The Lowdown
Alright, Rusty here, let's get stuck into things. The forecast is showing a classic pattern of a long wait for the good stuff. The first few days are a write-off for the kind of waves we want, so we're looking at a big gap until the real action kicks in.
The first real chance for a paddle won't come until Tuesday morning, August 4th. Lefthanders is going to be absolutely cooking with a solid 12ft swell out of the WSW, but that's a problem. The combined wave energy is a massive 7486, and this one is for the big dogs only. The wind is straight onshore, keeping it clean, but it's just too much juice for the average surfer. This is a day for the experienced crew, and even then, you'll be working hard.
The rest of the first week, from Wednesday August 5th through to Sunday August 11th, is a no-go. The swell is consistently huge, over 13ft and hitting 20ft on the Saturday, with energy readings pushing well into five digits. The wind is all over the place, mostly cross-onshore or onshore, and the break is just too exposed. It's going to be a churning, messy beast. Leave it for the kits and the tow-in guys.
After that onslaught, things start to settle down. The swell drops back to a more manageable 12ft on Thursday August 13th, but it's still a bit too big and the wind isn't great. The real standout is the following morning.
Friday, August 14th is where it's at. The early morning session at Lefthanders is the pick of the entire forecast. The swell has dropped to a more human 7ft from the SW, and the energy is a moderate 2410. But the real magic is the wind – it's glassy, with a light offshore from the ENE. The water is sitting at 67°, which is a touch warmer than normal for this time of year, so a spring suit should be fine. This is the one to circle on the calendar. The reef will be working perfectly, offering some long, clean lines. It'll be a bit crowded, as it often is when it's good, but for a wave like that, it's worth it.
The following weekend, Saturday 15th and Sunday 16th, the swell ticks back up to 10ft. That's still big, but the wind on Sunday morning is a clean cross-off from the NNE. If you're an expert, it's worth a look, but for most of us, the Friday morning window is the only real game in town.
The final few days of the outlook, Monday 17th and Tuesday 18th, see the swell staying around 8ft to 10ft, but the wind gets messy again. It's not a write-off, but it's not the same quality as that Friday morning glass-off.
So, to sum it up: there's a lot of swell, but most of it is too big and poorly timed. The true standout is the glassy, clean Friday morning the 14th. If you're an experienced surfer, the Tuesday morning the 4th might tempt you, but it's a beast. For everyone else, wait for the 14th. That's the one.
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.
