The Lowdown

Alright, surf’s up... well, sort of. Let’s be honest, the next few days are gonna test your patience more than your pop-up. We’ve got a real slow burn here at Guidel Plages. The first couple of days, the ocean’s just not doing much for us.

Tuesday the 15th is a write-off. Tiny, weak swell with a cross-shore breeze that’s just chopping everything up. Water’s sitting at 19°, which is a touch warmer than normal for this time of year, so you won’t need the thickest suit, but you’ll be doing more floating than surfing. It’s a beach and reef setup, and right now, it’s looking pretty flat and messy.

Wednesday the 16th shows a bit of life, but it’s still pretty average. The swell bumps up to 1.3m in the morning with a clean cross-offshore wind, but it’s a short-period 8-second wave, so it’ll be a bit crumbly. The afternoon sees the size jump to 1.9m, and the energy is building (1092), but there’s a moderate cross-offshore breeze that will keep it from being great. It’s surfable, but I wouldn’t call it a winner.

Then we hit a real rough patch. Thursday the 17th through Saturday the 19th, forget it. We’ve got onshore winds, lumpy, choppy conditions, and poor surf quality. The swell is there at times, but it’s just a messy, wind-blown mess. You’re better off finding something else to do.

Now, here’s where it starts to get interesting. Sunday the 20th, the morning is looking like our first real chance. It’s still small at 1.0m, but the wind goes glassy. Absolutely glassy. That’s a huge positive. It’s clean, it’s calm, and while the waves are small, it’s the best conditions we’ve seen in days. That’s a good one to get wet for, even if it’s just a longboard session.

The next few days are a mixed bag. Monday the 21st has a bit more size and a clean cross-offshore wind, but the swell period is up to 13 seconds, which is a bit longer and can make it close out at a beach break. Tuesday the 22nd is back down in size, and Wednesday the 23rd is ordinary. Thursday the 24th stays small with clean morning conditions, but nothing exciting.

Okay, now let’s talk about the real standout. Friday the 25th. The morning is looking clean with a cross-offshore breeze, but here’s the kicker – the swell period jumps to 14 seconds. That’s proper groundswell. It’s not huge, 0.8m, but it’s got that long-period push that makes the waves feel way better than the size suggests. And it’s clean. That’s our pick for the best surf of the week.

But the true gem is further out. Wednesday the 30th. This is the one I’m circling on the calendar. The morning is looking right. Swell bumps up to 1.7m from the WSW, the period is a solid 11 seconds, and the wind is a clean cross-offshore from the east. The energy is moderate (751), but everything is lining up. It’s a good size, it’s clean, and it’s got some push. This is a proper surf day. The afternoon gets a bit onshore, so get your session in early.

Keep in mind, this is a long-range call, so don’t book the day off work just yet, but if it holds, Wednesday the 30th is the best bet on the board. Before that, Friday the 25th is your next best window. Everything else is just waiting for it to turn on.

Anyway, that’s the long and short of it. It’s a lean stretch for a while, but there are a couple of gems hidden in there. Keep your eye on the forecast, and I’ll see you out there.

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.
