The Lowdown

G’day, Rusty here, with a proper look at Lancelin for the next couple of weeks.

Right now, the opening days are packing a punch, but the window for truly clean conditions is tight. The standout period is the first weekend, with a serious groundswell rolling in. Friday the 21st of August is the pick of the bunch, offering the best chance at a good session.

We kick off Friday morning at Lancelin with a solid 10ft swell straight out of the WSW, a long 15 seconds between waves. The combined energy is a hefty 3574, which is decent juice. Wind is a clean 12 mph offshore from the east, making for good, lined-up waves – this is proper expert territory though, with the size well over 8ft. The water temperature is sitting at 66°, which is bang on average for this time of year, no worries there. Friday afternoon holds a similar 10ft WSW swell with cross-off wind, still clean but not as perfect as the morning.

Saturday the 22nd sees the swell hold at 10ft, but the wind swings around. Morning brings a light cross-on breeze, and the period jumps to 17 seconds – very long period groundswell. On a reef setup like Lancelin, those long lines might wall up a bit too straight, so take that into account. Conditions are marginal, and by afternoon a fresh 19 mph cross-shore wind chops things up badly.

Sunday the 23rd drops a bit, with 5-6ft WSW swell. The period is still decent at 13-14 seconds, but consistent cross-shore wind keeps it messy. Not worth getting too excited.

Monday the 24th is worth a mention. The morning session serves up a 8ft WSW swell with glassy conditions – literally 3 mph WSW wind, dead calm. The combined energy is 2838, and those waves will be smooth and clean. Still expert level size, but that glassy surface is a beautiful thing.

The rest of the first week fades fast. Tuesday and Wednesday see winds turning nasty. Wednesday the 26th gets hammered by a huge 13-15ft WSW swell with strong cross-onshore wind, energy in the 12-13,000 range, making it pure chaos. Kite surfers might love that mess, but for paddle surfing, it’s a hard pass.

Things clean up a little Thursday the 27th morning, with a cross-off breeze and a 12ft WSW swell – still very big, but cleaner.

The last of the good news comes Friday the 28th with a 7ft SW swell and an offshore breeze in the morning, light and clean. Size is manageable for strong intermediates, but it’s not the big juice of earlier.

From there, into the first week of September, it’s a long run of poor conditions. The swell stays up around 7-13ft, but wind is mostly onshore or cross-onshore, often strong, with combined energy climbing back over 5000. The morning of Tuesday the 1st of September is slightly less chaotic, with gentle wind, but the swell is 12ft and bumpy. The whole first week of September looks unappealing, with a few gaps of several days offering nothing decent.

There is no single other break to jump to here at Lancelin – it’s just this reef, and this forecast. So take your chance Friday the 21st morning, or maybe the glassy Monday the 24th morning. After that, it’s waiting on a change.

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.
