The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Lefthanders.
We’ve got a stretch ahead that’s really gonna test your patience if you’re a beginner. The water is sitting at 65° right now, which is a touch warmer than normal for this time of year, so that’s a small comfort. But the story here is size. The swell is just too big for most of the next two weeks, and the wind is often messy.
The first real chance to get in the water that’s worth talking about is Thursday, the 10th of September. The morning is still a bit hefty at 7ft from the SW, but it’s the afternoon that’s the standout. The wind goes dead calm, glassy, and the swell is a clean 7ft from the WSW. The energy is moderate (2109), and the period is a solid 15 seconds, giving it that groundswell push. This is your window if you’re experienced. That 7ft on a reef with offshore/glass conditions? That’s the quality window. Be aware that crowds are likely here, but for this kind of quality, you’ll take it.
For the rest of the first week, it’s a battle. The swell is consistently over 8ft, often 10ft to 13ft, which is expert territory only. The wind is a problem, too. From Saturday the 12th right through to the end of the outlook, we see strong onshore winds and rain showers. The wave energy is strong (often in the 4000s to 13000s), but the quality is blown out. It’s a messy, powerful ocean.
The second week is basically a write-off for a good surf. There’s a small window on Monday the 14th with glassy conditions in the afternoon and an 12ft WSW swell, but that’s still too big for most. The rest of the week is onshore and lumpy. For the 21st and 22nd, the wind is near gale-force, and the swell is over 13ft. That’s not surfing, that’s survival.
So, the honest truth? If you’re an expert, nail Thursday afternoon the 10th. That’s the cleanest, most manageable window. For everyone else, this is a long, blank run of poor conditions. It’s a rare spot to have this much swell on offer, but the quality just isn’t there for the vast majority of the forecast.
Stay safe, and don’t be a hero when the wind is howling.
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.
