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

G’day, Rusty here, and I’ve got a look at the surf for the next couple of weeks. We’re talking about Tsurigasaki Surfing Beach (Tokyo 2020) — the Olympic venue. The water temp’s sitting about average for this time of year, so nothing wild there.

Honestly, the first few days are a bit of a write-off. From Tuesday the 28th of July right through to the end of the month, we’re looking at tiny, weak waves. The swell’s barely pushing 1 ft to 3 ft, with combined energy way down in the low double digits (130 to 58), and the wind’s all over the shop — onshore, cross-off, or just meh. There’s a glimmer on Wednesday morning the 29th with glassy conditions and a 2 ft SE swell, but at 10-second period, it’s barely surfable. That’s a gap of a few days where you’d be better off checking the cams and staying patient.

Then Saturday the 1st of August rolls in with a tiny 1 ft swell and a long 17-second period in the afternoon, but the combined energy is only 157 — still weak, and the cross-shore wind isn’t doing it any favours.

Now, here’s where it gets interesting. Sunday the 2nd of August is the first real standout. Morning brings a 4 ft SE swell with a 14-second period, combined energy of 587 (moderate), and light cross-offshore winds. It’s clean, surfable, and the crowd factor is only “sometimes” here, so you might get a few waves to yourself. The afternoon holds up too, with 4 ft and 623 energy, just a touch more wind. That’s the best early call.

Monday the 3rd of August sees the swell jump to 6 ft in the morning, then 7 ft in the afternoon, both from the SE with a long 15-16 second period. Combined energy climbs to 1328 and 2224 — that’s strong wave energy. The morning wind is light cross-shore, but the afternoon gets a little choppy. Still, for intermediate surfers, this is solid. At 7 ft, it’s getting big, but not out of reach.

Tuesday the 4th of August is a step up: 10 ft in the morning, 12 ft in the afternoon, with a very long 18-second period. The combined energy is massive — 6061 in the morning, 9211 in the afternoon. But that’s where the caveat comes in: the wind is strong onshore (ENE to NE at 12-16 mph), and the afternoon is a write-off. This is expert territory only, and honestly, with the onshore wind, it’ll be a battle. Might be more for kite surfing than paddling.

Then Wednesday the 5th of August and Thursday the 6th of August get absolutely thumping — 18 ft to 20 ft SE swell, 18-second period, and combined energy up to 19,324. That’s extreme. But the JSON says it’s too big for this break, and the wind is fresh onshore or cross-onshore. Only for the most experienced, and even then, it’s dodgy. The forecast is less certain this far out, but it’s a big pattern.

The second week settles down. Friday the 7th of August drops to 15 ft, still messy, then Saturday the 8th down to 10 ft with cross-shore wind. By Sunday the 9th of August, we’re back to 4 ft to 5 ft ESE swell with 14-second period and light cross-onshore wind — more manageable, but not a standout. The rest of the second week (10th to 12th of August) is small, weak, and onshore, with combined energy dropping below 750. No real highlights there.

So, the best on offer is Sunday the 2nd of August for clean, fun waves, and Monday the 3rd of August for a bit more size. The big stuff mid-week is for experts only, and the second week is a letdown. Keep an eye on the forecasts, but for now, pencil in that Sunday.

Rusty.
