The Lowdown
Alright, listen up, let's talk surf for Lefthanders.
The water temp feels about normal for this time of year, nothing crazy. The one window for action, and I mean the only real window, is starting Monday, September 14th. The swell direction is from the SW, which is perfect for this reef. The wave energy is strong, hitting 4000 to 5000 (moderate to strong combined energy). But there's a huge catch: the swell is predicted to be just too big for this break. We're talking 10ft to 13ft of WSW to SW groundswell with a very long period of 14 seconds. This is a big, powerful wave. For a spot like Lefthanders that sees a lot of swell, this is pushing it into expert-only territory. The wind on Monday morning is a light SE breeze, coming cross-offshore, which will keep the waves clean. This is the best bet of the whole outlook, but only if you've got the skills and the nerve.
Tuesday, September 15th, is similar. Still a massive 10ft SW groundswell at 14 seconds. The morning looks best with a glassy light offshore ENE breeze at 6 mph making for super clean conditions. Again, it's on the "too big" side. Afternoon turns a bit onshore, but clean lines should still be there.
Mid-week drops off. Wednesday the 16th sees the swell drop to 7ft, but the wind gets messy. Thursday the 17th is a washout with poor conditions and strong wind.
Then we get a wild card on Friday, September 18th. A fresh 10ft swell, long period 15 seconds, and a clean, strong cross-offshore wind from the SSE at 25 mph. The energy is big (4166), but that wind is punchy. It might clean it up, but that's a gale blowing. It's again too big. The rest of that weekend and into the next week is a repeat performance: massive swell, consistently 10ft to 15ft, with very long periods, but with cross-shore or onshore winds messing up the surface. The energy gets massive (over 10,000 on some days), but conditions at Lefthanders just aren't lining up for good surf.
Honestly, for this 16-day stretch, unless you are a seasoned charger, you might be better off watching this one. The swell is just too big and the winds are not in our favor. It's a real shame because the swell direction is perfect.

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.
