The Lowdown

Alright, surfers, let’s take a look at what’s coming down the pipeline here for Tronoen. The next couple of weeks have got a bit of a slow burn to them, but there’s a real corker of a session shaping up towards the end if you can wait it out.

For the first few days, it’s a bit of a struggle. Thursday the 10th is a write-off – we’ve got poor surf conditions with a weak, short-period swell and some cross-onshore breeze messing things up. Not worth paddling out. Friday the 11th isn’t much better either; the swell bumps up a bit to 1.5m from the west, but it’s still a marginal affair with questionable tide and wind.

Then we start to see some life on Saturday morning the 12th. The wind goes glassy, and we get clean 1.0m waves from the west, with moderate wave energy (211). That’s your first real window. It’s small, but it’ll be clean and fun for an intermediate.

Sunday the 13th sees a bigger pulse of swell – 1.7m from the west-northwest with a longer 11-second period and strong wave energy (718). But the wind is cross-onshore, which messes the surface up. The morning window might still be okay if you’re keen, but it’s not a standout.

Monday the 14th morning cleans right up. The wind turns cross-offshore from the ESE, and the 0.9m west swell gets clean. It’s not big, but the quality is there for a quiet session. After that, Tuesday and Wednesday are either too windy or too messy to get excited about, though Wednesday the 16th does see a bigger pulse – 2.0m from the WNW with very strong wave energy (1535) – but it’s still got a cross-off wind and is more for the experienced lot on the bigger side.

Now, if you’ve got patience, Saturday the 20th is the one to circle. Early morning we get a massive 3.0m west-northwest swell with a very long 16-second period – that’s proper groundswell. The wave energy is massive (5582) and the wind is offshore from the ENE. But here’s the thing: this is too big for most, even for the confident intermediate. It’s a clean, powerful beast that’ll only suit experts. The afternoon stays big too at 3.5m, so if you’re not a pro, stay safe and watch.

But the real sweet spot? That’s Monday morning the 21st. The swell drops to a still-sizable 2.2m from the WNW with a long 12-second period. The wave energy is still strong (1332). And here’s the kicker – it’s glassy. Dead flat, offshore calm. This is excellent surf for experienced surfers. Crowds are possible here, so get in early. The wave direction (WNW) matches what Tronoen wants (WSW optimum, so close enough), and the quality is top-tier. That’s your standout, right there.

After that, the rest of the outlook tails off. Tuesday the 22nd morning is clean with a smaller 1.1m, and Thursday the 24th afternoon has some clean 1.2m waves, but nothing special. The final Friday the 25th is just too small and windy to bother.

So, to sum it up: the first week is a slow grind with a few clean but small windows. The real pay-off is the weekend of the 20th–21st, especially Monday morning the 21st with glassy, clean, 2.2m groundswell. That’s the session.

Stay stoked.

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.
