The Lowdown

Alright, mates, Rusty here. Let’s cut to the chase. The next couple of weeks are looking pretty flat and messy for the most part. We’ve got a lot of small, weak swell and the wind is rarely playing nice. There are a couple of brief windows where it might be worth a look, but don't get your hopes up too high.

Starting off at Tronoen on Sunday morning, the water is sitting at 65°F, which is pretty normal for this time of year. The surf is a weak 2ft from the northwest, but a 12 mph cross-shore wind is making it a complete mess. The energy is a weak 94, and it’s just not worth the effort. The afternoon is more of the same, just a bit more cross-on and choppy.

Monday morning brings a tiny bit of hope. The swell is still small at 2ft from the northwest, but the wind drops to a light 6 mph offshore. The energy picks up slightly to 105 and the conditions clean up. It’s surfable, but very ordinary. You’ll be scratching for anything. The afternoon is blown out again with a cross-on wind.

Tuesday and Wednesday are more of the same story. Small swells, poor winds, and not much energy. The wave heights stay under 4ft, but the wind states are all wrong. Tuesday morning has a clean 2ft from the northwest with a gentle offshore, but the energy is a weak 57. It’s glassy, but there’s just nothing to ride. Wednesday afternoon sees the swell bump up to 3ft, but the onshore wind ruins it.

Things get a little more interesting on Thursday the 13th. The swell pushes up to 4ft from the west, and the energy jumps to a moderate 290. But the wind is still cross-on from the northwest, keeping it choppy. There’s a bit more push in the water, but it’s not going to be clean.

The weekend rolls in with smaller, shorter-period leftovers. Sunday the 16th has a clean 3ft from the northwest with a light cross-off wind, but the period has dropped to a short 6 seconds. It’s going to be mushy and weak. The afternoon is bigger at 4ft, but the onshore wind kills it.

The only real standouts in this whole period are the mornings of Tuesday the 19th and Thursday the 20th. On Tuesday the 19th, we get a clean 2ft with a light offshore wind. It’s tiny, but it could be glassy. The energy is only 68, so don’t expect much. Thursday the 20th is the best of the bunch. The swell is 4ft from the west-northwest with a 10-second period, and the energy jumps to a solid 322. The wind is a light cross-off from the north-northeast, leaving the surf clean. The period is in that sweet spot, and while it’s not huge, it’s got the most power and the cleanest conditions of the entire forecast. This is your best bet for a real surf, but it’s a promise, not a guarantee, given how far out it is.

After that, the wind gets strong and the swell stays small. The last few days are a write-off with fresh breezes and lumpy conditions.

Honestly, there’s nothing here that’s going to get your heart racing. It’s a case of low expectations and grabbing whatever scraps the ocean gives you. Keep an eye on that Thursday the 20th morning, but don't book the day off work yet.

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.
