The Lowdown
Alright, lads, Rusty here. Gotta level with you – this forecast is a real head-scratcher. We’ve got one spot on the menu, Lefthanders, and it’s a classic reef that usually loves a solid WSW swell. But the problem isn’t a lack of waves; it’s that the ocean is absolutely puking with power. For the next week and a half, the swell is just too damn big for this place to be any fun for a paddle surfer.
The pattern is a relentless pulse of long-period groundswell from the west-southwest. The combined energy readings are eye-watering, regularly hitting four and five-digit numbers (like 4188, 10842, 16896) – that’s strong to very strong energy, a proper freight train of water. The water temp is about average for the time of year, so no surprises there.
Let’s run through it. The first real opportunity shows up on Thursday, July 16th, with a 10-foot swell from the WSW at 14 seconds, but the finder is shouting that it’s too big for the break. Same story Thursday afternoon, Friday, and Saturday – the swell hits 18 feet on Saturday, July 18th, with a 14-second period. That’s a massive, 30-foot-plus face wave. It’s a monster swell, but not for us; it’s going to be a washing machine, and the wind is howling onshore or straight onshore. The setup is more interesting for kite surfers than paddle surfers during that big blow.
The wait continues. Sunday and Monday, still too big. Massive energy (3314, 3169) and no let-up. We get a glimpse of hope on Tuesday, July 21st, with 10-foot from the SW and a nice light ESE cross-offshore breeze – that’s clean. But again, the swell size is just too much for the reef to handle safely or make good waves.
The real first standout is the morning of Friday, July 24th. The swell finally drops to a more manageable 7 feet from the SW at 13 seconds, with a light NE cross-offshore breeze keeping it clean. The combined energy is a moderate 1485. The finder calls it “excellent surf conditions for experienced surfers.” That’s the window. It’s still a bit of a lump for a beginner, but for anyone with a bit of experience, that’s the best session on offer. The glassy Friday afternoon with 6 feet is a close second.
After that, we get a bit of a chop from the wind on Saturday, and then a bunch of poor conditions until the very end of the run. The second standout comes much later, on Tuesday, July 28th. The morning session has a clean 5 feet from the SW at 14 seconds with a gentle offshore breeze from the east. That’s a beautiful, clean, long-period groundswell. The combined energy is a moderate 1483. This is a proper reef wave, and with offshore wind, it’ll be a dream for the experienced crew. The swell direction is a perfect match for the spot’s optimum, so expect some long, lined-up walls.
Be mindful that long-period swells like this (14-15 seconds) can sometimes make beach breaks close out too fast, but at a reef like Lefthanders, it’s pure gold. The crowds are listed as “often” here, so expect company for these good sessions.
The final few days of July show more swell, but it’s back to being too big. The 31st of July has a glassy 15-foot swell from the west with a 14-second period. That’s a massive, dangerous wave for the reef, strictly for the lunatics.
So, mark your calendar for the morning of Friday, July 24th, and the morning of Tuesday, July 28th. Those are your windows. The rest is a washout for paddle surfing, but a hell of a show for spectators.
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.
