The Lowdown
Alright, Rusty here. Let's talk about what we've got on the table for Kaolins.
Alright, look. Right off the bat, the next week and a half is looking like a bit of a battle. We’ve got plenty of water moving, but the wind’s just not playing ball for the most part. The water temp is sitting around 68°, which feels a *touch* warmer than usual for this time of year – you might not even need a full suit.
We kick off on the morning of the 18th with a tiny 1ft swell from the west, and a cross-onshore wind has it all chopped up. Forget it. That pattern sticks around for days – small, messy, and just frustrating. Through the 18th, 19th, and 20th, we see the swell trying to push up a bit, hitting 4ft to 5ft on the 20th from the west, but that onshore wind is just killing the shape. The wave energy is moderate (268), but it's not surfable.
You'll see a short window on the 22nd and 23rd. The wind finally clocks around to a clean offshore direction (NE and then ENE) but the swell drops right back down to tiny 1.0ft to 2ft. Clean, sure, but you’ll be scratching for scraps.
The first real glimmer of hope comes on the morning of the 25th. We’ve got a 4ft swell from the WSW with moderate energy (302). It’s still a cross-onshore wind, so it’s not perfect, but it’s the first time we get a score of 1 out of 10, meaning it’s at least rideable. The 27th of August is worth circling on the calendar, lads. Thursday morning we see the biggest swell of the whole run – a solid 8ft from the WSW, and the energy reading is a meaty 999. That is proper strong energy. The wind is light and cross-onshore. This is big stuff, over 8ft, so it’s only for the experienced crew. This could be the standout, with that WSW swell direction lining up nicely with the break’s optimum.
After that, the end of the month and into September looks pretty quiet again. The 29th and 30th of August have some glassy mornings, but the swell is back down under 3ft. The 2nd of September gives us a last little push of 3ft from the west with a clean, light cross-off wind (178 energy), but by the afternoon it’s messy and bigger again.
Bottom line: if you’re not an expert, it’s a tough outlook. The 27th of August morning is the one to hunt if you’ve got the skills and the quiver for big, powerful, a bit lumpy surf. For the rest of us, those offshore mornings around the 22nd and 23rd are the best bet for a clean, fun-sized wave, but don't expect much. Kaolins is an inconsistent reef break, and it’s living up to that here. Crowds are only sometimes a problem, so on those clean days you might have it to yourself.
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.
