The Lowdown

G’day, Rusty here. Let’s break down the next couple of weeks at Lefthanders. This is a reef set-up, real exposed to west and southwest swells, but the first batch of days is a rough one. Too much energy in the water and the wind hasn’t got its act together, so it’s messy.

We start on Thursday, September 3rd with a big SW groundswell running 4.0m, period around 15 seconds—definitely a groundswell. Problem is, the wind is a moderate cross-onshore, and it’s just poor out there. The combined energy is 6562, so there’s a heap of power. That trend holds through Friday the 4th, with swell hitting 5.0m in the morning and 4.5m in the afternoon. The afternoon lightens up a bit with a gentle breeze, but the swell is still too big for the break. The energy reading Friday afternoon goes to 10411—that’s a serious amount of water moving. Not for the faint of heart.

Saturday the 5th stays lumpy with fresh cross-onshore winds and 4–4.0m swell. Sunday the 6th brings a brighter note: a clean, cross-offshore SSE breeze at 19 mph, and a 4.0m SW swell with a 13-second period. But again, the comment says it’s too big. Energy is 6282. That clean wind pattern sticks around for Monday the 7th and Tuesday the 8th, with offshore and cross-offshore flows, light winds—gorgeous conditions. But the swell size is still 4–4.0m, and the periods jump to 16–18 seconds. That’s very long-period groundswell, perfect for a reef, but at that size it’s big and heavy. The energy on Tuesday afternoon is 10815. Only the experienced ones should be suiting up.

Wednesday the 9th stays clean with swell easing to 3.0m and a 15-second period, energy at 4565. Still big, but slowly dropping. Thursday the 10th sees the swell finally come down to 2.3m from the SW, period 14 seconds, but the wind turns cross-shore and the wave comment calls it marginal. Energy is 2335—moderate. It’s not a standout, but it’s close to being okay.

Friday the 11th gets messy again with moderate cross-onshore winds and a 2.5m swell. Then Saturday the 12th throws another massive spike: 5.0m swell with a 16-second period, energy hits 11914—the highest all forecast. Onshore and choppy. No chance. Sunday the 13th and Monday the 14th still show 4–4.5m with cross-onshore winds, still too big and not clean.

The real gem shows up on Wednesday afternoon, September 16th. Swell finally drops to 2.1m from the SW, period 13 seconds, and the wind goes light and cross-offshore from the NNE at 6 mph. Clean as a whistle, the comment says excellent for experienced surfers, and the combined energy is 2993—solid and fun. That’s the session to aim for.

Tuesday morning, September 15th also looks clean with a 3.0m SW swell and cross-offshore wind, energy at 3431. A little bigger, but still clean. The tail end, Thursday the 17th and Friday the 18th, shows swell dropping to 1–1.7m, but with fresh winds and only marginal conditions.

So the pick of the fortnight is Wednesday afternoon, September 16th, with Tuesday morning the 15th as a backup. Don’t even think about paddling out on those 5.0m days unless you’re on a big-wave rig.

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.
