The Lowdown
Imperial Version
Hey crew, Rusty back with the lowdown. We’ve got one spot on the menu, and it’s a full-on affair.
Alright, Lefthanders. It’s a reef break and it's very consistent, so you know it's gonna be busy. Exposed as anything, so it hoovers up all the energy. The water temp is pretty much what you’d expect for this time of year, nothing special.
We kick off on Monday, September 14th, and it’s all about the size. The swell is already a solid 12 ft from the SW with a 14-second period. The combined energy is cranking at 5483, but the report says it all: this is way too big for the break. Such a bummer because the morning winds are a clean cross-off from the ESE at 9 mph. This pattern sticks through Tuesday the 15th. The swell drops a bit to 10 ft, but it's still a monster with an energy of 4009. The morning has clean offshore winds from the E at 6 mph. It looks perfect, but it's still too much power for a beginner-friendly wave.
Things ease up a tad on Wednesday the 16th. The swell backs off to 7 ft, and the energy drops to 1380. The morning has clean cross-off winds from the NE at 13 mph. It’s in the "marginal" zone, though. Thursday the 17th is a total loss – messy onshore winds and junk.
Now, mark your calendars for Friday the 18th. Another big pulse hits: 10 ft of swell from the WSW with a 15-second period. The energy is back up at 4503. The morning wind is a strong cross-off from the NNE at 19 mph, and the note says "too big." The afternoon turns into a rainy, messy cross-off.
Saturday the 19th is a total washout with 13 ft of onshore slop and strong winds. Don’t even think about it. Sunday the 20th brings more of the same – another 12-13 ft swell, but the winds are cross-onshore and choppy. The energy is massive (7127), but it’s a washing machine.
There’s a pattern here. The waves are pumping, but it’s consistently too big for this break to handle cleanly. There are some glimmers, like the morning of Wednesday the 23rd, when 10 ft of SW swell meets a light cross-off SSE wind at 6 mph and a 15-second period. Clean again, but still too big. The energy at 4567 tells you it's packing a punch.
The standout, and I mean the one for the big dogs, is the morning of Saturday, September 26th. It’s a long way out, so keep your expectations in check, but the forecast is for a 15 ft SW groundswell with a massive 19-second period. The combined energy is a staggering 14648. The winds are a clean cross-off from the ESE at 13 mph. This is serious, heavy, big-wave territory. Only for the experts. For everyone else, grab the camera.
The week wraps up on Sunday the 27th with a still-big 10 ft SW swell and a 16-second period. The winds turn offshore from the E at 9 mph. It's clean, but it’s still a heavy wave.
So, what’s the verdict? The only real window for a regular paddle is maybe the morning of Wednesday the 16th when the swell drops to 7 ft, but it’s only rated marginal. Everything else is either too big, too messy, or both. This spot is an absolute unit. For most of the 16-day run, it’s a spectator sport.
Keep your head on a swivel.

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.
