The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Guidel Plages over the next couple of weeks.
First thing's first: the water temp is sittin' at a warm 68°, which feels a touch warmer than normal for the time of year. That's a nice little bonus if you're paddling out without a full suit.
Truth is, for the next week or so, it's a bit of a write-off. Strong winds are gonna be the story, and they're comin' from the wrong angle – mostly cross-onshore or onshore. The swell energy is weak to moderate early on, with readings between 22 and 384 (combined energy). Saturday the 22nd of August morning is about the best of a bad bunch with a tiny 2 ft swell from the west, but it's clean with a cross-off breeze. Honestly, it's barely worth the paddle.
We get a spike of energy around the 26th and 27th of August. Swell heights jump up to 7 ft and 6 ft, and the combined energy hits 610 and 819 – solid, powerful stuff. But the wind is still howling from the south and southwest, turning it into a messy, choppy mess. Not for the faint-hearted, and definitely not clean.
The real stand-out window doesn't open up until Thursday the 3rd of September. That's the one to circle on the calendar. We've got northeast wind swingin' offshore, blowin' clean at 9 to 12 mph. The swell is a consistent 5 ft from the southwest, with a short period of 7 seconds, but the combined energy is a solid 213 to 224 – moderate energy, but with that offshore wind, it's gonna be glassy and lined up. This is the best on offer. It's a beach and reef setup, and it's very consistent, so you'll get waves. Just be aware that crowds are possible here from time to time.
The following day, Friday the 4th of September, still looks okay with a 4 ft west swell and a cross-off breeze, but the energy drops off a bit.
So, to sum it up: the first week and a half is mostly a bust. Sit tight. The clear winner is Thursday the 3rd of September. Set the alarm for that one.

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.
