The Lowdown
Alright folks, Rusty here. Let's look at what's on the table for the next couple of weeks at our spot, Tronoen. It’s a bit of a mixed bag, and we’ve got a slow start, so don’t rush to wax up just yet.
Right now and for the next couple of days, we’re in a bit of a lull. Things kick off on Friday the 11th with a cross-on breeze and messy, poor surf. By Saturday morning the 12th, the wind will go completely glassy, but don't get too excited – it’s only 3ft of weak, short-period swell (192 combined energy). It’s surfable, but far from a standout.
The real action starts to build Sunday morning the 13th. We’ve got a 5ft swell starting to show, with a period of 11 seconds and a clean offshore wind. The energy is moderate (631 combined energy). That’s the first real window of the period. By Monday morning the 14th, the swell drops back to 3ft but it’s clean with a cross-off breeze, and the wave comment says to expect good surf. That’s a nice little session if you’re keen for a wave.
A quick heads up for Wednesday the 16th: the swell jumps to 7ft with a moderate breeze creating clean conditions (618 combined energy). This is getting into expert-only territory with the size.
Now, we have some real promise further out. The first real standout arrives on Saturday the 19th. We’ve got 4ft of clean swell with a period of 11 seconds and a light cross-off breeze. The combined energy (419) is moderate, but the conditions are forecast to be good. That’s a solid session for intermediate surfers.
But if you can wait, the best offer of the whole outlook is on Wednesday the 23rd of September. Tronoen will be firing. We’re looking at a 6ft swell from the WNW with a very long 14-second period, channeling deep ocean energy. The wind is a light offshore breeze and the conditions are described as excellent for experienced surfers. The combined energy is a very strong 1196. This is a proper groundswell, and Tronoen is exposed, so it’ll handle it well. The water temperature is 65°, which is about normal for this time of year.
Tuesday the 24th morning is also worth a mention. The wind goes glassy again, with a 5ft WNW swell (500 combined energy). It will be clean and glassy – that’s a dream scenario.
Don’t get too excited about the last weekend. The energy drops off fast, and the wind turns nasty, so we’ll be back to poor conditions by Saturday the 26th.
Best Bet: If you’ve got the patience, hold out for Wednesday the 23rd. That WNW groundswell with offshore wind is the standout of the entire period. The Monday the 21st morning also looks very good with a 5ft offshore and clean. For a more relaxed paddle, Saturday the 19th morning is your safest bet for good, clean waves that won’t be too big for the average surfer.
Keep your eyes on the sky, the forecasts can always change.
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.
