The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got in the water for the next couple of weeks.
First up, we’re looking at Lefthanders. This is a reef setup, and it’s very consistent, so it’s always worth checking. The water temp is about average for this time of year, nothing crazy to report, just your usual tropical temps.
The pattern for the next 16 days starts with a bit of a mixed bag. We’ve got consistent swell, but the problem is the size. From Thursday the 10th through the morning of the 11th, we’re seeing clean lines with a 7ft to 7ft SW swell. The wind is light and cross-offshore, which is good. But the combined energy is already high, reading 2327 and 3401, showing there’s plenty of power in the water. The period is long, 14 to 16 seconds, which means groundswell with good shape and energy. This is a good window for a solid session, but the swell is already pushing 7ft, which is getting a bit much for total beginners.
Then, Friday afternoon the 11th, things get heavy. The swell jumps to 10ft from the WSW, with a 18-second period. The combined energy is massive at 4741. The wind is cross-shore, but at this size, it’s really only for experienced surfers. It’s a powerful, groundswell-driven wave, and it’s going to be a handful.
From Saturday the 12th all the way through to the afternoon of the 16th, the conditions are pretty much a write-off. The swell is consistently over 8ft, and for most of that time, the wind is onshore or cross-onshore, making it lumpy and messy. The combined energy values are through the roof, well into the 3000 to 5000 range, but the wind is just ruining it. Saturday morning the 12th is a total loss with onshore wind and 8ft swell. Saturday the 19th afternoon sees a slight improvement, but it’s still marginal with a cross-chop.
The best standout in this whole period is actually Thursday morning the 10th. The wind is a light cross-offshore from the NE at 16 mph, and the swell is 7ft from the SW with a 14-second period. The combined energy is high at 2327, but the conditions are clean. It’s a strong, powerful reef wave, but it’s manageable if you’re competent. The crowds are often present here, so expect company.
For a second option, look at Monday morning the 14th. The swell is a massive 13ft from the SW with a 14-second period, and the combined energy is 5891. The wind is light cross-offshore, making it clean. But be warned, this is only for experts. The wave is going to be big and heavy, and the period is long enough to make it feel even bigger. The tide and wind are favorable, but the size is not for the faint of heart.
After that, we have a long gap of poor surf until Wednesday morning the 25th. That’s over a week of rubbish. The wind is light and cross-onshore, and the swell is 8ft from the SW with a 18-second period. The combined energy is 4682. It’s marginal, but it’s the best we’ve seen in a while. The wind is just slightly onshore, so it won’t be glassy, but it’s a potential go if you’re desperate.
So, to sum it up: the best early window is Thursday the 10th. After that, it’s pretty much a write-off for two weeks, with a tiny glimmer of hope on the 25th. The forecast is more reliable for the first few days, so get out there while 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.
