The Lowdown
Right, let’s have a look at the surf out here for the next couple of weeks. To be honest, it’s a bit of a slow burn. We’ve got a lot of onshore slop and lumpy conditions to wade through before we find anything that’ll get the heart rate up. The water’s currently sitting about average for the time of year, so nothing wild there.
We’re looking at a fair stretch of poor surf to start with. From Wednesday the 19th to the end of the month, it’s mostly cross-onshore and messy. The swell energy is weak to moderate, with readings like 48, 238, and 315 popping up. That WSW swell is there, but the wind keeps chopping it up. There are a few periods where it cleans up, like Saturday morning the 22nd with a gentle cross-offshore breeze and clean conditions, but the swell drops right out to 2ft with weak energy at 67. Sunday the 23rd sees a fresh offshore wind but the swell is tiny, 1ft and 33 energy. It’s just not doing enough.
We get a bit of a tease on Thursday the 27th with a light cross-onshore and 4ft of swell, but it’s only 176 energy and looks poor. Then Friday the 28th brings a bit more size, 5ft, but it’s straight onshore with a fresh breeze and only 254 energy. Poor surf, full stop.
There’s a real gap in the good stuff. We’re talking a solid week of nothing special. But keep the faith, because things start to shift towards the end of the month. Saturday the 30th has a clean morning with 3ft and 165 energy, but it’s still just “ordinary.”
The standout window opens up on Monday morning, the 31st of August. That’s the one. We’ve got a clean, gentle cross-offshore breeze, 5ft of WSW swell, and the energy jumps to 340. That’s the first real sign of life. It’s a good, clean option for Guidel Plages.
Then we get a proper punch on Tuesday the 1st of September. The morning shows 10ft of SW swell with a strong 885 energy. That’s the big one. But, and it’s a big but, that’s over the 8ft mark, so it’s for experts only. The wind is a gentle cross-offshore, so it’ll be clean, but it will be powerful. The afternoon drops to 7ft and 616 energy, still a solid swell but it gets a bit more crossed. This Tuesday morning is the pick of the whole run, but it’s got that long-range uncertainty to it. It’s promising, but we’ll need to keep an eye on it.
After that, it fades. Wednesday the 2nd is back to onshore and ordinary, and Thursday the 3rd sees a small, clean 3ft swell with 120 energy, but it’s nothing to write home about. Get on that Monday morning and be ready for Tuesday.
Alright, that’s the long and short of it. Stay stoked.

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 Guidel Plages 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.
