The Lowdown
Alright, Rusty here, checking in. Let’s talk about Lefthanders.
The outlook for the next 16 days is a real mixed bag. We’ve got a massive, powerful groundswell setting in, but it’s going to be too big for this break for a long stretch. The real window for a good session is a specific, narrow window early next week.
The water is sitting at 67°, which is *much warmer than normal* for this time of year, so you can leave the thick suit at home.
The first chance to even think about paddling out starts on Friday afternoon, 31st July, but don't bother. We’ve got a 13ft SW swell with a 19 mph westerly wind. That’s onshore junk. The combined energy is a massive 7564 – plenty of power, but it's all messy. Pass.
Saturday the 1st and Sunday the 2nd of August keep the big swell going, but the wind turns cross-offshore. The problem is that the swell is predicted to be too big for this break. Saturday morning is 13ft, Saturday afternoon jumps to 16ft and Sunday holds at 12ft and 10ft. The energy is still huge (10760 on Saturday afternoon). No good for a paddle.
Now, here’s the standout. Monday morning, the 3rd of August. That’s the one. The swell drops to a much more manageable 6ft from the SW, and the period is a very long 15 seconds. This is proper groundswell. The wind is glassy – as light as it gets at 3 mph from the NNE. That’s a major positive. The forecast says excellent surf conditions for experienced surfers. The combined energy is still a solid 1575, so there’s power. For a reef break like Lefthanders, this long-period swell is perfect. It’ll bend and wrap in beautifully. It’s a very consistent spot, so you’ll get waves. The downside? It’s often crowded, so bring your patience.
Monday afternoon drops off a bit with a 7ft swell and onshore wind, so hit the morning session.
Tuesday the 4th is a write-off. Strong onshore winds and an 12ft swell. Poor conditions.
Wednesday the 5th of August morning is another one to watch, but it’s a big step up in size. We’re looking at 15ft from the SW with a 16-second period. The wind is cross-shore from the NNW. The forecast says wind and tide favorable, but the swell is predicted to be too big for this break. The energy is 10754. For experienced surfers only, and even then, it’s pushing it. The rest of that week and into the second week is a parade of massive, dangerous surf. From Thursday the 6th through to Saturday the 15th of August, the swell fluctuates between 13ft and 28ft, often with strong or gale-force winds. The energy values go through the roof, hitting 44885 on the 9th and 53715 on the 15th. That’s beyond dangerous for a paddle. If you’re a kite surfer, the setup from the 5th onwards might be more interesting than surfing.
So, the bottom line: Monday morning, the 3rd of August, is your best bet. Glassy, clean, and a solid 6ft groundswell. Get it while it’s good.
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.
