The Lowdown
Alright, Rusty here again, this time in feet and miles. Let’s talk about Kaolins for the next couple of weeks. It’s gonna be a slow start, so don’t rush it.
You’re gonna have to wait a bit for the first real session. That’s Saturday morning, September 5th, at Kaolins—a reef break for advanced surfers only, and it doesn’t break often, so when it lines up, you get on it. Saturday morning brings a clean 4ft swell from the west, with a solid 13-second period. That’s a proper groundswell with some grunt (combined energy of 466), and the wind is light cross-off. Water temp is about 66°, dead average for this time of year. This is your best bet of the whole forecast: clean, good size, long period. Should be great.
After that, it gets ugly. Sunday through the next Thursday is all onshore chop and junk. Swell sizes drop under 3ft, and the energy readings are mostly weak, under 200. There’s a small clean window on Saturday morning, September 12th, with a 3ft swell and light winds, but it’s only ordinary—energy is just 147.
The second week looks cleaner for wind—offshore breezes from the northeast—but the swell stays tiny. From Tuesday, September 15th onward, you’ve got clean, glassy conditions with offshore winds, but the swell is only 1ft to 2ft at best, with long periods. Good for a longboard if you’ve got one.
Then, on Thursday, September 17th into Friday the 18th, a fresh pulse of west-northwest swell hits 5ft on Friday morning. The wind goes fresh offshore, and the combined energy jumps to 879. That Friday morning is looking like the standout of the second week—clean, stiff offshore, and real power in the water. That’s one to watch if you’re an experienced surfer. Crowds are possible at Kaolins when it’s good, so be early.
Bottom line: Saturday morning, September 5th for a clean, sizeable, long-period west swell—that’s your best. Then Friday morning, September 18th for some serious power and offshore wind. Both are worth the wait.
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.
