The Lowdown

Alright, this is Rusty, checking in from Tronoen. Let's get into it.

Honestly, looking at the full 16-day window, we’ve got a long wait for anything decent. The first week and a half are pretty much a write-off, with a lot of small, wind-affected slop. There’s a real gap in quality surf until the tail end of the period.

The action starts on Sunday, August 9th morning. The swell is a tiny 3 ft out of the NW, but the wind is light and offshore from the E, keeping things clean. The combined energy is weak (98). The water temp is about average for the time of year at 64°F. It’s surfable, but really ordinary.

The same goes for the mornings of Tuesday, August 11th and Wednesday, August 12th. We’re looking at tiny, clean waves. Tuesday morning has a glassy 2 ft NW swell, and Wednesday morning is a glassy 1.0 ft W swell. The energy is gone – 48 and 23 respectively. These are barely worth a paddle.

As we move towards the end of the second week, things start to look more promising. The standout of the whole forecast is Monday, August 17th morning. The wind is glassy from the NE, and we’ve got a clean 4 ft swell from the WNW. The combined energy is solid (283), and the conditions are reported as "good". This is your best bet for a proper session.

But the real highlight to keep an eye on, and this is a long-range one so it’s promising but less certain, is Wednesday, August 19th morning. The forecast shows a 7 ft swell from the WNW, with glassy conditions again. The combined energy jumps to 643, which is significant. That’s a lot of power. For an intermediate spot, this is going to be a solid, punchy groundswell. At 7 ft, it’s getting into the territory where it’s more for experienced surfers. It’s a true standout in an otherwise bleak forecast.

Outside of that Monday and Wednesday morning window, the winds are generally onshore or cross-shore, ruining the shape. The swell direction is mostly from the NW or W, which is a good match for the spot’s optimum WSW direction, but the wind just kills it.

So, to wrap it up: the first ten days are pretty grim. If you want to get wet, target the morning of Monday, August 17th. The heaviest, most powerful swell arrives on the morning of Wednesday, August 19th, but it’s a long way out. Keep your fingers crossed the wind holds.

Rusty out.

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.
