The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next 16 days for Lefthanders.

First thing you gotta know: we’ve got a run of pretty rough conditions to start with. The first few days are a write-off—wind and swell are just not playing nice. The first real chance for a surf doesn’t come until Sunday, September 20th, and even that’s marginal. So there’s a gap of about 4 days with no real recommendation.

Sunday, September 20th rolls around and we finally see some improvement. The morning is showing a 8ft swell from the WSW with a nice 12-second period, and a gentle SSW breeze keeping it cross-shore. Combined wave energy is moderate at 1496. Not a standout, but it’s the first passable surf. The afternoon actually looks a bit better—8ft from the SW, same clean wind, and slightly more energy at 1959. It’s still marginal, but for a Sunday session it’ll be okay. Crowds are often here, so expect company.

Now, here’s where things get interesting. The real standout is the Monday, September 21st morning session. We’re looking at a solid 12ft swell from the SW with a 14-second period. That’s a proper groundswell. The wind is light and onshore from the WSW at 6 mph, so it’s glassy and clean. The combined energy is strong at 4436. But—here’s the catch—the swell is predicted to be too big for this break. For a beginner-friendly reef break like Lefthanders, 12ft is pushing it. This is expert territory. Still, if you’ve got the skills, the quality is high. Just know the crowds will be there.

Tuesday, September 22nd is a bit more manageable. The morning has a 8ft SW swell with a clean cross-off wind from the S at 12 mph. Energy is strong at 2630. The afternoon sees the swell bump to 10ft with a cross-off breeze from the S at 16 mph, energy hitting 4024. Again, this is getting big for the break. Not for beginners.

After that, the swell stays solid but the quality drops off. Wednesday, September 23rd has 8ft SW swell but the wind is light cross-onshore, so it’s a bit bumpy. Thursday, September 24th is similar—7ft to 8ft with moderate cross-shore wind. Not bad, but not top-tier.

Then we get to Friday, September 25th—watch out. Massive 16ft swell coming from the WSW with a 19-second period. That’s very long period groundswell, and the energy is huge at 17059. This is for experts only, and even then, it might be too much. The wind is light cross-onshore, so it won’t be completely blown out, but it’s a serious wall of water.

The really big stuff continues through the weekend. Saturday, September 26th has 20ft swell from the SW with 16-second period and fresh cross-onshore wind. This is extreme. The Sunday after is still 12ft from the SW with moderate cross-shore wind—again, too big for most.

The final few days of the outlook, around September 28th to October 1st, we see the swell dropping back to 6ft to 13ft range. The best of this final stretch is Thursday, October 1st morning—8ft from the SW with a clean cross-off wind from the SE at 16 mph. Energy is moderate at 2801. That could be a decent session if the wind holds.

Overall, the standout is Monday, September 21st morning if you’re an expert and don’t mind a big, clean swell. For the average surfer, the best bet is Sunday, September 20th afternoon—smaller, cleaner, and more manageable.

Water temperature is not provided in the data, so I can’t tell you if it’s warmer or cooler than usual.

Keep an eye on the wind forecasts—when the wind stays light and cross-off, Lefthanders can be magic. But when it’s big and blown out, it’s just a washing machine.

This is Rusty, signing off.

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.
