The Lowdown
Hey, Rusty here.
Straight up, Kaolins is in a dry spell. The first 11 days, from Tuesday the 18th through Friday the 28th of August, offer nothing worth paddling out. Tiny, weak swell – under 3 feet most days – and cross-onshore winds making a mess of it. Combined energy is mostly below 100 (weak), so it’s a flat, frustrating stretch.
Things get a little interesting on Saturday the 29th of August, morning session. A 4ft swell out of the WSW, 10-second period, clean cross-offshore breeze, and combined energy at 315 (moderate). It’s only a marginal call, but it’s the best of a bad bunch. By afternoon, the wind swings back onshore.
The standout, and I mean the only one, is Tuesday the 1st of September, afternoon. Swell builds to 7ft from the WNW, with a 12-second period – proper long-period groundswell pumping through. Combined energy hits a massive 2239 (very strong). Problem is, onshore wind from the WSW at 9 mph, and at that size (over 8ft), it’s expert territory only. For a rare, inconsistent reef like Kaolins (advanced crew only), this could be a wild, powerful session. Expect a handful of locals – it’s “sometimes” crowded.
Water temp is about normal for the season.
Bottom line: 16 days of near-zero surf for most, with one possible banger for the hardcore on September 1st. If you’re not an expert, don’t bother. For the rest, keep an eye on that date – but don’t hold your breath.

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.
