The Lowdown

Righto, grab a coffee, let’s talk about what’s shaping up at Tronoen. This spot’s got a bit of a split personality over the next couple of weeks – some solid, clean windows, but plenty of messy wind and sketchy conditions to work around.

We kick off on Wednesday the 16th with a solid 8ft swell out of the WNW, but it’s a write-off – cross-shore winds are up around 12-16 mph and the wave comment says it all: marginal at best. That theme carries into Thursday and Friday, where onshore winds and rain keep things ugly. Friday morning actually has a decent-sized 8ft swell (WNW, 13-second period) and the combined energy reading is pumping at 2149, but it’s got a cross-on breeze and the forecast flags it as marginal due to tide. Not worth paddling out for.

The first real glimmer comes on Sunday the 20th of September. Early morning we’ve got clean conditions – a light 3 mph northerly breeze, almost glassy – with 6ft of WNW swell and a combined energy of 647. That’s a nice, clean, intermediate-friendly wave. The wind is cross-off, so faces should hold up well. Sunday afternoon though, the chop returns.

Monday the 21st is the true standout of the first week. Morning session is a beauty: 5ft swell from the WNW with an 11-second period, and a gentle offshore breeze from the ENE at 9 mph. The wave comment says “expect very good surf conditions” and the combined energy sits at 504 – moderate, but clean as a whistle. Water temp is about average for the time of year. Crowds can be around sometimes, so get in early.

We get another solid run on Thursday the 24th – morning brings clean conditions with a light NNE breeze and 4ft of WSW swell (12-second period). Then Friday the 25th morning is another cracker: 6ft swell, 11-second period, and a clean offshore ENE breeze at 9 mph. That’s a repeat of Monday’s quality – very good conditions.

The second week gets quieter. Saturday the 27th of September early is a special one though – glassy conditions, light easterly breeze, 4ft of long-period W swell at 14 seconds, and combined energy of 658. That’s a proper groundswell with shape, best caught on the point or reef rather than hammering a beach break. Expect some long lulls but clean, lined-up sets. A true morning gem.

After that, the wind turns ugly again – strong breezes and lumpy chop through Monday the 28th and Tuesday the 29th, with onshore winds up to 25 mph. Swell drops away and the energy readings fall below 300. Not worth it. By Wednesday the 30th and into October, it’s messy cross-shore junk at best. Beginners should steer clear of anything over 5ft, but honestly, after the 27th there’s nothing beginner-friendly until the forecast changes.

So, the takeaway? Sunday the 20th morning and Monday the 21st morning are your first-week standouts. Saturday the 27th morning is the sleeper hit of the second week – glassy, long-period, and clean. Don’t sleep on it.

Stay stoked,
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.
