The Lowdown

Righto, let’s get into it, crew. Rusty here, and I’ve been staring at the charts for Lancelin. This is a reef setup that needs a solid WSW swell to work its magic, and we’ve got a wild ride ahead over the next couple of weeks. The water temp is sitting at 66°, which is pretty much bang on average for this time of year – nothing unusual there, just standard Lanno conditions.

The overall pattern is a slow burn. There’s not a lot happening right now worth paddling out for, but the good news is that the real action is building for the back half of the outlook. The first few days are a write-off thanks to raw onshore wind and messy conditions. From Sunday August 30th, we have a clean window early, but then it gets ugly quick.

For Sunday the 30th, the morning is your only chance. We get a clean, 8ft groundswell from the WSW with an 18-second period – that’s proper long-period energy, meaning long lulls but powerful, well-shaped lines. The wind is a light 3 mph easterly, so glassy offshore, perfect. The combined energy is pumping at 4733 – that’s solid, moderate-to-strong juice. This setup is ideal for Lancelin’s reef; the long period will make the waves stand up nicely. This is the standout for the first week. After that, the wind swings onshore, and it’s a no-go.

Monday the 31st and Tuesday September 1st see the swell dropping slightly, but the wind turns to onshore on Monday and cross-off on Tuesday morning. The numbers say it’s marginal, and I’d say it’s not worth the drive. Wednesday and Thursday are messy, with the wind picking up and the period dropping.

Then we hit a proper beating from Friday September 4th through Saturday September 5th. The swell is huge – 12ft to 15ft – but it’s accompanied by 15 to 28 mph cross-onshore and onshore wind. That’s a full-on washing machine. The combined swell energy hits 8995 on Friday afternoon, which is very strong, but with that wind, it’s a kite-surfing show, not a paddle session. Don’t bother.

Now, here’s the real gold. After that wind dies down, we get an unreal run starting Sunday September 6th. Sunday morning sees a massive 16ft swell from the SW, but it’s backed by a 15 mph cross-offshore southerly, so the reef will be handling it. Combined energy is 14572 – that’s huge, experienced-only territory. The standout, though, is Monday September 7th. The swell drops to 12ft, still solid, but the wind is a light 9 mph easterly offshore. The period is 16 seconds, and the energy is 6263. That’s exceptional, clean, glassy conditions for experts. If you can handle it, this is the session to book in for.

Tuesday September 8th morning is also clean with a 10ft swell and offshore easterlies, but the afternoon gets a bit of cross-chop. The window from Sunday to Tuesday is the best run of the whole forecast.

Further out, there’s another pulse around Thursday September 10th with a 13ft swell and 18-second period, but the wind is cross-onshore to onshore, so it’s compromised. The energy is over 10,000, so there’s plenty of power, but the wind will chop it up.

To sum it up: the first week is a struggle with only Sunday morning the 30th being worth it. The true standout is Monday September 7th morning for experienced surfers. The second week has a few promising windows, but nothing beats that Monday.

Stay patient, and don’t get caught out by the mid-week wind.

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.
