The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for Lefthanders. We’ve got a solid run of swell on the way, but the trick is going to be finding windows where the wind and the size line up for a proper paddle. The water's sitting at about 64°, which is a touch warmer than usual for this time of year – just a degree off the norm, so it’s a nice welcome for that first duck dive.
The real standout window is shaping up for Wednesday the 16th, first light. We’ve got a 8ft swell rolling in from the SW with a 16-second period – that’s proper groundswell, full of push and shape. The wind is light and cross-off from the NNE, so it’s going to be clean. This is prime for experienced surfers, as that size is up there. The wave energy is strong at 2944 (moderate energy), and for this break, the swell direction matches up nicely with what it loves. It won’t be empty – crowds are likely here – but the quality is the best on offer.
Before that, things are a bit of a mixed bag. Thursday afternoon the 10th and Friday morning the 11th have waves, but the quality is marginal with afternoon cross-shore winds and a morning breeze that’s too fresh from the NNE at 30 km/h, making it bumpy. Friday afternoon the 11th looks cleaner on paper with a 10ft swell and 18-second period from the WSW, but the combined energy is very strong (4882) and that size is getting up there; the wind is cross, not ideal, so it’s a maybe for the keen.
Saturday the 12th through Sunday the 13th is a write-off for surfing – onshore wind trashes the shape with 7ft to 12ft swells. Those days are a solid pass.
Monday the 14th brings a massive 13ft SW swell with a clean offshore E wind in the morning, but honestly, that’s too much for this spot. It’s a kite surfer’s dream, not a paddle surfer’s. The same goes for the rest of that week – huge swells, clean winds at times, but all over 8ft and often 12ft, so expert-only territory at best.
Toward the end of the window, around Monday the 21st and Tuesday the 22nd, we see some truly monstrous energy – we’re talking combined energy values of 8972 and 12133 (strong to very strong). These are 15ft to 20ft swells with cross or onshore winds. That’s big-wave territory, not for your average session.
There’s a bit of a gap in quality surf from the 17th through the 20th, with onshore winds and messy conditions, before another push of energy at the very end. The morning of Wednesday the 16th remains the top call – it’s the one session in this whole 16 days where everything clicks for a normal-sized, clean, powerful wave. Get on it if you can.
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.
