The Lowdown

Righto, grab a coffee and pull up a seat. Rusty here, and I’m staring down the barrel of the next couple of weeks at Tronoen. It’s a bit of a mixed bag, and if you’re looking to get wet, you’re gonna have to be patient. There’s a lot of onshore chop and crosswind ahead, but there is one solid little window that’ll make it all worth it.

The water’s sitting right around average for this time of year at 64°, so no surprises there. The issue early on is that while we’ve got some swell on the cards, the wind is just wrecking it. Tuesday the 1st kicks off with a small, weak 4ft pulse from the WNW and a weak energy reading (207), but the afternoon has a cross-onshore wind that turns it into a mess. Wednesday and Thursday are pretty much a write-off – tiny waves, onshore winds, and not much energy in the water (down in the 70’s to 125 range).

The first real standout comes on Saturday the 5th. We’re looking at a solid groundswell from the WNW pushing 5ft with a lovely 11-second period and a healthy 578 energy reading. The real beauty here is the morning: a clean, offshore wind from the east at just 6 mph. That’s going to be glassy, peeling, and clean as a whistle. This is the pick of the crop. Get there early because a break that’s exposed and handles a WNW swell this well will be a joy. The winds will switch onshore by the afternoon, so don’t sleep in.

After that, we hit another rough patch. Sunday the 6th and Monday the 7th have some size but the wind direction is all over the place – cross-off, then cross, then strong cross-on – keeping the surface ugly. The week from the 8th to the 14th is tough going. There’s some real punchy energy in the water on Wednesday the 9th (820 and even 1257 for the afternoon!), but it’s blowing 16 mph cross-onshore, so it’ll be a bumpy, blown-out mess. At that size with that wind, it’s honestly looking more interesting for the kite crew than a paddle surfer.

We get a little glimmer on Friday the 11th morning. A 6ft pulse from the west (8 sec period, energy of 432) and a cross-offshore wind from the NE at 9 mph. It’ll be clean, but the short period means it won’t have the same power as the Saturday 5th session. The morning of Saturday the 12th is similar – 6ft from the WNW with a longer 10-second period, cross-off wind, and 611 energy. That’s another clean option, but the short, punchy nature of the swell might make it a bit sectiony.

Looking way out into the second week, the morning of Wednesday the 16th is a promising long-range call. Clean offshore winds from the east at 16 mph and a 3ft swell from the WSW (energy 274). It’s not huge, but it’ll be clean and rideable.

Overall, don’t waste your energy on most of this run. Zero in on Saturday the 5th. That’s your day. Wind, swell, and energy all line up perfectly for a proper session. The rest? A lot of waiting.

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.
