The Lowdown
Hey, Rusty here. Let’s run through the outlook at Tronoen.
The next couple of weeks look pretty flat and messy overall. There are only a few windows where you can even get wet, and the wind is usually the problem.
The first chance is Wednesday morning, 12 August. Swell is tiny at 3ft from the west, with a 10-second period. The combined energy is weak (125). It’s clear skies, with a light cross-offshore breeze from the SE at 9 mph, so the water is clean. The water temp is 65°, which is about average for this time of year. It’s surfable, but just barely—a little knee-high wave.
Later that day, the wind turns onshore from the west at 13 mph, and it’s game over.
Thursday 13 August morning sees a little more size—4ft from the west, 11-second period, combined energy moderate (344). But the wind is a cross-shore from the NW at 13 mph, making it lumpy and poor.
Friday 14 August and Saturday 15 August are similar—small waves, but the wind is either cross or cross-onshore, often fresh. Saturday morning is clean with a cross-offshore breeze from the north at 13 mph, but the swell is a weak 4ft from the WNW with a short 8-second period. Still poor.
Sunday 16 August brings 5ft from the NW, but the period drops to 6-7 seconds, and the wind is a mess. The combined energy is moderate (234). That’s too big for beginners, and the short period means it’s just bumpy windswell. The morning is clean with a cross-offshore breeze, but the waves are lumpy.
Monday 17 August morning is the best of the first week—3ft from the NW, 6-second period, combined energy weak (62). The wind is light cross-offshore from the north at 9 mph, so it’s clean. But again, tiny and weak.
From Monday afternoon onward, it’s a long stretch of poor surf. The swell stays small—mostly 1ft to 3ft—and the wind is nearly always onshore or cross-shore, often fresh to strong. There’s one brief highlight on Thursday 20 August morning: 4ft from the NW, with a light cross-offshore breeze from the NNE at 9 mph, giving clean conditions. The combined energy is moderate (151) and the period is 8 seconds. It’s the only half-decent window in the second week.
The two best moments are Wednesday morning 12 August for the cleanest conditions, and Thursday 20 August morning for a slightly bigger wave. Neither is a true standout—it’s just the least bad of a poor run.
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.
