The Lowdown

Alright folks, this is Rusty. Let's have a look at what's on the menu for us.

Right off the bat, I gotta be straight with you: the next week and a half is a real struggle. We've got a long gap of pretty ordinary conditions, nothing really worth paddling out for until we get into the second week. The first real glimmer of hope appears around the morning of August 11th. That's a Tuesday, so mark it. Before that, you're looking at small, weak, messy stuff. The combined swell energy is weak, mostly under 100 (88), and onshore winds just ruin it. A few mornings have clean conditions, like the 1st and 2nd, but the swell is tiny, around 1ft to 2ft, so it's barely a ripple.

Now, let's talk about the one standout. The morning of August 11th is your best bet. Tronoen is picking up a clean 4ft swell from the west with a decent 8-second period. The real winner here is the wind: a light breeze from the southeast, which is cross-offshore. That means clean, peeling lines. The combined energy is a moderate 259, so there's some push behind it. This is a fairly consistent spot, so you should get some waves. It's not massive, but it'll be the best quality we see in the whole window.

The water temperature is about average for this time of year, nothing weird to report.

After that, we get a bit of a mix. The morning of August 12th at Tronoen might be worth a look, with a glassy 3ft swell from the WSW. It's small, but glassy conditions are a major positive. The combined energy is moderate at 177. It's a bit inconsistent, but if you're keen for a longboard and don't want crowds, it could be a good session.

The rest of the window into the second week fades out again, with small swell and onshore winds returning. The combined energy drops back to weak numbers (48, 30). Overall, it's a pretty bleak outlook for the next 16 days. The one bright spot is that Tuesday, August 11th morning. Don't sleep on it.

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.
