The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Tronoen over the next couple of weeks.
First off, I gotta be straight with you – the start of this run is a total write-off. We’re looking at a solid gap of about seven days from now with absolutely no surf on offer. The conditions are just rubbish; cross-shore winds and lumpy chop are the story for the first week. So, don’t even bother waxing up until we get further into the period.
Now, the first real glimmer of hope shows up on Thursday, August 20th, in the morning. Tronoen will see a solid pulse of swell out of the WNW at 8ft, and the period is a nice long 11 seconds. That’s a proper groundswell. The combined energy is pumping at (1222) – that’s strong, powerful stuff. The wind is a light N breeze, so it’s blowing cross-offshore and keeping things clean. However, this is a big swell, over 8ft, so this is strictly for the experts. The tide or something else is questionable, so it’s a marginal call, but it’s the only window with any real size and clean conditions.
The water temp is sitting at 65°, which is bang on average for the time of year, so no need for a thick steamer.
The next sniff of a decent wave comes on Friday, August 21st, in the morning. The swell drops right back to 3ft from the NW, with a 9-second period. The combined energy is moderate (283). The wind is glassy, almost calm at 3 mph from the NNE, keeping it clean. The forecast is only “expect good surf conditions,” but it’s a small, clean morning. Crowds are “sometimes” a thing here, so you might have a few mates out, but nothing too hectic.
Honestly, looking at the whole 16 days, the only standout is that Thursday morning window. It’s big, powerful, and clean – but it’s a dangerous one for the experts only. The Friday morning is a nice little clean-up if you’ve got a log or a fish. The rest of the run is plagued by onshore winds and choppy, ugly conditions. It’s a tough stretch.
Stay patient, and keep an eye on the forecasts. Things can change quickly.
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.
