The Lowdown

Right. Rusty here. Let's talk about what’s coming down the line for Lefthanders. This is a reef break that’s very consistent, wide open to the swell, and best when that energy comes from the west-southwest. But I’ll be straight with you—this whole 16-day window is a weird one for this spot. The swell is pumping, absolutely huge, but for a beginner-friendly reef like this, it’s just too much. The water temp is about average for the time of year, so no surprises there.

The outlook starts on Tuesday, 11 August, with a massive 20ft SW swell carrying some serious grunt—combined energy is 17353 (very strong). But it’s blowing 19 mph cross-onshore, making it lumpy, and frankly, that wave height is only for the hardcore or the insane. It’s too big for this break for most of us.

Wednesday the 12th and Thursday the 13th see the swell ease a bit, still 13ft to 15ft SW, with long periods around 15–17 seconds. Energy is still well up there (8696 to 10444). Thursday morning looks tempting with only 3 mph cross-shore wind and nearly glassy conditions, but the size is still a problem. It’s clean but overhead-plus for days.

Friday the 14th morning shows a drop to 12ft SW, with 9 mph cross-offshore wind and the flag saying clean. The combined energy is 6227 (moderate to strong). This is a standout moment for experienced surfers only. The swell direction (SW) lines up well with Lefthanders’ optimum (WSW). It’s still big, over 8ft, so this is expert territory only, but the conditions are as good as they’ll get.

Saturday the 15th morning holds 10ft SW with 12 mph cross-offshore and a clean face, but it’s still too big for this beginner reef. The afternoon drops to 8ft, but the wind goes cross-shore with a chop—marginal at best.

Sunday the 16th and Monday the 17th are a washout: Sunday has 12ft SW and clean offshore winds, but still too big. Monday the 17th brings rain and howling 25 mph onshore wind, with 15ft WSW swell—total mess.

From Tuesday the 18th onward, the trend continues: big swell (10ft to 21ft), long periods, and mostly messy cross-onshore wind or, on the 19th, strong 25 mph cross-offshore that’s technically “clean” but for a 20ft swell? Only the bravest. The energy readings stay in the strong to very strong range (3625 to 18316).

There’s really only one session that stands out for quality: Friday 14 August morning. A 12ft SW swell, clean cross-offshore breeze from the NNE, and the reef will be handling the energy beautifully. But it’s a true big-wave session—only for experts. Crowds are often here, but on a day like this, you’ll have it to yourselves.

Everything else in this 16-day run is either too big, too windy, or both. If you’re a beginner or intermediate, take a break. For the pros, that Friday morning window is your best bet.

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.
