The Lowdown
Alright, this is Rusty. Let’s get right into it. We have a solid run of surf on offer here, all at one standout reef break: Chameau. There is no gap at the start – the action kicks off on Tuesday morning.
Things start a little on the smaller side Tuesday morning, with 4ft south swell, period a decent 12 seconds, and cross-offshore east winds at 16 mph. Combined energy is moderate (694). The water here is sitting at 77°, which is a touch warmer than normal for this time of year. Tuesday afternoon cleans up nicely: the wind goes offshore, and you’ve got 4ft south swell, 12-second period, energy at 612, and the report says expect very good surf. It’s a nice little intro.
Wednesday and Thursday stay in that same zone – clean, offshore winds, but the swell drops a bit. Wednesday morning has 4ft south swell, 11-second period, gentle offshore breeze, energy at 423. It’s good, but not the headline.
Now, things start to build from Friday the 21st. Friday afternoon you get 4ft south-southwest swell, period up to 14 seconds, gentle offshore wind, and energy jumping to 751. Saturday the 22nd pushes up to 5ft to 6ft, still that great 14-second period, energy climbing to 990. Clean conditions all the way.
Sunday the 23rd is where it gets real. The swell hits 7ft from the south-southwest, 14-second period, and the energy jumps into the strong range at 2001. Winds are light and offshore. This is excellent surf, but that 7ft size is getting into expert-only territory at a reef break. Monday the 24th stays in that sweet spot: 6ft swell, period bouncing between 13 and 15 seconds, energy staying well over 1000. Still clean.
Tuesday the 25th has another push: 7ft swell, 14-second period, energy at 1670. Clean and excellent, but again, that size is for experienced surfers.
The standout is Wednesday the 26th. 10ft of south-southwest swell, an exceptional 16-second period, and combined energy of 5026. Gentle offshore morning winds. This is a proper, powerful groundswell for experts only. It will be a serious session for those who know what they’re doing.
After that, things get chaotic. Thursday the 27th sees the swell jump to a massive 20ft with strong south winds and energy at an insane 28500. That’s too big for this break. The following days from the 28th through to the 2nd of September still have solid swell (7ft to 12ft), but the winds turn fresh and strong, and the reports start calling it marginal. There’s still surf, and it’s offshore, but it’s a battle. The energy numbers are through the roof, but the quality drops because of the wind strength and sheer size.
For the best, cleanest, most powerful surf in this window, your two days are Sunday the 23rd and Wednesday the 26th of August. The 26th is the absolute peak for wave quality, but only for experts.
Keep your wits about you on the bigger days. Chameau can handle it, but it commands respect. This is a consistent reef, so it’ll be breaking. Expect crowds sometimes.
Rusty.

Information about the Chameau Surf forecast
The above surf forecast table for Chameau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chameau can be found by selecting the local surf guide option on the grey menu. Our Chameau 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 (Chameau) 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 Chameau 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.
