The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s coming up for Lancelin.
Right off the bat, the water temp is sitting at 66°, which is just about bang on average for this time of year, so no surprises there.
The next couple of days are a bit of a mixed bag, but we’ve got some solid potential building. For Saturday the 15th, the morning session is your best bet. You’ve got a 8ft WSW swell, clean lines thanks to a light cross-offshore breeze, and the energy is pumping at 2118. It’s not perfect, but it’s the best of the early days. Sunday the 16th morning is also worth a look, with a 7ft WSW swell, a very long 16-second period, and a clean face from the NNE wind. The energy is even higher at 2191.
Now, for the real standout. If you can wait, the morning of Monday the 24th of August is shaping up to be the pick of the bunch. That’s pushing a week and a half away, so keep an eye on the forecast, but it looks promising. You’ll have a 6ft WSW swell, super clean conditions with a light breeze, and solid energy at 1216. It’s not the biggest, but the quality should be there.
The middle of the second week, around Thursday the 27th and Friday the 28th, also has some good-looking mornings. The 27th offers a 6ft WSW swell with a 17-second period and clean conditions, and the 28th bumps up to a 8ft WSW swell with a 18-second period, clean offshore winds, and a healthy energy of 3710. That Friday morning looks like a proper session for experienced surfers.
Be aware that from the 17th through the 20th, we get a big pulse of swell, but it comes with onshore or cross-onshore winds that will mess up the shape. The 18th has a massive 13ft swell, but it’s choppy and onshore, so more of a challenge than a joy. A few days around the 30th also see a big jump in size, but again, the wind is not your friend.
Overall, the consistent energy from the WSW is there, but the wind windows are tight. The early mornings are your golden hours. The 19th and 21st mornings also offer clean, offshore conditions with solid 8ft to 10ft swells, perfect for the experienced crew. The breaks are fairly consistent and exposed, so this setup tends to deliver.
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.
