The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast.
It’s a pretty grim start, I’m not gonna lie. We’ve got a solid week of below-par, onshore junk to wade through before things settle down. The wind’s just not playing ball, and the swell is messy. The first week is a write-off unless you’re desperate for a paddle.
We kick things off on Saturday, 29 August, with a stormy feel. A 8ft SW swell at 8 seconds is being blasted by a 22 mph WSW wind. The combined energy is moderate at 692, but with winds howling onshore and that short period, the surf is ugly. It’s big enough to be tricky for beginners, but no fun for anyone. This soupy, lumpy mess carries right through the weekend and into Monday. On Monday afternoon, the swell jumps to 7ft from the W at 10 seconds, hitting a combined energy of 1289, which is a lot of power, but that fresh cross-onshore 19 mph wind just tears it apart.
The first real window of hope pops up on Tuesday, 1 September. Early morning, the swell drops to 3ft from the W at 9 seconds, combined energy of 165, but the wind goes glassy. That’s a massive positive. Guidel Plages will have clean, if small, waves. It’s a brief moment though. The glass gives way to a moderate cross-onshore by afternoon, and the swell runs out of steam.
After that, we’re back into a frustrating pattern of weak, onshore slop for days. Wednesday, Thursday, Friday, and Saturday all offer nothing worth suiting up for. The swell barely hits 3ft most of the time, and the wind is either on or cross-onshore. A small, clean window appears at the end of the week on Sunday, 6 September, but the swell is a tiny 3ft from the W, so you might find a knee-high peel if you’re lucky.
Monday, 7 September afternoon gets interesting. A clean, cross-offshore wind from the N at 9 mph cleans up a 4ft W swell at 9 seconds, with a combined energy of 263. The conditions are clean, but the forecast calls it marginal, so tide will be the key. It’s worth a look if you can.
The second week gets weird. Tuesday, 8 September is clean again, but the swell stays small. Wednesday, 9 September offers the cleanest morning of the run with a light cross-offshore NNE breeze at 6 mph, but the swell is only 2ft from the W.
Thursday and Friday look poor. By Saturday, 12 September, we see the return of fresh cross-onshore wind and lumpy surf with a 4ft WSW swell. Nothing to get excited about.
The very last day in the window, Sunday, 13 September, presents something unusual. A clean cross-offshore breeze with a 3ft WSW swell that has a very long period of 16 seconds. Combined energy is moderate at 258. That’s groundswell. The long period will make it more powerful than the height suggests, and at Guidel Plages, a reef/beach setup, it might create some decent lines before the wind shifts. It’s the standout of the whole two weeks, but it’s far out, so keep an eye on it.
The back half of the fortnight is uncertain, but this long-range call at least offers hope. For now, just watch the tides and hope for a change.
Stay salty,
Rusty

Information about the Guidel Plages Surf forecast

A general guide to surfing at Guidel Plages can be found by selecting the local surf guide option on the grey menu.

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.
