The Lowdown

G'day, I'm Rusty, and I've got the gen on Tronoen for the next couple of weeks. Right off the bat, it's a pretty full-on start, but we've got a proper window of opportunity if you're patient.

The water temp here is sitting right on the money at 65°, which is totally normal for this time of year. No surprises there.

Alright, let's get into it. The next few days are a write-off, honestly. We're looking at a solid 7ft to 8ft of messy, short-period swell, but the wind is howling onshore or cross-onshore, and the wave energy is moderate to strong (481 to 1409). The surf is just poor. Monday the 1st of September teases a bit with a 5ft WNW swell and a 9-second period, but it's cross-shore and only a marginal call. Same goes for the rest of the first week—nothing but onshore junk and tiny waves. It's a grim start.

Then we get a glimmer. Friday the 4th of September has a 6ft swell from the WNW with a longer 12-second period, packing a solid punch of energy (851), but it's still cross-onshore and choppy. Not great.

But hold on. Saturday morning, the 5th of September, is where it's at. We've got a clean 6ft groundswell from the WNW, a proper 11-second period, and a light cross-offshore breeze from the north. The energy is strong (764), and the forecast is calling for "very good surf conditions." This is the standout. Tronoen is exposed and handles a WSW swell best, so that W to WNW direction is a good match. The waves will be a solid size for intermediates, but at 6ft, beginners might find it a bit much.

Sunday morning the 6th cleans up with a cross-offshore breeze again, but the swell has dropped to 4ft. It's a marginal call, but still clean. After that, the surf fades away into a tiny, choppy mess for the middle of the week.

We've got a big gap with hardly anything until the 12th of September, Saturday morning. That's a full week of average to poor conditions. But on Saturday the 12th, a 4ft swell from the west with a 9-second period rolls in, and the wind goes light offshore from the east. The energy is moderate (207), and it's clean. It's a good option, but not a classic.

Then Sunday the 13th of September morning is another one to circle. A 5ft swell from the WSW, 8-second period, with a light offshore breeze from the east. The energy is moderate (260), and the conditions are clean. Again, 5ft is a nice size for a lot of surfers, but not a beginner wave.

The outlook after that peters out into onshore junk again. So, to sum it up: the one real standout is Saturday morning, the 5th of September. Get on it. The following weekend, the 12th and 13th, has clean but smaller waves. The rest is a write-off.

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.
