The Lowdown

Hey, it's Rusty. Let’s break down the next few weeks at Tsurigasaki Surfing Beach, the Olympic spot. The water’s running about 77°F, which feels a bit colder than average for this time of year—nothing crazy, but you’ll notice it.

First few days are pretty sluggish. Thursday the 6th and Friday the 7th have chest-to-head high swell around 5 to 7 feet from the SSE, with moderate to strong wave energy (1955). But the wind is either onshore or cross, so the waves are choppy and marginal. Not worth your time.

Saturday the 8th and Sunday the 9th are similar, with the swell dropping to 4 to 6 feet, and the wind still messy. Energy backs off (721 to 1074). Still not clean.

Monday the 10th is a total loss—strong 35 km/h winds from the NNE, lumpy, poor. Stay on the beach.

Now for the real deal: Tuesday, August 11th, morning. This is the standout. A solid 10-foot swell from the ENE, strong energy (2261), with a 11-second period—proper groundswell. The wind is light cross-offshore from the WNW, which means clean, glassy waves. The report says it’s excellent for experienced surfers, and at 10 feet, this is expert-only territory. Crowds are possible, so get there early. The afternoon turns cross-on, so the morning is your only window.

From the 12th onward, it’s a slow fade. Wednesday the 12th has 8 to 10 feet but the wind is howling at 35 km/h from the north, making it lumpy and ugly. Thursday the 13th has a cleaner cross-off wind but smaller 7 to 7 foot swell—still marginal, but the afternoon might offer a clean-ish wave.

Friday the 14th through the rest of the outlook is mostly poor. Winds stay onshore or cross-on, swell drops below 6 feet after the 15th, and the energy fades to weak (361 to 552). From the 16th onward, it’s all poor conditions with onshore winds and small, weak surf. Not worth paddling out.

After the 11th, there’s a long, dry gap of about a week and a half with no real quality. This spot isn’t the most consistent, and this run proves it.

So: if you’re experienced, hit Tuesday morning, August 11th. That’s your best bet. Otherwise, sit tight and wait for the next system.

Rusty.
