The Lowdown
Alright, let's break down what's coming for Guidel Plages. It's a beach and reef break open to the west, and the water is sitting around 66°F right now, which is about a degree and a half warmer than usual for the season.
The run-up to the weekend is a little quiet. Saturday morning we see a 3ft west swell with a short 8-second period — combined energy is weak (87) — but the wind is dead glassy. It's rideable but nothing special. That window is short-lived as the wind swings cross-on and it gets messy in the afternoon. The next few days are a mixed bag of small 2ft to 3ft west swells and cross-off/cross-on breezes keeping things choppy. Mid-week the energy starts to build, with Wednesday morning showing a 4ft west swell and clean conditions under a cross-offshore, but the period is still short (8 seconds), so don't expect much push.
The first real standout is Friday, 18th September morning. A 4ft swell from the west, but with a 14-second period, pumping that combined energy up to 590 — that's solid juice. The wind is a light cross-offshore from the NNW, leaving it clean. This is a proper groundswell with well-shaped waves, good power, and longer waits between sets. Because it's a beach and reef set-up, the long period might make the waves run a bit straight on the sand, but it'll be well worth it. This is your best bet for the whole outlook — aimed at the more experienced crew.
The following Saturday morning, 19th September, is also looking tidy: 3ft west swell with a 12-second period, glassy calm. Nice and clean, a good runner-up.
Into the second week, Monday 21st September is another solid shout. A 4ft west swell with a 14-second period and a moderate offshore from the NE. Energy is strong (496), and the surf should be clean and well-shaped all morning. The afternoon holds a smaller 3ft version of the same quality.
From the 22nd onward, the swell fades badly. We're looking at tiny 2ft to 2ft stuff with weak energy (under 130), and winds turn mostly onshore or cross-on. A long flat spell to finish the outlook. If you want the best of it, that Friday the 18th morning is the session to chase.
This is Rusty, out.

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.
