The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next week and a half at Guidel Plages is a tough watch. We’ve got a real dry spell on our hands, with a whole lot of onshore wind and messy conditions. Don’t get your hopes up until we get into the second week.
We start off weak. The first few days, from Thursday the 3rd to the middle of the following week, are basically a write-off. The wind is mostly onshore or cross-onshore, and the swell is short-period, wind-driven junk. The combined energy of all swells directed here is weak, bouncing around (122) to moderate (135). It’s just poor surf conditions, day after day. There’s a little window on Saturday morning the 5th where a 4ft W swell rolls in with a 13-second period, but the wind is cross-off from the E. The energy jumps to (459), but it’s only a morning window before the wind swings back onshore. It’s not enough to save the weekend.
We then hit a long gap. From Saturday afternoon all the way through to Monday the 14th, it’s the same story: poor conditions, choppy, lumpy, and onshore. The water temp is sitting around 66°, which is about average for this time of year.
Now, here’s the light at the end of the tunnel. The standout window is Tuesday the 15th. The morning sees a long-period groundswell arrive, 3ft from the WSW, but with a 16-second period. That’s a very long period swell, which means proper energy and shape. The wind is offshore from the NE, making it clean. The energy reading is moderate (395). By Tuesday afternoon, it gets even better. The swell bumps up to 4ft from the WSW, the period extends to 17 seconds, and the wind stays offshore. The combined energy jumps to a strong (947). This is the one to wait for. Guidel Plages is a beach and reef setup, and this long-period groundswell will work best on the reef sections. Just be aware that with a consistent spot like this, crowds are possible.
Wednesday the 16th morning is also a solid option. The swell is still 4ft from the WSW, with a 14-second period, and the wind is a clean cross-off from the ENE. The energy is strong (694). It’s a great follow-up session after the Tuesday winner.
The rest of the outlook fades back into small, weak waves. Thursday the 17th morning has a glassy 2ft from the west, but it’s only 11 seconds, and the energy is weak (125). It’s more of a cruise than a highlight.
So, to sum it up: don’t bother before the 15th. The real deal is Tuesday the 15th afternoon at Guidel Plages. That’s the one to circle on the calendar. The forecast is a ways out, so keep an eye on it, but it looks like a proper session.
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.
