoon gets a bit bumpy again with a moderate cross-shore. Wednesday the 16th is another glassy morning, with a 6ft swell and a long period of 17 seconds. The wind is a mere 3 mph from the WNW, so it’s glassy. The afternoon turns onshore, but the morning is a real treat.
After that, Thursday the 17th and Friday the 18th are a mess. Strong winds, some rain, and poor surf quality. The swell drops and the wind picks up, making it a no-go.
Then, hold onto your board, because Saturday the 19th is a monster. There’s a massive 20ft swell from the west with a period of 14 seconds. The combined energy is very strong (14439). The wind is light onshore from the west, but at 20ft, this is only for the truly experienced and is a very serious, big-wave day. It’s a high-risk, high-reward situation. Sunday the 20th is still big at 8ft, but the wind is a clean cross-offshore from the north-northeast, making it a much more manageable session.
The following week, from Monday the 21st to Wednesday the 25th, there’s a mixed bag. The 21st has an 12ft swell from the WSW with a very long period of 17 seconds, but the wind is a moderate cross-onshore, making it choppy. The 22nd and 23rd see cleaner conditions with offshore winds, but the swell stays around 7ft to 10ft. The 24th has a clean morning with a 7ft swell and a 16-second period, making for a nice, powerful groundswell. The 25th also has a clean morning with a 6ft swell.
The best of the whole window is the morning of Monday the 14th of September, with that 10ft swell and clean offshore wind. The Saturday the 19th is a massive, once-in-a-blue-moon swell, but it’s only for the dedicated big-wave crew. The glassy morning of the 16th is also a top pick.
Rusty, signing out.

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