The Lowdown
Alright folks, Rusty here with a look at the surf ahead for Lancelin.
We’ve got a serious run of solid swell coming our way, kicking off this Sunday morning, the 9th of August. The water temp is sitting at 67°F, which is pretty much spot on for this time of year, so no surprises there.
The standout session, and the one I’d be circling on the calendar, is this Sunday morning. We’re looking at a powerful 15ft swell out of the WSW with a long 17-second period. The energy is massive (10629), and with a light 6 mph NE cross-off breeze, it’s going to be clean. This is proper, heavy groundswell. For a reef break like Lancelin, those long-period lines will be peeling nicely. But listen, at this size, it’s strictly for the experts only – over 8ft and you need to know what you’re doing.
Sunday afternoon the swell eases a touch to 13ft, but a light 3 mph NNW breeze puts a bit of a cross-on kink in it. Still big, but not quite as clean as the morning.
Monday the 10th is a write-off. Strong onshore winds and rain will make a mess of things.
Now, Tuesday the 11th is another absolute beauty. The morning has a solid 13ft SW swell with a 16-second period and a light 6 mph easterly offshore breeze – clean and lined up. The energy is still very strong (8940). Then Tuesday afternoon looks like perfection: 13ft SW swell, glassy conditions with barely a breath of wind from the SSW. That’s as good as it gets. Again, expert territory.
Wednesday the 12th through Friday the 14th still offers some excellent waves. The swell drops to a more manageable 10ft range, still with long periods from the SW. The mornings are looking best with clean easterly offshore winds. This is excellent for experienced surfers, but still solid. The afternoons get a bit of a southerly cross-shore chop, so the mornings are your window.
Into the second week, from Saturday the 15th onwards, the swell slowly backs off. We see 7ft to 8ft waves, with cleaner conditions in the afternoons. Friday the 21st afternoon looks promising with a gentle offshore and clean 7ft swell. And then Saturday the 22nd afternoon could be a sneaky good one – 8ft swell and glassy conditions. Things get a bit windier and messier from Sunday the 23rd, with strong cross-onshore winds making it a poor call.
So, to sum it up: this Sunday and Tuesday are your big, heavy-hitting days for experts. For the rest of the first week, get on the morning sessions for clean 10ft waves. The second week has smaller, cleaner windows but is less reliable.
Keep your wits about you, it’s going to be a wild ride.
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.
