The Lowdown

Right, folks, Rusty here. Let’s have a look at what’s coming.

Straight up, Tronoen is looking at a pretty bleak run for the next week and a half. The first solid surf of any real interest doesn't show until Wednesday the 12th of August. Before that, it’s essentially a write-off. From the 2nd right through to the 11th, we’re dealing with weak, messy, mostly cross-onshore junk. Swell heights barely nudge over 2 ft for the first week, with poor surf conditions day after day. The combined swell energy stays well below three figures—usually between 20 and 75—for most of that time, so honestly, don’t bother paddling out unless you’re desperate for a float.

The one small exception is a brief flicker on the morning of Wednesday the 12th. We get a little 4 ft swell from the WSW, combined energy of 270 (moderate), with a light offshore breeze from the ENE. The tide conditions and general setup might make it surfable, but it’s a short window. By the afternoon, the wind swings cross-onshore and chops it up again.

Then we see a bit more size building toward Sunday the 16th. A 7 ft to 7 ft swell from the WNW arrives with combined energy rising to 451–569, but the wind is cross-onshore and the surf looks messy. By Monday morning the 17th, it’s hitting 8 ft from the west, with energy cranked up to 1055. The wind is light cross-shore, so the waves could be powerful and hollow—but this is strictly for experienced surfers only. The period is short at 8 seconds, so it won’t be clean groundswell; it’s more of a wind-driven, powerful lump.

Water temperature is average for this time of year. Honestly, if you’re looking for one day to try, the morning of Wednesday the 12th is the best on offer, with clean 4 ft WSW swell and light offshore wind. It’s not a classic, but it’s something. The rest is a long wait.

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.
