The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks at Lefthanders. This is a reef break that’s very consistent, exposed to the swell, and it’s a beginner-friendly wave. The water’s a touch warmer than normal for this time of year, sitting at 66°F.
We’ve got a serious run of big, powerful groundswell heading our way, but the catch is, for most of it, it’s just too much of a good thing. The first real standout is actually going to be right at the start, on Thursday the 27th of August. We’re looking at a solid 13ft swell from the SW with a very long period of 15 seconds. The combined energy is massive, clocking in at 6550, and the wind is a clean cross-offshore breeze. It’s a beautiful setup, but mate, that swell height is way over the 8ft mark. This is strictly for experienced surfers only. The wave energy is strong (6550), and with that long period, it’ll be a powerful, big-wave reef session. Beginners should stay well clear.
Thursday afternoon eases a touch to 10ft from the WSW, but still too big for the average punter.
Friday the 28th drops down to 8ft, and while the wind is still cross-off, the tide conditions look questionable. The energy is moderate (1757), but it’s a marginal call.
Now, here’s the good news for the weekend. Saturday the 29th of August is looking like the pick of the entire forecast. The morning shows a 7ft SW groundswell with a very long period of 16 seconds. The wind is light and cross-off from the ESE, so it’ll be glassy and clean. The combined energy is moderate (3512), and the conditions are dialed in for experienced surfers. This is the one to circle. The long period will make this reef break really stand up, offering long, clean walls. The afternoon gets bigger again at 10ft, but the wind swings to a light NE offshore, keeping it clean. If you’re an expert, the whole day is a winner.
Sunday the 30th is another big day, with 12ft in the morning and 10ft in the afternoon. The morning is clean with a light NE offshore, but the afternoon gets a light cross-on from the NNW. Still, for the experts, the morning session will be firing with very strong energy (6797).
After that, things turn ugly. From Monday the 31st of August through to the 5th of September, we’ve got strong onshore winds, lumpy conditions, and a lot of poor surf. The swell stays big, but with the wind all wrong, it’s a write-off. There’s a brief window on the 4th of September afternoon where the wind goes cross-shore, but it’s still messy.
The 7th of September, Monday morning, is another tease. We get a 13ft SW groundswell with that long period (15 seconds) and a clean cross-off breeze from the ENE. The energy is very strong (5984), but again, it’s a 13ft wave. That’s big, powerful, and not for the faint of heart.
The rest of the second week, from the 8th of September onward, is a mix of onshore winds, big swell, and poor conditions. The 10th of September has strong winds and rain, making it a total mess. The 11th of September finishes with choppy, lumpy, cross-onshore wind.
So, the bottom line: the standout is the morning of Saturday the 29th of August. That’s the one where the stars align for a clean, powerful, long-period swell at a manageable size. The 27th and 30th are for the big-wave crew only. The rest of the run is largely a windy, messy washout. If you’re not an expert, the window is very narrow.

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.
