The Lowdown
Alright, let’s have a look at what’s shaping up for Tronoen. It’s a fairly consistent intermediate spot, exposed to the open ocean, and it likes that swell from the WSW. But honestly, the next week and a half looks pretty rough. There’s a big gap of almost no surf worth bothering with right from the start, lasting through until the morning of Saturday the 15th of August. That’s a long stretch of blown-out, weak, and messy conditions.
For the first few days, the wind is just wrong – strong cross-onshore and onshore, making a mess of even the small swell that’s around. The combined energy is weak, often under 100 or just over 200 (202-207), with short periods around 7-8 seconds. It’s just not going to be any fun. Thursday the 6th has a bit of a cross-off breeze in the morning, but the swell is tiny at 1 ft and the energy is a paltry 52. Not worth the paddle.
We finally see a glimmer of hope on the morning of Saturday the 15th of August. The wind is light and offshore from the ENE, and the swell is a clean 4 ft from the WNW with a period of 9 seconds. The combined energy hits 244 (moderate) and the conditions are clean. That’s the standout in this whole 16-day window. The 4 ft is a fun size, not too big, and with that offshore wind, Tronoen should be offering up some nice, shapely waves. It’s the best on offer by a long shot.
Sunday the 16th keeps the size at 5 ft from the WNW, but the wind is a cross-off from the ESE, so it’s still clean on the morning. The energy is a bit stronger at 256. But the real gem is the morning of Monday the 17th of August. The swell is 5 ft from the WNW, period 8 seconds, and the wind is light offshore from the NE. The combined energy is 270 (moderate). It’s clean, and it’s the second best window. The water temperature is about average for this time of year, so no surprises there.
Don’t get your hopes up for the afternoons – the wind shifts onshore and ruins it. The 5 ft swell on Monday afternoon looks like it’s going to be a lumpy, choppy mess. So, your two real windows are the mornings of the 15th and the 17th of August. The 15th is the best bet. The 17th is a close second, but it’s a bit bigger and more powerful, so it might be a bit more of a handful. After that, the forecast gets messy again.
So, if you can wait, the 15th of August is your day. Get out there early.

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.
