The Lowdown
G’day, I’m Rusty. Let’s break down what’s headed our way for Lancelin over the next 16 days.
We’ve got a solid stretch of swell coming through, but the wind is going to be the main character most of the time. The water temp is sitting at 66°, which is pretty much bang on average for this time of year, so nothing unusual there.
The real standout window starts Saturday morning, 29 August. That morning we’ve got a 4 ft swell from the WSW with a very long period of 19 seconds – that’s serious groundswell energy (combined energy: 1335). The wind is offshore out of the ESE at 16 mph, cleaning things up nicely. This is a reef break, so that long period will line up and give some proper shape. It’s a touch on the small side, but the conditions are excellent for experienced surfers. For a bigger bite, Sunday morning, 30 August, pumps in a 10 ft swell from the WSW with 18-second period and a light breeze from the NE at 6 mph. That’s a solid, powerful wave (combined energy: 5328) – but at 10 ft, it’s only for the experts. Both these mornings are the pick of the fortnight.
The first week has a lot of messy or marginal stuff in between. Thursday 27 August and Friday 28 August both have solid 7 ft to 12 ft SW swells, but the wind is a stiff cross-off at 19–25 mph, making it lumpy and hard work. Monday 31 August turns onshore with a 8 ft WSW swell and 12 mph wind – poor conditions. Tuesday 1 September through to Thursday 3 September sees onshore or cross-on winds again, with swell hanging around 7 ft to 10 ft, but the quality is low.
After a windy and choppy patch on Friday 4 September, Saturday morning 5 September shapes up okay again: a 7 ft WSW swell with 14-second period, light SE breeze at 6 mph, cross-off, and clean (combined energy: 2238). That’s a decent intermediate option.
The next standout is Monday morning, 7 September. A 8 ft SW swell with 16-second period, light SE breeze at 9 mph, cross-off, and clean. Combined energy of 3402. That’s a big, clean wave for experienced surfers.
On Wednesday morning, 9 September, we get a little gem: 6 ft from the WSW, 15-second period, glassy conditions with a 3 mph NNW breeze. That’s a rare, clean, small morning for the reef at Lancelin. Combined energy of 1423 – not huge, but when it’s glassy, you take it.
For the rest of the second week – from 10 September onward – the swell stays around 6 ft to 8 ft, but the wind is either onshore, fresh, or cross-shore with chop. A few mornings might be rideable, but nothing stands out as a must-do.
Crowds at Lancelin can turn up sometimes, so keep that in mind for the standout mornings. This reef needs that long-period swell to line up right, and when it does, it’s a proper session.

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.
