The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
Well, we've got some size on the way, that's for sure. The main player is Lancelin, a reef set-up that needs a solid WSW groundswell to get goin', and it's about to get a whole lot of it. The water temp is sittin' at 65°, which is pretty much bang on average for this time of year, so no surprises there.
Things kick off proper on Monday morning, the 14th of September. We've got a solid 8ft swell out of the WSW, with a long 14-second period, pumping a heap of energy through the reef (2887). The wind is a light offshore from the ESE at 9 mph, so the lineup should be clean. This is proper surf for experienced crew only – it's a solid wave.
The size sticks around through Tuesday the 15th, with the morning looking best again. Another 8ft of WSW groundswell, with a 14-second period, but this time the offshore is a bit stronger at 16 mph from the east. Still, that's clean and well shaped.
Wednesday the 16th sees a drop, with the swell easing to 6ft. The wind is a cross-offshore in the morning, so it will still be rideable, but the energy is dropping right off (1314).
Now, there's a bit of a nasty spell from Thursday the 17th right through to Saturday the 19th. We get messy, onshore winds and the surf quality goes out the window. Friday the 18th looks particularly grim with a howling onshore and rain – that's a write-off. Even the big 10ft to 12ft swell on the 18th and 19th is just going to be a blown-out mess.
The real standout window is Sunday morning, the 20th of September. After all that wind, the ocean goes completely glassy, with the wind dropping to just 3 mph from the north. There's still a clean 7ft swell (1442) from the WSW with a 13-second period. This is the pick of the whole forecast – clean, powerful, and a touch of magic in the air.
After that, the wind gets a bit dicey again, but we get another clean shot on Monday the 28th of September. The morning has a light cross-offshore breeze and a consistent 7ft SW swell (1792). It's a long way out, so not as certain, but the potential is there.
Right at the very end of the run, on the 27th and 28th of September, the wind goes offshore again. The 27th afternoon looks particularly nice with a gentle offshore breeze and a 7ft WSW swell (2271). Again, that's deep in the forecast, but it's something to keep an eye on.
The biggest, most powerful swell of the whole run hits on Saturday the 26th of September. We're looking at a 15ft swell from the WSW with an 18-second period, and a huge 11885 combined energy. That is massive, but the wind is a cross-offshore, so it might just hold together. That is for experts only, and even then, it's going to be a handful. It's a long way out, so treat it as a promising possibility.
So, to keep it simple: Sunday the 20th is your best bet for clean, powerful waves. If you want the biggest, meanest swell, circle Saturday the 26th of September, but be prepared for a beast.
Rusty.

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.
