The Lowdown
Alright, let’s break it down. We’re looking at Lefthanders, a super consistent reef break that’s wide open to a WSW swell. The water’s about average for this time of year, nothing weird.
The first few days are a total wash. Monday morning looks clean with a 6ft SW swell and a 15-second period, cross-off breeze from the NNE at 12 mph, but the call is marginal. The rest of Monday and all of Tuesday are garbage—onshore winds, poor conditions, forget it. From Wednesday the 5th through the 16th, the swell is just too big for this spot. We’re talking 13ft to 26ft of SW/WSW groundswell, very long period, and the energy is huge (8697 to 44744). That’s expert-only, and even then the wind is often cross-on or onshore, so it’s not clean. The morning of Saturday the 16th is the first hint of something smaller—a 10ft SW swell, 14-second period, light S wind at 3 mph, but still too big for the break.
Now, the second week from Monday the 11th onward is a whole different story. The wind shifts to cross-off (ESE, SE, SSE) and the skies clear. The swell is still huge (16ft to 26ft) and long period (14-19 seconds), but the conditions are clean. The energy is strong to very strong (10610 to 44744). This is a big groundswell event, and at a reef, that long period is going to wrap in perfect. The standout is Friday the 14th morning: a 26ft SW swell at 19 seconds (very long period), ESE wind at 12 mph cross-off, and a combined energy of 44744. That’s a massive day for experts only. For anyone who can handle it, it’s a dream. The 15th morning is also a gem with an 18ft SW swell, light ESE wind at 6 mph, and clean conditions. The 16th morning is the first day the swell drops to 10ft, light S wind, but still too big for the break. The 17th and 18th mornings also look clean with 13-16ft WSW swell and good cross-off wind.
So, the first week is a dud unless you’re a hardcore expert looking for a wild, oversized groundswell. The second week, from the 11th, is a pure, clean, very long period groundswell event. The 14th is the absolute best—biggest, cleanest, and most powerful. If you’re an expert, that’s your day. The 15th morning is also pristine. The 16th morning is the first chance for slightly smaller waves, but still big. Crowds are “often” here, so with this quality, expect a packed lineup.

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.
