The Lowdown
Alright, let’s talk about this stretch of the Brittany coast. I’m Rusty, and I’ve been looking at the charts for Guidel Plages. It’s a beach and reef setup, exposed to the southwest, so it can pick up a good deal of swell. But honestly, this 16-day forecast is a mixed bag with a lot of waiting involved.
The first half of the run is rough. The week starts off with a decent 7ft swell from the west-southwest, but it’s blown-out with a cross-onshore breeze, making it lumpy and messy. The combined swell energy is a moderate 874 on Monday morning, but the wind just ruins it. By Monday afternoon, the energy jumps to 1643, but again, it’s a fresh cross-onshore mess. The water temp is about average for this time of year at 66°F.
We hit a massive gap after that. A few days of tiny, weak surf with poor conditions follow. The next time things look even slightly interesting is on Saturday morning, the 5th of September. That’s a full week away. That morning, we get a clean 4ft swell from the west with a nice 13-second period, and the wind is offshore from the north-northeast. The combined energy is a solid 480, and it’s clean. That’s the standout of the whole forecast—a proper window of good surf. The period is long, so it’ll be better shaped and more powerful, with longer lulls between sets. It’s also a bit over 5ft, so it’s not for beginners, but for the experienced crew, this is the one to target. The break is very consistent, so it’ll be running, but crowds are possible, so get in early.
The next real highlight is on Tuesday morning, the 8th of September. Another clean window with a 4ft swell from the west-southwest (11-second period) and a light offshore breeze. The combined energy is 426. It’s a solid, clean morning session, but it’s a bit smaller than the Saturday before.
After that, the forecast falls apart again. The following week is mostly small, choppy, or blown-out surf with poor conditions. There’s a glimmer on the 15th of September with a 2ft swell and an 11-second period, but it’s mixed with cross-shore wind and rain showers, so not worth getting excited about. The surf is just too small and inconsistent.
So, to wrap it up: the first week is a write-off. The clear standouts are the Saturday morning (5th September) and the Tuesday morning (8th September). Everything else is either too small, too windy, or just plain messy. If you’re patient, you’ll get a couple of clean windows, but don’t expect a long run of good waves.

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