The Lowdown
Alright, let’s get stuck into it.
The weekend is a no-go for any of us wanting to get a wave. The swell is just too damn big. We’re looking at 13ft of SW swell hitting Tuesday morning with 16-second periods. That’s a lot of water moving. There is plenty of energy too, with a reading of 8888. This is one for the experts only. The good news is the wind is clean, a cross-off ESE breeze at 12 mph. But still, unless you’re charging, it’s a day to watch from the shore.
Wednesday keeps the size up there, with 10ft of SW swell. The morning sees an ENE cross-off at 12 mph, and it cleans up for the afternoon with a true offshore from the ENE at just 6 mph. It’s still heavy and powerful, but the surface should be perfect. Too big for the average punter, but for the guys on the big guns, there could be some serious gems.
Thursday is where it starts to become interesting. It’s still a solid 7ft on the morning, but the energy drops right down to a weak-ish 1920. The wind is a cross-off from the NE at 12 mph so it should be clean, but the tide and the surf itself look a bit ordinary. It’s a score of 3 out of 10, so not really worth the paddle. However, the afternoon is a different story. The wind swings around to the north and drops right out, becoming glassy. The swell holds at 7ft from the WSW with a slightly longer 15-second period. The energy reading of 2109 is still moderate, but with the glassy conditions, it’s an excellent window for the experienced surfers. This is a standout.
Friday morning is grumpy. Cloudy, a cross-off breeze from the NNE at 12 mph, and 7ft of WSW swell. It’s a 4 out of 10, a marginal surf forecast. The afternoon sees the wind clock around and get messy, a cross-shore from the N at 12 mph, puffing up the 10ft swell. The period has jumped to 18 seconds, and the energy is up to 5167, but that wind is killing it. The scores are high, but it’s going to be a battle.
Saturday, you’re better off sleeping in. The morning brings a solid 10ft WSW swell but it’s onshore from the west at 12 mph. That’s just messy. The afternoon isn’t much better with a cross-onshore breeze and the size dropping a little to 8ft. It’s a 2 out of 10. Leave it.
Sunday takes a proper turn for the worst. The wind is howling onshore from the WNW, hitting 18 mph in the morning. There’s 10ft of swell but it’s absolutely blown out. Zero score. The afternoon is even bigger at 12ft, with a strong cross-onshore. Kite surfing looks like more fun than paddling out into this.
Monday brings a massive opportunity though. The wind is dead, glassy from the north at only 3 mph in the morning. There is 12ft of SW groundswell rolling through with a 14-second period. The energy reading is high at 4916. It’s still way too big for beginners, but that clean face on 12ft of swell with no wind? That’s a session for the brave. The afternoon’s wind swings around and gets messy, so make the most of the morning.
Tuesday morning sees another glassy window with 10ft of SW swell and a 15-second period. The energy is still strong at 4394. The forecast says wind and tide are favorable but it’s over the 8ft mark, so again, experts only. Afternoon is a write-off with a cross-shore breeze.
Wednesday is a bit more manageable. The swell drops to a still-chunky 8ft, but it’s dropping. The morning wind is a gentle cross-shore from the south at 9 mph. It’s a 2 out of 10, so pretty ordinary. The afternoon is a bit cleaner with a cross-off from the south at 18 mph, keeping it a bit more together.
After that, the week is a mixed bag of average conditions until it kicks back in the following week. We’re looking at a couple of days of onshores and poor surf before another pulse arrives. Around the 21st and 22nd, we’re looking at a huge swell, 16ft to 18ft, but with onshore and cross-onshore winds. That’s another one for the chargers to talk about, but for most of us, it’s a miss.
So, in summary, the standout windows are Thursday afternoon when the glassy conditions hit the 7ft swell, and Monday morning when the 12ft swell is clean and big. Both are for experienced surfers only, but they are the best of a pretty wild forecast.
Rusty out.

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.
