The Lowdown
G’day, Rusty here, and I’ve got a look at what’s cookin’ for Lancelin over the next couple of weeks. Let’s be real – the first few days are a bit of a write-off, but there’s some proper gold further down the line if you’ve got the patience.
The start of the period is a rough one. We’ve got a solid pulse of swell from Wednesday the 2nd, with waves around 8 ft to 8 ft, but the wind is cross-on and messy, making it choppy and pretty average. Thursday the 3rd and Friday the 4th get even bigger – 10 ft to 12 ft – but with onshore and cross-on winds hitting 15 mph, it’s blown out. The combined energy is pumping hard (over 3500 to 5181), but it’s all wind-affected junk. Not worth paddling out.
Saturday the 5th is a write-off too – strong, lumpy cross-on wind and even a risk of a thunderstorm. This is a stretch of four or five days where you’re better off doing something else.
Then, things start to turn. By Sunday the 6th, the wind swings offshore and cross-off, and the water cleans up. Swell is still big – 12 ft to 13 ft – but with a 13-second period, it’s got some push. The wind is still strong (19–28 mph), so it’s more of a kite-surfing setup than a paddle-surfing one. The combined energy is massive (over 5300 to 5735), so if you’re a strong charger, you’ll find something, but it’s not the highlight.
Now, here’s the standout. Tuesday the 8th of September. The morning has a clean 10 ft swell from the WSW with a 15-second period, and light offshore winds from the east at 15 mph. The energy is solid (3901). But the afternoon is where it’s at – 10 ft, 17-second period, and clean, moderate offshore wind from the ESE. That’s prime Lancelin reef territory. The wave quality is excellent for experienced surfers. This is the best call of the whole window. The water’s around 65°, which is about average for this time of year, so no surprises there.
Wednesday the 9th is still decent – 8 ft to 7 ft, with a gentle offshore breeze in the afternoon, clean faces. The energy drops a bit (2010 to 2324), but it’s a solid follow-up.
There’s a bit of a lull in the middle of the second week, with smaller, cross-shore wind on the 10th and 11th, but the long-period groundswell on Friday the 11th morning is interesting – 5 ft but with a 19-second period and light cross-off wind. That’s a sneaky good session if you know where to sit on the reef.
The next real standout pops up on Saturday the 12th of September. Morning session: 8 ft, 16-second period, light offshore wind from the ESE. The combined energy is 3745, and it’s excellent for experienced surfers. Clean, lined up, and the reef will be doing its thing. The afternoon is a bit more crossed up, but still worth a look.
After that, the swell holds around 7 ft to 8 ft through to the 14th and 15th, but the wind gets a bit more southerly and cross-off, keeping it clean but not as glassy. Then we get another cracker on Wednesday the 16th of September: 6 ft with a 19-second period, light cross-off wind, and combined energy of 3486. That’s a long, clean groundswell that will wrap beautifully into the reef. The afternoon gets a bit bigger (10 ft) but cross-shore, so morning is the call.
The last few days of the window on the 17th are average – cross-shore wind and 8 ft to 7 ft swell – not the best, but you could still get a wave.
If I’m picking the absolute best, it’s Tuesday the 8th of September afternoon and Saturday the 12th of September morning. The 8th has the bigger, longer-period swell with offshore wind – that’s as good as it gets. The 12th is a close second. The 16th morning is a sneaky third. For the rest, you’re either fighting the wind or the size.
Rusty out.

Information about the Lancelin Surf forecast
The above surf forecast table for Lancelin provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lancelin can be found by selecting the local surf guide option on the grey menu. Our Lancelin 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 (Lancelin) 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 Lancelin 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.
