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

Alright folks, Rusty here. Let’s have a look at the stretch ahead for the area.

Straight up, the outlook is a bit of a grind. The waves are coming in from a solid deep-water direction, but the wind is just cruel for most of the forecast. The water sits at 81°F, which is about average for this time of year, so at least you won't be freezing while you wait for a clean one.

We’re kicking off on Wednesday, the 5th of August. A big 12ft swell from the southeast is rolling in, with a very long period of 15 seconds, packing a strong wave energy (5405). But the wind is a moderate breeze from the northeast at 15 mph, blowing cross-onshore and choppy. It’s a mess. That’s a no-go for paddling, and honestly, with that much power and that wind, the setup looks more interesting for kite surfing than paddle surfing. The afternoon is just as bad with onshore wind.

Thursday the 6th and Friday the 7th see the swell drop a bit, hovering around 7ft to 6ft, still with decent 12-14 second periods. The wind eases up, but it’s still cross-onshore or cross-shore. The wave energy is moderate (around 1900-2200). The forecast calls it marginal, and I’d agree. It’s pretty choppy, not worth paddling out for unless you’re desperate.

Saturday the 8th is a little smaller at 5ft, with a 13-second period for decent shape. The wind is light at 9 mph, but it’s still cross-onshore, keeping things choppy. It’s not terrible, but it’s not good.

Sunday the 9th, the morning shows a 6ft swell from the east-southeast, with the wind turning onshore from the northeast at 9 mph. The afternoon gets worse with the wind picking up to 15 mph. That’s a write-off.

The middle of the week, from Monday the 10th through to Wednesday the 12th, is a write-off. The wind is howling from the north-northeast between 22 and 25 mph, with fresh to strong breeze conditions. The swell is all over the place, from 6ft up to 12ft again, but it’s all lumpy, cross-onshore garbage. The wave energy is moderate to strong (up to 5156), but it’s unsurfable.

Finally, Thursday the 13th of August offers a little glimmer. The wind swings west-northwest at 22 mph in the morning, turning cross-offshore, and the water is clean. The swell is tiny at 4ft, with an 11-second period, and the wave energy is weak (282). The afternoon looks even cleaner with a south wind at 12 mph, cross-offshore, and the swell dropping to 3ft. It’s small, but it’s the cleanest window we’ve seen. If you’ve got a longboard, this might be your only chance for a couple of clean, small waves.

From Friday the 14th right through to the end of the outlook on Thursday the 20th, it’s all small and small-to-marginal surf. The swell stays between 3ft and 7ft, with periods dropping to 8-10 seconds, meaning weaker, shorter-period windswell. The wind is mostly onshore or cross-onshore, keeping things choppy or messy. There are no standouts in the second week. The wave energy is all weak (under 1000). It’s a long, flat run of poor conditions.

The only real standout in this whole 16-day window is the clean, cross-offshore window on Thursday the 13th. The swell is tiny, but the wind is right. If you want to get wet, that’s the day.

Rusty.
