The Lowdown
Alright folks, Rusty here. Let's get into it. We're looking at a tough 16-day stretch for Sainte-Barbe, a reef setup that really needs a clean, lined-up swell and the right wind to turn on. To be honest, it’s a lean period, but there are a couple of windows to keep an eye on.
The water is sitting at 67°F right now, which is about 2°F warmer than usual for this time of year – feels a little bit like summer is holding on.
We start with a tease on Tuesday morning, the 1st of September. There's a 3ft swell from the west with a 10-second period, clean and glassy with a light NE breeze. The energy is weak at 179, but it would be surfable. Unfortunately, it doesn't hold. The wind shifts onshore that afternoon and the swell drops, and we’re looking at a solid run of poor conditions with tiny, choppy waves right through until the end of the first week. The swell energy drops into the double digits – 32, 20, 72 – just no power or shape.
There’s a small pulse on Saturday the 5th. The morning shows 3ft from the west, and the wind is offshore from the ENE. It’s clean, but the energy is only 185, making for weak, ordinary waves. The afternoon goes glassy with 2ft, which is better but still small.
Now, here’s the standout. Mark Friday the 11th of September in your calendar. The morning brings a 5ft swell from the west-southwest, pushed along by a clean offshore NNE breeze at 9 mph. The energy jumps up to 522, which is solid, and the 8-second period is short but punchy. This is the best we’re going to see. It’s still a reef break that is inconsistent, and at 5ft, it’s starting to get sizey, so it’s one for the experienced crew. The afternoon holds at 5ft with a cross-offshore wind, still clean and good.
After that, the swell backs off. We get a small, clean window on the 15th of September – Tuesday morning – with 3ft from the west-southwest and a long 12-second period. That longer period gives it some shape, and with a light offshore wind, the morning session could be fun if you need a wave, but the energy is moderate at 240. The afternoon gets chopped up by the onshore wind.
For the rest of the run, it’s mostly small, messy, or wind-affected. The 5ft pulse on the 11th is your one true winner in this outlook. Get on it if you can.
Rusty.

Information about the Ste Barbe Surf forecast
The above surf forecast table for Ste Barbe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ste Barbe can be found by selecting the local surf guide option on the grey menu. Our Ste Barbe 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 (Ste Barbe) 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 Ste Barbe 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.
Ste Barbe is 22 km (14 miles) from the city of Lanester. If you plan a holiday in Morbihan - Brittany, look for hotels and other accommodation in Lanester. Lanester has rooms for a wide range of budgets as well as car hire and transport links.
