The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up. It's a bit of a mixed bag, so let's get into it.
The immediate outlook is pretty quiet with only small, ordinary waves on offer through the weekend. Things start to look more promising from the middle of next week, with a solid pulse of long-period groundswell and clean conditions lining up for a standout window. After that, we drop back into small, clean but weak surf for the second week, with very little energy on the cards.
We'll kick things off at Kaolins, a reef setup that's inconsistent and for advanced crew only. The water is sitting at 66°, which is a touch warmer than normal for this time of year.
Sunday, September 13th has some small 3ft swell from the west with an 11-second period. The morning is looking glassy with barely a breath of wind, so it'll be clean despite the ordinary conditions. The combined wave energy is weak at 240. The afternoon turns cross-onshore and choppy, so not worth it.
Monday, September 14th is smaller again, 3ft west swell, period dropping to 9 seconds. The morning is glassy but the energy is weak (131). The afternoon turns onshore.
Tuesday, September 15th is tiny and weak. Morning has 2ft west swell at 8 seconds (energy 79) with a cross-shore wind. Afternoon sees a bit more size at 3ft but with a moderate cross-chop (energy 165). Not good.
Wednesday, September 16th morning shows a bit of a pulse: 4ft west swell at 9 seconds, with a clean cross-offshore wind. Energy is moderate at 235. It's surfable but nothing special. The afternoon jumps to 6ft west-northwest swell at 10 seconds, but a moderate cross-shore and chop ruin it. Energy is strong at 986.
Thursday, September 17th is all onshore junk. 4ft to 5ft west swell, period 10 seconds, but with moderate to fresh cross-onshore winds and rain. Not for it.
Friday, September 18th is where it gets interesting. The morning brings 6ft west swell with a *very long* 16-second period. This is proper groundswell, with strong wave energy (2266). Conditions are a bit cross-onshore and choppy, so it's marginal. Still, that's a lot of water moving. The afternoon is a no-go with fresh cross-onshore winds.
Saturday, September 19th is back to messy, onshore conditions with 4ft swell.
Sunday, September 20th is a reset. Morning sees 3ft west swell at 10 seconds, clean with a cross-offshore breeze. Energy is moderate (214). It's surfable but ordinary.
Now, here's the standout. Monday, September 21st is the best on offer. Morning has 4ft west swell at a solid 14-second period, combined energy at 476 (moderate). With a light cross-offshore wind and clear skies, it's clean and lined up. The afternoon is even better: 3ft swell at 13 seconds, still clean with a light cross-offshore breeze. Expect good surf conditions both sessions. This is the one to aim for.
Tuesday, September 22nd sees the swell drop back to 2ft. The wind goes offshore but it's fresh at 25-30 mph, making for clean but tiny, blown-out conditions. Not worth a paddle.
Wednesday, September 23rd through to Sunday, September 28th is a long stretch of small, clean but weak surf. Swell heights hover between 0.7ft and 2ft, with periods varying. Energy readings are very low, mostly under 100. The wind is often cross-offshore or light, so it looks pretty but there's just no power. This is a real lull.
Monday, September 28th sees a tiny uptick to 2-3ft west swell with 12-13 second periods, energy around 200. Clean with cross-offshore winds, but still very small. A poor end to the outlook.
So, to sum it up: the first week is mostly ordinary, but Monday, September 21st is the clear standout with clean, solid groundswell. After that, we hit a long, quiet spell that lasts well into the second week.
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.
