The Lowdown
Alright, this is Rusty, and I’ve just had a good look at the forecast for Lancelin. Let’s get into it.
Alright, we’ve got a proper run of solid swell heading our way, but the timing and the wind are going to make or break it. The water’s sitting at 67°, which is bang on average for this time of year, so no surprises there.
The action kicks off Wednesday afternoon, the 12th of August. There’s a big 10ft SW groundswell rolling in with a period of 15 seconds, packing a strong 3285 units of energy. But the wind is a cross-shore S at 9 mph, and with that energy, it’ll be a bit lumpy and messy. The report says it’s marginal, and honestly, I’d give it a miss unless you’re desperate for a paddle.
Now, Thursday morning the 13th is where it gets interesting. The wind swings to a light offshore easterly at 6 mph, and we’ve got the same 10ft SW swell but with a longer period of 16 seconds and 4405 units of energy. That’s clean, powerful surf. The report says it’s excellent for experienced surfers, and I’m with it. That’s a standout morning for the crew who know what they’re doing. Keep in mind, with that long period, the sets will be a bit more spaced out, but the shape will be good on the reef.
Friday morning the 14th is a bit of a mix. A clean cross-offshore wind, but the tide or something has the report calling it marginal. Friday afternoon, though, the 14th, looks better. The swell drops a touch to 8ft from the WSW, still a 16-second period, and the wind is a light ESE cross-offshore. That’s clean, and the energy is still strong at 3598. That’s another good session.
The end of the first week, from Saturday the 15th through to Sunday the 16th, has some decent looking windows. Saturday morning is a bit lumpy, but Sunday afternoon the 16th is a beauty. The wind is a light offshore NE, the swell is 8ft from the WSW with a 15-second period, and it’s got 3112 units of energy. The report says excellent for experienced surfers. That’s the pick of the weekend.
Now, Monday the 17th and into the middle of the week, things get ugly. A strong NW wind on Monday, then a near gale from the WSW on Monday afternoon, with an 12ft swell that’s just a washing machine. That’s kite-surfing weather, not paddle surfing. Tuesday the 18th through Wednesday the 19th is a write-off with onshore winds and poor conditions.
The second week brings a bit of a comeback. Thursday the 20th of August, the swell pumps up to 13ft and 16ft with massive energy, but the wind is cross-onshore, so it’s going to be a choppy, messy beast. Only for the hardcore or the tow crew.
The real standout in the second week is Friday morning the 21st of August. The wind swings to a cross-offshore SE at 9 mph, the swell is 12ft from the WSW with a 14-second period, and the energy is a solid 4346. The report says it’s excellent for experienced surfers. That’s clean, powerful, and probably the best of the second week if you can get out there.
Saturday morning the 22nd also looks good with a clean cross-offshore SE wind, 10ft SW swell, and 4281 energy. Another solid session.
After that, things start to fade. The wind goes onshore again, and the swell slowly drops off through the 23rd to the 27th. The last few days of the outlook are small, onshore, and not worth getting excited about.
So, overall, if you’re looking for the best of the best, I’d be on the water Thursday morning the 13th of August and Sunday afternoon the 16th of August. In the second week, Friday morning the 21st of August is the one to circle. The rest of the time, you’ll be picking through the scraps or watching the kites fly.
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.
