The Lowdown

Alright, let’s switch to feet and miles. Rusty here with your local surf outlook for Kaolins. The forecast starts now, so let’s get into it.

The first week is mostly a headache. We start with small, weak swell and a lot of wind messing things up. The one bright spot is early on Sunday, September 13. The waves are only about 3ft from the west with an 11-second period, but the key is the glassy conditions. The combined energy is weak at 240, but with that light WNW wind, the surface will be like a mirror. It won't have much punch, but if you just need a paddle, it’s worth a look. By afternoon, the wind turns cross-on, so that window closes fast.

Monday the 14th holds a tiny 3ft west swell, but the real win is the light easterly cross-offshore wind cleaning it up. Combined energy is only 131, so it’s strictly longboard or recovery mode. From Tuesday through the following Friday, it’s pretty ugly. The wind is messy, mostly onshore or cross-onshore, and the quality is zero. Even when the swell jumps to 4ft to 6ft through Wednesday, the onshore wind rips it apart. The combined energy hits a massive 1083 Wednesday afternoon, but with a moderate cross-onshore wind, it's just whitecaps. Not worth suiting up.

Here’s the good part. Wait for Sunday the 20th. That morning is your standout. A clean 5ft west swell with a solid 15-second period gives it a combined energy of 984. And the big one: a light offshore wind from the NNE at 9 mph that will groom the faces perfectly. This is classic Kaolins (Pulau Sumbawa, Indonesia) on a reef that loves a good groundswell. That offshore wind is a game-changer – clean, hollow waves. With that long period, expect long waits between sets, and at 5ft it’s for the advanced crew only. Crowds are possible, so be ready to share. Monday the 21st also offers a clean 4ft west swell with an offshore wind and combined energy of 602 – another very good session, just a step down in size.

After that, the energy dries up. The swell fades fast through Tuesday the 22nd into the final week, with tiny leftovers and a few glassy or offshore mornings, but the wave height drops to 1ft or less. It's unsurfable. There’s a long gap of poor to no surf from late Tuesday the 22nd through the rest of the 16-day window.

The call: clear the calendar for Sunday the 20th morning – that’s your session.

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.
