The Lowdown

Right then, let’s have a proper look at what’s coming our way. Honestly, I’ve got to be straight with you – the next week is a real struggle. We’re looking at a long, frustrating gap of flat, messy conditions until things finally start waking up.

The main spot on the radar is Kaolins, a reef break that needs a specific southwest swell and clean conditions. It’s an inconsistent wave, only for the advanced crew, but when it lines up, it can be magic. Right now the water is a touch warmer than normal at 69°.

For the next several days, from Monday the 17th to Monday the 24th, it’s just poor. Wave heights are tiny, mostly 0.7ft to 3ft, with cross-onshore winds and very weak combined energy (10 to 48). Not worth paddling out for. Tuesday the 25th is more of the same.

Now, we finally get a glimmer on Wednesday morning the 26th. We’ve got some glassy conditions and a little 3ft west swell pushing in. The combined energy is still only moderate (129), so it’s not much to write home about, but it’s clean. It’s surfable, just very ordinary.

Keep your eyes on Thursday the 27th of August. The morning is glassy again with a 7ft west-southwest swell. The period is short, only 7 seconds, so it’s not a groundswell, but the glassy wind and solid height make this the standout of the entire run. The combined energy is strong (417). However, this is 7ft, which is getting into expert territory at Kaolins, especially on a steep, inconsistent reef.

After that, the swell really jacks up, but the wind turns ugly. Friday the 28th brings 10ft and then 12ft swell from the west-southwest, but it’s onshore or cross-onshore with fresh winds. The energy is very strong (1221, 1806), but the quality is garbage. This is only for the hardcore, and honestly, the setup looks more interesting for kite surfing than paddle surfing with those winds and that power.

Into the second week, the weekend of the 29th and 30th stays big. Saturday the 29th has a 10ft west swell with a longer 11-second period and strong cross-shore wind – very strong energy (3030). It’s a big, lumpy ocean. Sunday morning the 30th is a touch smaller at 7ft, but still onshore. That period is still short.

Monday the 31st and into September, the size drops back to 4ft to 7ft, but cross-onshore winds dominate again. Nothing clean.

So, to sum it up: the one and only window that has the right look is Thursday morning the 27th of August at Kaolins. Glassy, 7ft west-southwest swell. It’s a reef, it’s inconsistent, and 7ft is a serious wave, but if you’re an advanced surfer, that’s the one to circle. Everything else is blown out or flat.

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.
