Tronoen Surf Forecast and Surf Report

Alright, Rusty here, let’s talk about what’s lined up for the next stretch.

Right off the bat, I gotta be straight with you—this 16-day window is a tough one for Tronoen. We’ve got a long, dry spell of poor conditions before anything even remotely worth paddling out for shows up. The first real glimmer of hope isn’t until Wednesday, August 12, and even then it’s only just surfable.

The water temperature is sitting at 64°, which is about 0.9° below the norm for this time of year—nothing wild, just a little cool for the season.

So, here’s how it shakes out. Monday the 10th and Tuesday the 11th are write-offs: small swell, messy wind, and choppy water. Keep the board in the car. Wednesday morning, August 12, we finally see a slight pulse of 3ft swell from the west with a 10-second period and a clean cross-offshore breeze. The combined energy is moderate at 128, and it’s surfable, but it’s ordinary. Still, that’s the best you’ll get for a few days.

Thursday the 13th and Friday the 14th see a bit more size—4ft on Thursday morning—but the wind is all over the place, cross or cross-on, and the chop is ugly. Not worth it.

Saturday morning, August 15, the swell bumps up to 4ft from the northwest with a clean cross-off breeze and a combined energy of 196. That’s the first real standout of the whole period. The waves are weak period at 8 seconds, so not a lot of push, but the clean conditions make it rideable. You’ll have company though—crowds are sometimes a problem here.

After that, it drops off again into small, weak, and choppy stuff through the middle of the next week. The next real highlight doesn’t come until Wednesday, August 19, in the morning. Swell is 3ft from the west-northwest, but the period jumps to 11 seconds—proper groundswell energy. Combined energy is a solid 244. The wind is light and cross-off, so it’ll be clean. The only issue? It’s marginal, with a score that suggests questionable tide conditions. Still, if you time it right, it’s the best-looking session in the second week.

Then we get a real wildcard on Sunday, August 23. The morning brings a big 8ft swell from the west-northwest, with a 10-second period and a massive combined energy of 1391. That’s a lot of power. But the wind is a fresh cross-shore from the north-northwest at 19 mph, making it lumpy and choppy. That’s expert-only territory, and honestly, it’s more of a kite-surfing setup than a clean paddle session. The afternoon is the same story—big, messy, and not for the faint of heart.

The very end of the window, Tuesday August 25, has a 2ft swell from the west with a 16-second period—very long period groundswell. Energy is 315. But the wind is light cross-on, and the report calls it marginal. For a point break or reef, that long period could be magic, but here at Tronoen, it’s likely to close out or be too straight. Something to keep an eye on, but not a lock.

Overall, the best on offer is Saturday morning, August 15, for the cleanest conditions and a bit of size, and Wednesday morning, August 19, for the better quality groundswell if you can work around the tide. Everything else is a battle.

Rusty.
