The Lowdown
Alright, Rusty here. Let’s break down what’s heading for Guidel Plages.
It’s a slow start, no two ways about it. The early days are pretty lackluster with small waves and messy wind. Gonna need some patience through the first week, but the second half of the forecast brings something much more worthwhile.
Thursday the 10th and Friday the 11th are a bust. Tiny waves, choppy surfaces, poor conditions. Don’t bother.
Saturday morning the 12th offers a little relief. The ocean goes glassy with light offshore wind and a small 3ft west swell. The energy is weak (55). It’s surfable, but just barely. A sunrise session on a longboard might give you a few clean little runners.
Sunday the 13th morning sees the swell pick up to 3ft from the west, with a longer 11-second period. The energy bumps up to 244 (moderate). Wind is light and cross-onshore, so it’s not perfect, but the waves will have more shape. Still only marginal though.
Monday the 14th morning is clean with a light cross-offshore breeze. Swell drops back to 3ft, but with clean conditions, it’s a decent small-wave option.
From the 15th through the 23rd, it’s a real mixed bag. Most days have poor conditions, strong winds, and inconsistent small swell. There are brief clean windows, like Wednesday the 16th with a 5ft west swell and cross-offshore wind, but the energy is moderate (293–382) and the overall quality is still marginal. A few sessions here and there, but nothing special.
Now, the big one. It’s a long way out, but keep your eyes on Friday the 25th of September. The morning brings a solid 7ft west swell with a very long 14-second period. The combined energy is massive at 1884 (strong). Winds are clean and cross-offshore from the east. This is a proper groundswell. The water temp is a touch warmer than normal at around 66°F. At 7ft, this is expert territory – powerful, with lots of water moving. This long-period west swell will wrap into Guidel Plages nicely, offering long, clean lines. The afternoon sees it ease to 6ft, still very solid. Crowds are sometimes an issue here, and on a day this good, you can bet it’ll be busy.
So to sum it up: The first week is mostly for those who just want to float around. The real standout is Friday the 25th morning – big, clean, powerful west groundswell. That’s the one you want to plan for.
Rusty.

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.
