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

Alright, Rusty here. Let’s get into it.

Well, we’re looking at a fairly bleak start for Tsurigasaki Surfing Beach. The first few days are just not worth paddling out for. The swell is tiny, barely 1ft, with a short period that just doesn’t deliver any punch. The combined energy is weak, sitting at 43. It’s a real snoozefest. The water temp is sitting at 79°, which is pretty much bang on average for this time of year, so that’s one thing you don’t have to worry about.

Thursday morning, July 30, is the first chance to get wet, but with a 1ft swell from the SE and a period of 9 seconds, it’s just small, pretty ordinary stuff. The wind is a light cross-offshore from the SSW, which is a nice touch, but the waves just aren’t there. It’s clean but tiny. This stays the same through Friday, though the wind turns onshore, ruining the little bit of shape we had.

Saturday, August 1, isn’t any better. We get a long-period 16-second swell, but it’s only 1ft, so the energy is still weak. The wind is light and cross-on, so the wave faces are a bit messy. Still not worth the drive.

Now, Sunday, August 2, things start to get interesting. The swell jumps up to 4ft in the morning, with a 16-second period, and the combined energy climbs to 794. This is a proper groundswell, but it’s a bit of a double-edged sword. The period is very long, so at a beach break, these waves can get a bit too straight and crumbly. The wind is onshore from the ENE, making it choppy and uncertain. The afternoon stays similar, but with stronger wind.

Monday, August 3, the swell really starts to pump, hitting 8ft in the morning and 8ft in the afternoon. The period is 17 to 18 seconds, and the energy is massive, 3011 and 4437. But here’s the kicker: the wind is cranking from the NE, cross-on in the morning and onshore in the afternoon. It’s going to be a howling, choppy mess. This is too big for beginners, and even for intermediates, it’s going to be a battle. The setup is better for kite surfing than paddle surfing, honestly.

Tuesday, August 4, is even bigger. 10ft to 12ft swell. The energy is through the roof, 5345 to 6626. But the wind is still a problem. Strong cross-onshore winds make it lumpy and dangerous. This is for experts only, and even then, it’s not going to be pretty.

The best bet in the whole run comes on Wednesday, August 5, and Thursday, August 6. The swell is maxing out at 13ft to 15ft, with a 16 to 17-second period. The energy is insane, over 11,000. The wind is lighter, a gentle breeze from the ENE to E, but it’s still cross-on. The forecast notes say the wind and tide are favorable, but the swell is just too big for this break. So, unless you’re a big-wave charger with a lot of experience, this is a stay-on-the-beach day. The wave quality is poor because of the size and the cross-onshore wind.

After that, the size drops, but the wind stays a problem. Friday, August 7, has 8ft swell with a 14-second period, but the wind is cross-on, and there’s a risk of thunderstorms in the morning. Not ideal.

The next chance for something half-decent is Saturday, August 8, but it’s only 5ft to 5ft, with a 13-second period, and the wind is still cross-on. The energy is moderate at 1170, but the waves will be small and a bit messy.

From Sunday, August 9, onward, the swell stays in the 5ft to 8ft range, but the wind is consistently onshore or cross-on, mostly from the NE or ENE. The energy is moderate to strong, but the conditions are just not clean. The period drops to 10 seconds by the end, which is a shorter, weaker wind swell. It’s just not going to be a good time.

So, to be honest, there’s no standout day in this 16-day window. The two days with the biggest swell, August 5 and 6, are the most powerful, but they are too big and blown out for this spot. The first week is a write-off. The second week is just one long, onshore, messy slog. If you’re desperate, you could try the 5ft swell on August 8, but don’t expect much.

Rusty.
