The Lowdown
Well, I'll be honest with you, this is a tough one. For the next 16 days, Guidel-Plages is looking like a real struggle. We've got a long stretch here where the conditions are just not cooperating.
For the first several days, starting Monday the 17th of August and running right through the week, the onshore and cross-onshore wind is just relentless. You're seeing a mix of W and WSW winds, and while the swell does try to build a little, the wave direction is W, but the wind is just tearing it up. Swell heights from 1.0 ft to 5 ft, but it’s all suffering from a strong cross-chop. The combined energy of all swells gets into the moderate range, hitting 331 on Thursday the 20th, but with that fresh cross-onshore wind and a rough sea state, it's just not worth the paddle out.
We finally get a glimmer on Saturday the 22nd of August in the morning. The wind swings around to a clean offshore from the ENE, light breeze, and the water looks clean. The problem is the swell is tiny – just 2 ft from the west – and pretty weak. The combined energy is only 53. It’s surfable, but it's very ordinary.
There's another brief taste of that offshore wind on Sunday the 23rd and Monday the 24th, but again, the swell drops even further to 0.7 ft and 1.0 ft. The energy is basically non-existent. We're talking about a really poor run.
Then we hit a big gap. From the 25th of August through the end of the month, we're back into a westerly onshore flow. The swell does try to kick up again, with the 29th of August showing a 8 ft swell from the SW, and combined energy hitting 467 – which is strong – but it's all big and messy. The wind is still a fresh cross-onshore. This is expert-only territory if you want to try it, but honestly, the wind is so bad for Guidel-Plages that it's hard to recommend even to the die-hards. It might be more interesting for the kite surfers than for us paddle guys.
For the very end of the outlook, on the 1st of September, we see it dropping back down, and the onshore wind is still there.
There is no stand-out session here. The only one that I’d even consider a hope is the Saturday the 22nd of August morning. The offshore wind is a major positive, but the swell is just too small to make it a proper surf. It’s one for the longboard if you’re desperate for a paddle. For the rest of the 16 days, we are looking at gaps of several days with no real recommendation. It’s a blank run, which happens in this area. The forecasts can change, but right now, we're stuck.

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.

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.
