The Lowdown
Alright folks, Rusty here. Let’s get stuck into the outlook for The Three Bears. It’s a reef break, consistent, and it usually handles a south-west swell best. The water temp is about average for the time of year, nothing too wild there.
The immediate forecast is a bit of a write-off, to be honest. We’ve got a solid pulse of swell coming in, but the wind is just terrible. For the first few days, from Monday the 31st of August right through to the end of the first week, we’re looking at onshore and cross-onshore winds in the 19 mph to 28 mph range. That’s going to chop it up and make it a real battle. The wave energy is high, but the quality is missing. It’s not worth paddling out for.
The pattern doesn’t really improve much through the start of the second week. The swell stays big, between 8 ft and 12 ft, but the wind is still a problem. There’s a brief moment on Tuesday morning, the 8th of September, where the wind drops to 9 mph and goes offshore. The swell is a solid 12 ft from the WSW with a very long period of 18 seconds, and the energy is massive. That has the potential for some big, clean lines, but the size and that long period mean it’s going to be a bit too much for beginners and the waves might be a bit straight for a reef. It’s an expert-only window.
The real standout, the one to circle on the calendar, is Saturday the 12th of September. The morning is looking mint. The wind will be light from the north at 9 mph, just off the shore, so the face will be clean as a whistle. The swell is a beast, 16 ft from the west, but the energy is enormous. The problem is, the forecast reckons it’s simply too big for this break. Even for experts, it’s going to be maxing out and dangerous. The afternoon is still big but a touch smaller at 15 ft, with a cross-onshore wind coming in, so still messy.
There is a last chance for a decent session right at the very end of the outlook. On Tuesday, the 15th of September, the swell drops right back to 6 ft from the WSW with a period of 14 seconds. The wind goes light from the NE at just 3 mph, crossing offshore. The energy is moderate. It’s the only time in the whole forecast that it’s labelled as excellent for experienced surfers. It’s a smaller, cleaner option after a long run of big, messy surf.
So, to wrap it up: the first two weeks are mostly a mess of big swell and bad wind. The only real chances are the expert-only window on the morning of Tuesday the 8th, and the much cleaner, smaller session on the morning of Tuesday the 15th. Don’t hold your breath for the rest.
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.

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.
