The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it—this is a rough patch for Tronoen. The 16-day outlook starting Saturday the 15th of August is almost a total wipeout. From the 15th right through to Friday the 28th of August, we’re looking at nearly two weeks with no decent surf. The wind is mostly cross or cross-onshore, and the swell keeps coming from the WNW, which isn’t the direction this spot likes—it wants a good WSW. Every day is poor, choppy, and messy.
The water temp is about 67°F with an anomaly of 1°F—right around average for the season.
The only real glimmers are right at the tail end. On Saturday morning the 29th of August, we get a light cross-offshore breeze and a 3ft WNW swell, period 9 seconds, with moderate energy. It’s called “surfable but very ordinary.” Not a standout, but it’s as good as it gets. Then Sunday morning the 30th of August, another clean moment with a light offshore and a 2ft NW swell, but the period is short at 8 seconds and the energy is weak.
If you’re into kite surfing, the cross-shore winds and lumpy stuff earlier might be worth a look. For paddling? It’s a long, quiet spell. But hey, forecasts change—don’t lose hope.

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.
