The Lowdown
Alright, Rusty here, checking in on the options for the next couple of weeks. It’s a heavy stretch ahead, no doubt about it.
The whole forecast period is dominated by one spot: Lefthanders. This is a very consistent reef break, exposed to the swell, but it’s not for the faint of heart. Right from the start, the ocean is fired up and angry. Thursday the 6th kicks off with a massive 13ft WSW groundswell, with a very long period of 16 seconds, and a combined wave energy of 8707. That’s a lot of power, but it’s blown out with 22 mph cross-on winds. The water is sitting at 68°, which is 4° warmer than normal – that’s notably warm for this time of year. The conditions are just plain poor for surfing.
This pattern of huge, powerful swell and dirty wind sticks around for days. Friday the 7th, Saturday the 8th brings a 23ft monster, and it stays over 13ft for days on end. The wind is a problem almost every day, often onshore or cross-onshore and strong. From the 6th right through to the 13th, the only call is "poor surf conditions" or the swell is "too big for this break." The entire first week is a wipeout for any sort of quality session.
The first real glimmer of hope arrives on Friday, August 14th. The morning shows a 15ft SW groundswell with a 16-second period – still a big, long-period groundswell. But the wind drops and goes cross-offshore from the NNE at just 6 mph. The comment reads "clean." That’s the standout for the whole outlook. The power is intense (combined energy of 9402), but for an expert surfer on a reef, this could be magic. Crowds are often here, and on a Friday with that much size and clean conditions, expect a few boats and a crew out. It's still huge, so this is for experienced chargers only.
After that, things get tricky again. Saturday the 15th starts clean with a 10ft swell, but the wind rips up quickly. Then from the 16th onward, it’s back to lumpy, onshore junk for the most part. There are a couple of late, promising moments, like Thursday the 20th afternoon, where the swell drops to 15ft from the WSW with a 15-second period and the wind goes *glassy* with a combined energy of 11031. That’s a serious session in waiting, but it's nearly two weeks away and a lot can change. The following Friday the 21st also looks clean again with cross-off winds and a 13-15ft SW swell. These are the late highlights, but the long-range calls have that "wait and see" feeling to them.
For a beginner, the entire 16-day window is a no-go. Everything is over 5ft, and for most of it, over 8ft, making it expert territory only. The consistent size and power, combined with very long periods, mean this is a reef and point break show—not a beach break for learners.
So, to sum it up: one really good window on Friday the 14th morning if you’re an expert, and a couple of potential late clean-ups around the 20th and 21st. The rest of the time it’s big and messy.

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.
