The Lowdown
Alright, let’s get into it.
Okay, so the next couple of weeks at Lefthanders are going to be a story of too much of a good thing for most of it. We’ve got a solid, consistent run of south-west groundswell that’s just pouring in, but the size on the face of it is the big problem. We’re not talking about a playful wave here; this break is going to be absolutely pumping with energy, but that also means it’s going to be a washing machine for a lot of the period. Hold onto your board.
The first real window is this Friday afternoon, the 11th. The forecast shows a solid 9.8ft of WSW swell, with a long 18-second period pushing a heap of energy in here – we're looking at a combined energy of 4988. That’s a lot of water moving. The problem is, the wind is a moderate cross-shore from the NNW at 25 km/h, which is gonna put a bit of a chop on it. The call is that it’s just too big for this break to handle properly, which is a shame because the tide and swell direction are otherwise favorable. The water’s sitting at 64.6°, which is a touch warmer than what’s normal for this time of year, so that’s a little bonus if you’re just getting a look at it.
Then, the weekend and into Monday the 14th is a write-off. The swell is up to 11.5ft on Saturday and Sunday, but the wind is blowing right onshore from the west. It’s going to be a messy, stormy mess. If you were thinking of paddling out, forget it. Saturday morning has 7.2ft on the face but that onshore wind kills it. It’s not going to be pretty.
Now, Monday the 14th is where things get interesting, but it’s a double-edged sword. The swell drops a touch to 13.1ft from the SW, but the wind swings around and goes light cross-offshore from the ESE on Monday afternoon. Clean, glassy faces, and the energy is still strong at 5796. Sounds perfect, right? Problem is, 13.1ft at this reef is expert-only territory. It’s still flagged as too big for the break. You’d need to be a local charger who knows the place blind to even think about it.
The standout of the whole run, honestly, is Tuesday the 15th. The swell drops back to a still-considerable 9.8ft from the SW with that long 14-second period. The energy is still strong at 3420. But the magic is the wind. Tuesday morning is a clean offshore ENE breeze at 15 km/h, and Tuesday afternoon… oh boy. It goes glass. We’re talking 5 km/h southerly wind, absolutely no wind, on a 9.8ft SW groundswell. That’s about as good as this place gets when it’s this big. The size will still be pushing it for the average surfer, but for the experienced crew, this is the one to circle. This is clean, powerful, and the best conditions we’re going to see for a week.
After that, from the 16th through the 18th, things start to ease down. The swell drops to around 4.6ft to 8.2ft, but the winds turn messy and cross-shore, and the quality just isn't there. It’s a bit of a lull in the quality. There are waves, but the conditions are pretty average, and the energy has dropped off.
We’re going to see another big pulse kick in for the weekend of the 19th and 20th, but it’s not great. The swell rockets up to 16.4ft on Saturday the 19th, with strong winds and a messy cross-chop. Not a good look. That morning is a complete mess. Saturday afternoon is a bit cleaner with a cross-offshore S wind, but it’s still a massive 14.8ft wave with a strong energy reading of 7169 – again, way too big, and the wind will be fresh. We’re back to the same story: lots of water, not a lot of shape.
From the 21st to the 23rd, that swell stays stubbornly big, around 13.1ft to 14.8ft, and the wind keeps blowing from the west and onshore. It’s just going to be pounding and messy. Not a day for the faint of heart, and honestly, not a day for anyone unless you’re chasing a tow-in. The energy readings up to 9231 on Monday the 21st show you just how much water is moving around.
The long-range crystal ball is a bit murky for the final few days. The 24th sees a drop in size to a more manageable 5.6ft, but the wind is on it. Then it starts to fire up again on the 25th and

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.
