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

Alright, this is Rusty, and I’m checking out the surf for Tsurigasaki Surfing Beach (Tokyo 2020). Gotta level with you – there’s a big stretch of nothing, then a massive swell that ain’t really made for paddling.

Water temp is right around 78°, so nothing unusual for the season.

First real chance to get wet comes Sunday, July 26th, but it’s weak. A small 3ft swell from ENE with a short 7-second period, combined energy only (224) – real weak. Light east wind makes it rideable but marginal. After that, it’s a long, flat, poor spell all the way through the end of July and into early August. Days of tiny chop and onshore wind. Not worth it.

Come Monday, August 3rd, the swell wakes up. Morning brings 5ft from SE with a very long 15-second period (groundswell) and energy (1099). Afternoon it’s 6ft, same 15-second period, energy (1464). But the wind is onshore, and at a beach break, that long-period groundswell will be walling up and closing out. It’s building, but messy. Tuesday, August 4th, morning swell hits 8ft from SE, 16 seconds, energy (2608). Still onshore. Wednesday, August 5th morning, 8ft, 16 seconds, energy (3637) – that’s expert territory, and the onshore wind is ruining it. By afternoon, 10ft with 25 km/h onshore wind – total washout.

Then it gets wild. From Thursday, August 6th, the swell goes nuts – 12ft, 13ft, 15ft, and by Saturday, August 8th morning, it’s a massive 20ft from SSE with a 17-second period and energy (24472). That’s a monster. But the wind is blowing 35 km/h cross-onshore, lumpy and rough. The file says wind and tide are favorable, but that swell is way too big for this break – it’s a death slab for experts only, and the wind’s got it chopped. From the 6th through the 10th, this whole setup looks way more interesting for kite surfing than paddle surfing. The swell is too big, the period is too long for a beach break, and the wind is strong.

The only real standout? Maybe the morning of Monday, August 10th: 6ft from ESE, 14-second period, energy (3207), with a clean cross-offshore SSW breeze at 15 km/h. That’s your cleanest window across the whole 16 days, but it’s still a big, long-period swell for a beach break – you’ll need to work the currents. It’s the best of a tough forecast.

So yeah, first week is flat and poor, second week has serious size but onshore wind and stormy conditions. Not ideal, but that’s how it goes sometimes.

Rusty.
