The Lowdown
Alright, surfers, Rusty here. Let’s get into the long-range look for Lefthanders.
We’ve got a solid run of surf on the cards, but the story is mostly about *too much* of a good thing. The water temp is sitting at 65°, which is about a degree and a half warmer than usual for this time of year – nothing drastic, just a touch of summer still hanging around.
The first swells we see are pumping in from a solid WSW direction, but the problem is size. For the first week and a half, the swell is just too big for this spot. The energy is huge, ranging from 3,361 to over 13,000 (moderate to very strong), meaning the waves are packed with power. But with heights consistently over 8 ft, this is strictly for the experts, and even then, the conditions are often messy with cross-onshore winds. The first ten days are a washout for the average surfer – big, choppy, and blown out. There’s a lot of time where it’s just not worth paddling out.
The real standout window opens up much later, and you’ll want to wait for it. The best bet is Tuesday, September 15th in the morning. That’s the one true gem. The swell drops to a more manageable 8 ft from the SW, with a period of 13 seconds – that’s a solid groundswell with good shape. But the kicker is the wind: a light offshore breeze from the east. That’s glassy, clean conditions. The energy is still moderate (2,438), so there’s plenty of push. The wave comment says it’s excellent for experienced surfers, and for a spot like Lefthanders that is very consistent, this is the day to circle. Just be aware, with a rating like that, crowds are often possible here.
Before that, on Wednesday, September 9th, the wind turns clean with a cross-offshore breeze, but the swell is still a bit too big at 10 ft. It’s clean, but still a big wave day for experts only.
A few days later, on Friday, September 11th, the swell drops to 8-8 ft, but the wind is onshore or cross-shore, making it a marginal call. Not the best.
For the second week, the pattern is similar: big swell and tricky winds until the 15th. After that, the 16th sees a return to big, lumpy conditions. So, the long-range call is clear: hold out for the morning of the 15th. That’s your window.

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.
