The Lowdown
Alright, surfers, Rusty here. Let’s cut through the noise and look at the next couple of weeks for The Three Bears. We’ve got a mixed bag coming our way, so let’s break it down day by day.
The outlook starts off a bit messy. We’ve got a solid pulse of west-southwest groundswell, but the wind is going to be a problem for the first few days of the run. It’s not until Friday the 21st that things finally line up, and that’s when you’ll want to be in the water.
The first real highlight of the period is Friday, August 21st. The morning sees a clean 10ft WSW groundswell (4281 combined energy) with a moderate offshore east-northeasterly breeze, making for excellent conditions for the more experienced surfers in the lineup. The Three Bears (Big Island) is a reef, so this long-period swell at 15 seconds should wrap nicely. But the afternoon is the real standout: the wind drops to glassy with a slight air, the swell is still a solid 10ft, and the period stretches to 17 seconds. The energy jumps up (5406), and the forecast is calling for exceptional surf. This is as good as it gets in this window – clean, powerful, and lined up. If you’re an expert, this is your session.
Following that, Saturday the 22nd is another good one, with cleaner conditions. The swell eases a touch to around 7ft in the morning and 6ft in the afternoon, but it’s still that consistent west-southwest groundswell (1670 and 1283 energy). The wind is either a gentle cross-off or glassy calm (that’s right, zero wind), keeping the surface smooth. This is a great day for the experienced crowd, just a bit smaller than Friday.
Sunday the 23rd still has decent surf, around 6ft, with a moderate offshore breeze in the morning keeping it clean (1568 energy). Afternoon gets a bit of a light cross-on breeze, making it a touch bumpy, but still rideable.
Now, after that run, we hit a rough patch. Monday the 24th through Thursday the 28th is a write-off. Strong cross-shore winds, blown-out conditions, and the swell drops right off into the 4ft to 8ft range. The energy also takes a big hit. The conditions are poor, and honestly, it’s not worth getting wet. That’s a full four-day gap with no good options.
The window closes with another promising blip at the very end of the forecast. Saturday, August 29th in the morning looks all-time on paper. A clean 10ft WSW swell with an 18-second period and a light offshore east-northeast breeze (5497 energy). This is a very long period groundswell, so at a reef like The Three Bears it should produce some beautiful, powerful lines. This looks like another standout, but we’re pushing 10 days out, so treat it as a promising look rather than a sure thing.
The following day, Sunday the 30th, is interesting too. The swell jumps up again, with 12ft and 13ft WSW swells (7087 and 8542 energy) and very light winds. The issue here is the period is a bit shorter (16s) and the swell is getting big. This is getting into expert-only territory, and the tide will be a factor. It’s got potential, but it could also be a beast.
So, to wrap it up: The first real window is Friday the 21st through Sunday the 23rd, with Friday afternoon being the pick of the bunch. Then it goes flat and messy for a few days. The long-range look for the 29th and 30th is exciting, but we'll need to see how it all comes together.
Stay safe out there, and don't forget your wetsuit.
Rusty.

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.
