The Lowdown

Alright, let's break down this swell window for Kaolins. It's a bit of a slow burn for the next two weeks, and you're gonna need some patience.

The early part is a total write-off. Wednesday the 26th has a dribble of swell, maybe ankle to knee high, but it's crossed up and junky. Through the next week, it's a constant onshore wind battle. We see swell pop up to 4-5 feet on the 29th, but it's blown out and lumpy. The energy readings are telling the story, like 440 and 748 on that Saturday—that's a lot of churn, but no shape. It's not worth suiting up for that mess.

We finally get a glimmer of hope on the Saturday of September 5th. The swell isn't huge, about 4-5 feet, but the wind is supposed to swing offshore in the morning. That's a game changer. The 11-second period will give it some push, and the energy is in the moderate range. It's a window to watch, but it's far out, so don't book your flights yet.

But the real standout is September 10th. This is the one that has me stoked. The models are showing a proper groundswell filling in, head-high to well-overhead at 5-6 feet. But get this—the period is up to 12 seconds, and the combined energy is at 1306, which is strong. That's real juice. And the wind is supposed to be offshore in the morning, making for clean, glassy conditions. This is a proper reef-break session. The long period means it'll be powerful and lined up, a real test of your skills. It's an advanced wave, so be ready. The early morning looks mint, with the afternoon more cross-off but still very good. This is your window. Don't sleep on it.

Before that, it's mostly a holding pattern. The 8th and 9th have some glassy, clean mornings, but the swell is tiny. The water temp is about normal for this time of year, so you won't need a hood unless you're tough. Just remember, September 10th is the day to point your car towards Kaolins. It's a long way off, but the potential is there for a proper session.

Stay patient. It's coming.

Rusty.

Information about the Kaolins Surf forecast

The above surf forecast table for Kaolins provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kaolins can be found by selecting the local surf guide option on the grey menu. Our Kaolins 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 (Kaolins) 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 Kaolins 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.

Kaolin is 5 km (3 miles) from the city of Ploemeur. If you plan a holiday in Morbihan - Brittany, look for hotels and other accommodation in Ploemeur. Ploemeur has rooms for a wide range of budgets as well as car hire and transport links.
