The Lowdown

Hey folks, Rusty here. Let’s talk about what’s brewing for the next couple of weeks.

Honestly, the first part of the outlook is a bit of a bummer. We’re looking at a long dry spell stretching from now all the way to the morning of Friday, August 21st. That’s more than a week of near-zero action. The winds are mostly cross or cross-onshore, and the swell energy is weak to moderate, with readings mostly under 500. The waves are small, short-period, and generally chopped up. It’s a real test of patience.

The first real window of opportunity comes early on Friday, August 21st. Tronoen is the only spot worth looking at. The morning brings a light, clean cross-offshore breeze from the NNE, with a 4ft swell from the NW. The period is a short 9 seconds, so it’s not groundswell with heaps of power, but the wave energy is moderate at 245. The real win is those clean conditions – it’s a rare moment of quality. The water temperature is about average for this time of year, so nothing unusual there. Crowds are possible, so get in early if you can.

After that Friday morning window, the wind swings onshore and it’s right back to the poor stuff. The following weekend and into the start of the next week is a write-off – messy winds, small swell, and low energy.

Now, hold on to your boards, because things get interesting toward the end of the run. On Wednesday, August 26th, the morning session at Tronoen looks like a real standout. We’ve got a 5ft swell from the west-southwest with a solid 11-second period and moderate-strong energy at 595. The wind is glassy from the WSW – that’s as good as it gets for clean faces. This is a morning for experienced surfers to mark in the calendar.

And then, the real bomb drops on Saturday, August 29th. The morning shows an 8ft swell from the south-southwest, but with a short 7-second period, so it’s a bit of a lumpy, crumbly beast. The wind is light offshore from the NE, and the energy is strong at 707. This is expert territory – too big for beginners, and the short period could make it tricky.

The final note is for Sunday, August 30th. The morning brings a 10ft swell from the west-southwest, with a 9-second period and very strong energy of 1561. The wind is a clean cross-offshore from the NNE. The note says the swell is predicted to be too big for this break. This is a day for the experts only, and only if you’re feeling brave.

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.
