The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Lefthanders.
Right off the bat, we’ve got a solid pulse of swell heading our way, but it’s gonna take a few days to really clean up and become truly surfable. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year, so the spring suit might feel a bit more comfortable than usual.
The first few days are a bit of a write-off, honestly. Sunday the 23rd is a non-starter. We’ve got an 8ft SW swell, but it’s coming in with a 12 mph cross-onshore wind, making it choppy and messy. The combined energy is moderate (2766), but the conditions just aren’t there.
Monday the 24th is a tease. The morning session shows a 10ft SW swell with a 9 mph NW cross-on breeze. The forecast says the swell is too big for this break, and the wind is not helping. It’s a gentle cross-onshore, so it’s fairly choppy. The afternoon only gets worse.
Tuesday the 25th is a total no-go, with strong winds and rain. The swell is pulsing, but the wind is howling. Forget it.
The real standout, the one you’ve been waiting for, is Wednesday the 26th. This is the big one. We’re looking at a massive 18ft WSW groundswell with a very long period of 18 seconds. The combined energy is through the roof at 19143. The morning is clean, with a light 6 mph SSE cross-offshore breeze. The water is going to be a wild, powerful beast. This is strictly for experts only. The size and power will be intimidating, and that long period means it’ll be fat and fast, best left to those with serious skills. The afternoon stays clean, but the size is still 16ft.
Thursday the 27th is another one for the experienced crew. An 12ft SW swell with a 15-second period is still pumping (5785 energy), and the wind is a clean cross-offshore from the SE at 19 mph. It’s clean, but the power is still very real.
Friday the 28th is where it starts to get a bit more manageable. The morning is a highlight. We’ve got a 8ft SW swell, and for the first time, we get a proper offshore wind from the East at 12 mph. The conditions are clean. This is excellent surf for experienced surfers – the swell is still a bit big for beginners, but it’s a much better prospect. The afternoon drops to 6ft with a cross-offshore, but it’s a bit marginal.
Saturday the 29th morning offers an 8ft SW swell with a 16-second period and a clean cross-offshore NE wind. The energy is still high (4083), but the conditions are clean. This is a solid option for the experienced surfer.
Sunday the 30th through to Monday the 31st sees the swell staying in the 10ft to 12ft range, but the wind clocks onshore or cross-onshore, ruining the quality. The size is still too big for this break, and the wind makes it a mess.
September 1st onwards is a long stretch of poor conditions. The swell is still there, but the wind is onshore or cross-onshore and strong, making it lumpy and choppy. The forecast is bleak right through to September 7th, where we see another huge pulse of 23ft to 25ft+ swell, but with onshore winds. It’s colossal, but it’s a mess.
The Best Bet: No doubt about it, Wednesday the 26th is the session to circle. The sheer size and power are the highlights, but only for the elite. For the rest of us, Friday the 28th morning is the best balance of size and clean conditions. Get out there early.
Rusty.

Information about the Lefthanders Surf forecast
The above surf forecast table for Lefthanders provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lefthanders can be found by selecting the local surf guide option on the grey menu. Our Lefthanders 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 (Lefthanders) 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 Lefthanders 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.
Lefthanders is 87 km (54 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.
