The Lowdown
Alright, grab your board and listen up. Rusty here with the outlook for The Three Bears.
Right off the bat, we've got some solid groundswell on the way, but it's going to tease us with a couple of days of dirty wind before it cleans up proper. This is a reef setup, so when it's good, it will be *really* good, but the crowd factor is a thing to watch – it can get *sometimes* busy out there.
Sunday the 13th is a write-off. We’ve got a strong 8ft to 8ft WSW groundswell with a long 14-15 second period, meaning plenty of energy pumping in. But the wind is howling onshore at 16 mph. It’s just a messy, unsurfable mess.
Monday the 14th is still a struggle. The swell drops slightly to 10ft in the morning, but the wind is cross-offshore. It’s a marginal call, so it’s a pass unless you’re desperate for a paddle.
Tuesday the 15th is the first real standout. That morning, the wind swings around to a clean offshore from the East at 16 mph, grooming a solid 8ft WSW swell with a 14-second period. The energy is still strong. The call is “excellent surf conditions for experienced surfers.” This is the one to circle. The afternoon gets a bit lumpy with a cross-shore, so get on it early.
The rest of the week is a bit of a washout with onshore winds and poor surf conditions, apart from a brief window on Wednesday the 16th afternoon where a 3ft swell goes glassy with a light breeze. It won’t be big, but it’ll be clean.
Looking ahead to Monday the 21st, that’s your second big standout. We’ve got a clean 8ft swell, but look at the period – 16 seconds of pure groundswell. The wind is a slight offshore breeze from the East, just 3 mph. This is a deep-water reef-buster. It’s going to be clean and powerful. Just remember, with a period that long, the sets will be more spaced out, and it might race a bit wide at this reef. For experienced surfers, this is a firecracker.
The last real highlight is the 25th of September – Friday morning. The swell bumps up to 12ft from the WSW with a 12-second period, and the wind is a clean cross-offshore from the SSE at 9 mph. This is pumping. It’s rated excellent for experienced surfers, but at that size, it’s strictly for the big-wave crew.
The water temp hasn't been flagged as unusual, so it should be about normal for this time of year around here.
So, to sum it up: get on it Tuesday the 15th for the first clean push, and then plan around Monday the 21st for the next solid, glassy session. Friday the 25th is for the big-wave boys.
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.
The Three Bears is 64 km (40 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
