The Lowdown

Righto, grab a coffee and settle in, ‘cause I’ve got the full picture for Tronoen. We’ve got a solid run of swell coming through, but the wind is gonna be the real story here. The window kicks off this Saturday morning, September 5th, and it’s a bit of a tease.

The Outlook

Saturday morning, September 5th, is the standout, no question. We’ve got a decent 7ft swell rolling in from the WNW, with a solid 13-second period. That’s proper groundswell with some real grunt behind it – the combined energy is sitting at 1383 (moderate to strong). The water temp is 65°, which is pretty normal for this time of year, so no nasty surprises there. What makes it special is the 6 mph offshore breeze straight out of the ENE. That’s going to keep it clean, with nice lines. This is a spot for the experienced crew, though – at 7ft, it’s a bit hefty for the beginners. The crowd factor is “sometimes,” so you might have a few mates out, but nothing crazy.

Now, that’s the peak. By Saturday afternoon, the wind swings to a cross-on from the SSW, and the swell drops a touch. It’s still surfable, but the magic is gone.

Sunday, September 6th, starts with a 4ft swell and a cross-off breeze from the ESE, which is actually clean. The period drops to 10 seconds, so it’s less punchy, and the energy is way down at 226 (weak). It’s a marginal call at best, and the score reflects that. The afternoon just gets worse.

Then we hit a pretty grim stretch. From Monday, September 7th, all the way through to about Thursday, September 17th, the wind is either onshore, cross-on, or just plain strong. The swell sticks around, often between 5ft and 7ft, and the period is decent, but it’s all blown out. The combined energy values are often in the three-digit range (moderate), but it’s messy, choppy, and the scores are low. It’s not worth paddling out for. There’s a brief moment on Monday, September 14th, during the afternoon, with a glassy 2ft wave, but it’s tiny and weak – the energy is just 88 (weak). Not really a goer.

The real kicker is that the best conditions are all in the first weekend. After that, it’s a long wait. The swell direction (WNW) is bang on for Tronoen’s optimum (WSW), but the wind just won’t play ball. The only real saving grace is that the spot is fairly consistent, so it’s not a total dead zone, but the forecast is what it is. For a surfer, this is a one-morning-wonder, then a whole lot of nothing worth chasing.

Stay safe out there.

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.
