The Lowdown
Alright folks, Rusty here. Let's talk about what's cookin' at Tronoen.
Right off the bat, we’ve got a pretty bleak stretch. The water’s sitting at 66° – that’s about average for this time of year. The first few days are looking pretty rough, with weak energy and onshore winds making a mess of things. It’s not until the end of next week that we start seeing some real potential.
Sunday the 6th is a write-off, with a weak 4ft swell and cross-off wind that isn’t really doing us any favors. The energy is a paltry 226, so don't expect much. Monday the 7th shows a jump in size, with a 6ft to 6ft groundswell from the W, but the wind is straight onshore and the wave state is described as "unknown," so it's likely a washout. The energy picks up to 1133-1169, which is moderate, but the quality just isn't there.
The whole of the following week, from Tuesday the 8th through to Saturday the 12th, is a poor run. Onshore winds, cross-onshore winds, and choppy conditions dominate. Energy levels fluctuate, but the wind keeps ruining it. The standout opportunity arrives on Saturday the 19th of September. The morning brings a clean 6ft swell from the WNW with a cross-off wind from the NNE. The energy is a solid 616. This is the pick of the bunch for the whole forecast period. It’s clean, it’s got push, and it’s well-shaped for Tronoen. But keep in mind, it is a long-range call, so keep an eye on it.
Sunday the 20th afternoon is another cracker, with clean conditions and a 6ft WNW groundswell with a light cross-off wind from the SE and 784 energy. The period is 12 seconds, so a nice, long groundswell that will wrap in nicely here.
Monday the 21st has a clean morning but the energy drops off, so it’s not as exciting. For the first week, the pick is basically non-existent due to wind. The second week, from the 18th onward, shows some hope, but the wind is still a major factor. The 18th is a write-off again.
Standout: The morning of Saturday, 19th September is your best bet. Clean, chest-to-head high swell with clean cross-off wind. It’s a classic Tronoen session. The afternoon of Sunday, 20th September is a very close second, with even lighter wind.
Rusty out.

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.
