The Lowdown
Alright, let's get into it. I've been staring at this run of charts for Guidel Plages and honestly, it's a tough stretch for the paddle crew.
Right up front, it's looking pretty flat and messy around here. The water temp is sitting at about 67°, which is pretty much normal for this time of year, so no surprises there, but you wouldn't know it from the surf.
We start on Wednesday afternoon with a weak 2ft swell from the WSW. It's carrying a weak energy (75) and the wind is howling cross-onshore, so it's a total choppy write-off.
Thursday isn't much better. Thursday morning we get a tiny bump to 3ft, but the onshore wind is still ruining it. The afternoon is the same story with a stronger onshore breeze picking up. It's poor.
Friday the 14th morning is the first little glimmer. We get a clean, cross-off breeze and a 2ft swell. It's surfable, but the energy is weak (75) and the period is short (9 sec). It's ordinary. Friday afternoon the wind swings back onshore and chops it up.
Saturday the 15th morning is clean again with a 3ft swell from the W, moderate energy (117). Again, it's just surfable, nothing to get excited about. Saturday afternoon drops off.
Sunday and Monday are flat and weak. Sunday has clean conditions but tiny waves. Monday is a complete dud with a 1ft swell and almost no energy (10).
We get a brief lift on Tuesday the 18th morning. A clean 3ft swell from the WNW, moderate energy (130), but the cross-off wind will keep it tidy. Still, it's just a tease.
There's a long gap of poor conditions and onshore wind through Wednesday, Thursday, and Friday.
Now, let's talk about the one actual stand-out in this whole 16-day window. Saturday the 22nd of August is your best bet. Saturday morning sees a nice clean 4ft swell from the WNW with good energy (267) and a light offshore wind from the NE. The conditions will be clean. The swell direction matches what this spot needs (SW). It's not huge, so it's good for almost everyone, and since this break is very consistent and exposed to the swell, it should be fun. Keep in mind, crowds are possible here sometimes, especially when it's the best in town. Saturday afternoon, the wind shifts onshore, so make sure you're out early.
After that, the forecast falls apart. Sunday the 23rd is tiny again, and the rest of the run into late August is a mix of weak swells, onshore wind, and messy conditions. There's another little bump on the 26th with a 5ft swell from the WNW, but the cross-shore wind is strong (18 mph) and the energy is strong (512), which will create lumpy, bumpy conditions. At that size and with that wind, it's more interesting for the kite crew than for a surfer looking for a nice ride.
So, to be blunt: there's one morning to aim for, Saturday the 22nd. Get up early. The rest of the forecast is a waiting game.

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.
