The Lowdown
Alright folks, Rusty here. Let’s have a look at the swell window for Tronoen over the next couple of weeks. I’m not gonna sugarcoat it: this stretch is a real test of patience. We’ve got a long, drawn-out period of small, often messy surf, with only one proper window that looks like it’ll actually get the heart rate up. The first week is mostly about small waves and onshore chop, so if you’re keen, bring a groveler and low expectations.
The water temp is sitting at 65°, which is pretty much bang on average for this time of year, so a good summer wetsuit will do the trick.
Right, let’s get into it. The first real mention of anything surfable is the morning of Monday the 10th. It’s only 2ft of NW swell with a 9-second period, but the light N cross-off wind keeps it clean. The energy is weak though, sitting at 100, so it’s not going to be lighting the world on fire. There’s a similar blip on Wednesday morning the 12th, with 3ft from the W at 10 seconds, and light SE winds keeping it clean, but again, it’s just ordinary.
The weekend of the 16th and 17th has some small, clean mornings with light offshore winds, but the swell is tiny and the energy is weak. It’s a classic “splash around on a mal” kind of vibe, not a “call in sick to work” kind of vibe.
Then things start to get real towards the end of the second week. The swell starts building, but the wind is set to blow hard from the west and northwest, making a mess of things. Thursday the 20th sees the swell jump to 8ft, and the energy is cranking hard at 834 and 1012, but the wind is on it, making it look like a washing machine. This is definitely not for the faint of heart, and with sizes like that, it’s honestly only for the experienced crew. The beach setup is going to be a wrestling match, and honestly, it might be more interesting for the kite surfers than us paddle guys.
But then, hold on. Friday morning, the 21st of August. That’s the one. The wind drops right out to a light N cross-off, and the swell is still a solid 6ft from the WNW with a 10-second period. The energy is pumping at 597. This is the standout of the whole period. The conditions are finally aligning – clean, solid, and with enough power to make Tronoen work. It’s still a bit of a long-range call, so keep your fingers crossed, but that Friday morning is the one to circle on the calendar. The afternoon sees the onshore breeze kick back in, so it’s a morning mission for sure.
After that, the swell fades back down into the small stuff for the end of the window. It’s a long wait, but that Friday morning looks like it’ll be worth it.
Rusty, signing off.

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.
