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

Alright, this is Rusty. Let's get into it.

Right now, Tsurigasaki Surfing Beach has got a bit of a tough run ahead. The water temp is sitting right around average for this time of year at 79°, so that’s not the story here. The story is the wind and the swell timing. We’ve got a decent pulse of groundswell heading our way, but the conditions are going to make it a real challenge to get a good one.

Looking at this Friday morning, we’re starting off small with some weak 1ft SE swell and a cross-onshore breeze. It’s not worth paddling out for. Friday afternoon is pretty much the same story.

Now, Saturday the 1st of August is a bit of a tease. The morning goes glassy with a light, knee-high SE swell. The combined wave energy is weak (43) but the glassy conditions mean it’s surfable, just very ordinary. If you’re desperate for a slide, that’s your window, but don't expect much. The period is a long 11 seconds, which is good for shape, but there’s just not enough size to get excited about.

The real action starts Sunday the 2nd of August. We get a jump in size. Sunday morning sees a 4ft SE groundswell with a very long 16-second period. The wave energy jumps right up into the moderate range (612), which is promising. The wind is light onshore from the ENE. It’s a bit of a gamble at a beach break with that period—it might fatten up—but the potential is there for some clean, lined-up walls if the tide plays ball. This is probably the pick of the first week. Sunday afternoon gets messy with a stronger onshore breeze, so don't sleep on that morning session.

Monday the 3rd and Tuesday the 4th see the swell pumping up big time. We’re looking at 7ft to 12ft of SE swell. This is big, powerful stuff with combined energy readings shooting into the thousands. That's a lot of water moving. However, the wind is hammering onshore or cross-onshore from the NNE and NE at 15 mph. For a beach break like this, that’s going to be a washing machine. This is for expert chargers only, and even then, it’ll be ugly. It’s honestly going to be a more interesting setup for the kite surfers than for paddle surfing.

The huge swell peaks around Wednesday the 5th of August through to Thursday the 6th, with waves hitting 13ft to 15ft from the SSE with a 16 to 17-second period. The combined energy is enormous, over 10,000 on Thursday morning. But the wind is still a problem—cross-onshore. It’s predicted to be too big for this break anyway. There’s a marginal window on Wednesday afternoon and Thursday afternoon where the ratings are a bit better, but the combination of size and wind is a major caveat for anyone but the most experienced.

From Friday the 7th of August, the swell drops back into the 4ft to 5ft range for a while. The winds are still mostly onshore or cross-onshore from the ENE, NE, and even a strong breeze from the NNE later on. That’s going to keep things pretty choppy and messy through the second week.

Honestly, looking at the whole 16-day window, there's only one standout that's worth getting excited about. You want to be on the water Sunday morning, August 2nd. That 4ft SE swell with the long period and light onshore wind is your best bet for a fun, clean session before everything gets blown out or just too big and raw. After that, it’s a long wait of chopped-up, messy conditions. The forecast can always change for the better, but as it sits right now, Sunday morning is the one to lock in.
