The Lowdown

Alright, let's get into it. This is for Tronoen, and it’s a bit of a tough stretch. The water is 63°F right now, which feels a touch colder than we’d expect for this time of year.

Looking at the whole 16 days, the honest truth is there are no good surf options. The first few days are a write-off. Monday the 24th and Tuesday the 25th have tiny, weak swell with nothing to ride – you’re looking at 1ft to 2ft and the conditions are just poor. The combined energy is weak, barely registering (21). You’d be better off staying at home.

Wednesday the 26th morning has a little bump to 2ft and the wind is light and cross-off, so it’s clean. But the energy is still weak (123) and the period is short, so it’s just not going to be any fun. It’s a “maybe if you’re desperate” sort of day.

Then from Thursday the 27th, the swell picks up but the wind turns on it. We see 6ft to 8ft of swell for the next few days, but the problem is that the wind is onshore or cross-onshore and gets strong. Friday the 28th and Saturday the 29th are especially nasty with 19-22 mph winds and lumpy, choppy conditions. The energy gets moderate to strong (up to 663), but it’s all messy. Even the bigger days, like Monday the 1st of September with 6ft, are blown out.

There is a long gap here with no real recommendation. The wind and swell just don’t line up for a clean wave until the very end of the forecast.

The only real standout, and it’s a promise that’s a long way off, is Tuesday the 8th of September. This is two weeks away, so take it with a grain of salt, but it looks like the real deal. The forecast shows a massive groundswell from the W with a very long period of 18 seconds and a combined energy reading of 5471. The swell is 10ft to 12ft. That’s big, expert territory, way too much for beginners. The wind is clean and light, which is a big positive. The catch is that the swell is predicted to be too big for Tronoen itself. For a spot like this, that kind of long-period, powerful swell might break too straight, but if you’re an expert and you know where to sit, it could be a monster session. But it’s a long way out and needs to be watched.

So, for the next two weeks, it’s a waiting game. The forecast can change, but right now, there’s not much to get excited about until that big one in early September.

Information about the Tronoen Surf forecast

The above surf forecast table for Tronoen provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tronoen can be found by selecting the local surf guide option on the grey menu. Our Tronoen 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 (Tronoen) 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 Tronoen 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.

Tronoen is 13 km (8 miles) from the city of Loctudy. If you plan a holiday in Finistere - Brittany, look for hotels and other accommodation in Loctudy. Loctudy has rooms for a wide range of budgets as well as car hire and transport links.
