The Lowdown
Alright, surfers, Rusty here. Let’s have a look at the long-range picture for Lefthanders. It’s a solid run of swell on the cards, but we’ve got a bit of a waiting game on our hands to get the good ones. The first couple of days are just too big for this spot, but don’t write it off – there are some proper standouts coming.
The window kicks off on Friday the 14th with a solid 12ft SW groundswell, but it’s just too much juice for Lefthanders. You’d be eating it on the takeoff. Water temp is 66°, which is a touch warmer than normal for this time of year, so the boardshorts are fine. It’s not until Sunday morning the 16th that things start to get interesting. We’ve still got a solid 10ft WSW swell, but the wind is a fresh cross-offshore from the NNE. That’s going to keep the face clean and the reef line-up manageable. This is when you want to be on it – early. Sunday afternoon is still 10ft but the cross-shore breeze will have it a bit lumpy. Monday the 17th is a write-off with a near gale blowing straight onshore and the swell jumping to 16ft – that’s a full-on hold-down session, not a surf.
The whole of next week is a no-go. The swell stays oversized, in the 13-16ft range, and the wind is mostly onshore or cross-onshore. It’s going to be a messy, dangerous week with a lot of water moving. We’re looking at a gap of nearly ten days before things settle down. There’s a hint of light winds on Tuesday the 26th with a 10ft SW groundswell and early morning glass. Could be fun, but it’s a long way out.
But the real standout is Saturday the 22nd. The morning looks magic. A clean 12ft SW groundswell with a light cross-offshore breeze from the NNE. That’s the one to circle. The swell direction is bang on the optimum for this break. It’s a bit big for beginners, so leave it to the crew who know the reef. Consistency is very consistent, and the long-period swell – 16 seconds – will have real power and push, with long waits between sets making the paddle out a bit easier. Crowds are often around, but for this kind of quality, it’ll be worth sharing it with a few mates. The energy reading is strong at 5678, so there’s plenty of push.
The following week has a few more promising windows. Sunday the 23rd looks okay for the morning with a fresh cross-off breeze, but the onshore kicks in later. Then the 26th morning’s glassy conditions look like another good shout, but by this point we’re in promising territory, not guarantees. Keep an eye on the forecasts. The period is still long, but the size is a bit more manageable at 10ft. The last few days of the window have some decent size but the wind is mostly cross-on, so it’s a bit of a fight.
So, overall, we’ve got one clear standout – that Saturday the 22nd morning session – and a couple of scattered opportunities if you’re willing to pick your moments. The first two days are too big, and there’s a big lull of poor conditions in the middle. Get on that Saturday early.
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.
