The Lowdown
Alright folks, Rusty here with a look at what’s on the cards. We’ve got a solid run of massive south-west swell lining up, but there's a catch – it's huge. This ain't a week for the faint-hearted; this is expert territory, big-time.
The first real action we can talk about kicks off Wednesday afternoon, the 2nd of August. Lefthanders is pumping with 12ft of SW swell, and there's a whopping combined energy of 4332 (moderate wave energy) in the water. The wind is cross, and the forecast says wind and tide are favourable – which is great. But make no mistake, this swell right now is already too big for this break for a beginner. Water temp is sitting at 66°, which is a touch warmer than normal for this time of year.
Thursday the 3rd sees the swell bump up further to 13ft from the SW in the morning with a very long 15-second period, but the NW wind at 19 mph is cross-on and ruining it. By the afternoon, it's still messy with strong onshore winds. We have to wait for a window. Friday the 4th looks big – 16ft to 18ft of WSW swell, and the afternoon has gentle cross-onshore winds, but again, it's just too big for anyone but experts. The combined energy pushes into the four digits, hitting 12490 (very strong wave energy) on Friday afternoon. This is a serious amount of water moving around.
There's a potential standout stretch from Monday the 7th through Wednesday the 9th. Swell sizes drop a touch to around 10ft to 13ft from the SW, but the wind turns lighter and offshore or cross-offshore. Monday morning we've got light SSW airs at 6 mph, giving a clean cross-shore vibe. Tuesday the 8th looks even better with clean ESE light breeze, and Wednesday the 9th still clean with a moderate NE breeze. Even though the wave comment keeps saying it's too big for the break, for a crew on big-wave gear this is your window. The wind is right, the swell is solid with long, 15 to 16 second periods, and the energy is all there.
Then things get a bit messier again from the 10th onwards with onshore winds and lumpy conditions. The standout option for a true big-wave session in clean conditions is definitely Tuesday the 8th of September. That morning at Lefthanders, you’ll find 13ft of SW swell with a 16-second period, light ESE winds making it clean, and combined energy at 8429 (strong wave energy). This is the pick of the bunch.
Another big pulse shows up towards the 15th of September, with a monster 26ft of WSW swell coming in on Tuesday, the 15th. Periods are 14-15 seconds, and the combined energy is astronomical – 27986 (very strong wave energy). The wind is light and onshore-ish, but this is a colossal, expert-only proposition that is weeks away. Keep an eye on it, but don't plan your life around it yet.
So, to wrap it up: there's no safe, small-wave fun in this outlook. It's all for the big-wave chargers. The standout clean days are Monday the 7th through Wednesday the 9th, with Tuesday the 8th being the absolute sweet spot for a session on proper gear.
Stay safe out there and respect the ocean.
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.
