The Lowdown
Listen up, folks, Rusty here. Let’s talk about Tronoen. It’s been a slow start, but there’s some payoff if you wait it out.
The water temp is about 65°, right where it should be for this time of year.
From Friday the 4th through Thursday the 10th, it’s completely dead. Onshore winds, choppy junk, and poor conditions for a whole week. Not worth getting wet.
Your first real chance comes Saturday the 12th morning. The wind goes offshore from the east at about 9 mph, making it clean. The swell is 4ft from the WNW with a short 9-second period and moderate energy (354). It’s not epic, but it’s the first decent wave in the whole run.
Now, Tuesday the 15th morning is the big one. That’s the standout. You’ve got a clean 8ft swell from the WNW, an 8-second period, and a massive energy reading (1438). The wind is a light offshore from the ENE at 6 mph. That’s a lot of power. At 8ft, that’s for experts only at an exposed beach break like Tronoen. The offshore wind will make it look perfect, but the average surfer should stay on the beach. The experienced crew, though, mark your calendar.
For everyone else, Wednesday the 16th morning is the goldilocks zone. A clean 5ft from the WNW (10 secs) with that same light offshore breeze from the east. Moderate energy (424). Manageable size, clean faces, and a good time. Crowds are listed as “sometimes,” so expect a few heads, but nothing crazy.
Friday the 18th morning is another small, clean option with 4ft and light offshore wind, but it’s smaller. After that, the weekend fades out again. Bottom line: the 15th for the big dogs, the 16th for everyone else.
Rusty.

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.
