The Lowdown
Hey, Rusty here again. Let’s talk swell in feet and miles per hour.
The first week is a total write-off. From Wednesday the 26th of August right through to Monday the 31st, the sea is a mess. It’s all onshore and cross-onshore winds, with a sloppy, choppy surface. We see some bigger numbers, like a 7ft pulse on Saturday the 29th, but the wind is howling onshore at 20-22 mph, ruining any chance of a clean wave. The water’s about 65°F, which is normal for the season, so nothing to mention there.
The first glimmer of hope comes on Tuesday the 1st of September morning. The swell drops to around 5ft from the west, period around 9 seconds, with a light cross-onshore breeze. It's only a marginal call, but it’s the first time you can look at the ocean and not just turn around.
The best window by far is Monday the 7th of September morning. We’re looking at a 6ft groundswell from the west-southwest, with a 10-second period. The wind is light and cross-shore out of the SSE. It’ll be a bit lumpy at first, but that’s the session to keep an eye on. The combined energy is solid.
But the clear winner, the day you want to be in the water, is Tuesday the 8th of September morning. A light offshore breeze from the north at just 6 mph will groom a 4ft swell from the west-southwest. The period is 9 seconds, and the combined energy is moderate, but that offshore wind will make it glassy and clean. Expect some crowds, but for those clean, lined-up waves, it’s the only game in town.
After that, it fades back into small, clean but weak surf through the 10th.
In short: survive the first nine days, then smash Tuesday the 8th of September morning.
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. If you surf the same spot (Guidel Plages) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
