Tsurigasaki Surfing Beach (Tokyo 2020) Surf Forecast and Surf Report

Alright, folks. Rusty here.

Honestly, looking at the whole run, it’s a bit of a waiting game.

We start off on Thursday the 30th of July with tiny, glassy waves at Tsurigasaki Surfing Beach. Swell is a knee-high 1 ft from the SE, and the combined energy is weak (43). The water is sitting at 79°, which is about average for this time of year. It’s surfable, but very ordinary.

Friday and Saturday look pretty poor. The wind swings onshore and the tiny swell gets even messier. Not worth paddling for.

There’s a little spike of hope on Sunday the 2nd of August. The morning shows a building SE swell of 4 ft with a very long period of 16 seconds. That’s genuine groundswell energy, and the combined energy jumps to a moderate 650. The wind is offshore from the ENE, which is a major positive. This is actually a standout window. The long-period swell will love the river mouth setup here for some lined-up walls. Be aware, though, this spot can get crowded. The afternoon gets ruined by strong onshore winds from the NE, so you want to be on it early.

Then things go wild. From Monday the 3rd through to Wednesday the 5th of August, the swell really jacks up. We’re talking 7 ft to 15 ft from the SE, with combined energy skyrocketing into the thousands (2790 up to 10357). That is very strong wave energy. However, the wind is howling from the NE, mostly cross-onshore. This creates a messy, choppy, lumpy mess. At these sizes, this is strictly for experts, but the conditions will be horrible for a surfboard. Honestly, with this much wind and size on a beach break, it looks more interesting for kite surfing than paddle surfing. The afternoon of Wednesday the 5th has the wind turning onshore, but the swell is predicted to be too big for this break anyway.

The swell stays big, in the 8 ft to 13 ft range, right through to Friday the 7th, but the wind stays ugly. There’s a massive gap of poor conditions from Sunday the 2nd afternoon all the way until the next real window.

After a run of poor and marginal days, we finally get a solid window on the morning of Sunday the 9th of August. The swell has dropped to a manageable 5 ft from the ESE, with a solid 13-second period and a combined energy of 932. The wind is offshore from the ENE, which is a major positive and will deliver some glassy, clean faces.

And then, the real standout is Thursday the 13th of August morning. Wait, hang on... looking closer, the 13th has a big onshore wind. Scratch that. The best on offer in the second week is actually the morning of Sunday the 9th of August. That 5 ft ESE swell with offshore ENE wind is your clear winner. It’s not massive, but it’ll be clean, well-shaped, and a proper session. Everything after that gets blown out again by fresh cross-onshore winds.

So, to sum it up: for the near term, be on the water for the dawn patrol on Sunday the 2nd of August for a clean, long-period groundswell. For the long run, Sunday the 9th of August morning looks like the best bet with that clean, offshore swell. The rest you can sleep in.

Rusty.
