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

Alright folks, Rusty here. Let’s have a look at what’s coming up for Tsurigasaki Surfing Beach (Tokyo 2020). The next week and a half is a real mixed bag, with a lot of small, grovelly days and onshore wind to wade through before we get a promising window of proper swell. It’s a waiting game.

First thing’s first, the water temp is sitting at 75°, which is about 2° cooler than the usual for this time of year. Nothing crazy, just a touch on the fresh side, but not enough to worry about without a spring suit at this time of year.

We kick off the period on Sunday the 12th with pretty poor conditions. Just 2ft of swell from the east, weak energy (66), and a cross-off wind making it a bit messy. Not worth paddling out for.

Monday the 13th is a bit of a tease. Morning glass-off with a light NNW breeze, and the swell bumps up to 3ft from the south, but the period is a short 6 seconds, so it’s weak and won’t have any push. The afternoon improves with a clean offshore wind from the WSW, but the swell drops to 3ft. It’s surfable, but really ordinary stuff.

Tuesday the 14th is tiny in the morning with 1ft and glassy conditions, but it’s a long-period 12-second swell from the SE – that’s a groundswell, but so small it’s almost flat. There’s a little bump in the afternoon to 2ft from the south, and the energy picks up to a moderate 121, but it’s cross-off and not doing much.

Wednesday and Thursday the 15th and 16th are just a rinse and repeat of small, cross-off, unexciting surf. Waves around 2ft to 3ft, weak energy, and the wind is just a bit too side-shore to be clean. Not worth the paddle.

Now, here’s where it gets interesting. Friday the 17th morning is the standout of the whole outlook. We’ve got a solid 4ft swell from the SE, but the period is a very long 17 seconds – that’s proper groundswell energy, with a combined energy of 799 (moderate) and the wind is a light cross-off from the S. This is expect very good surf conditions. The waves will have real shape and power, but at a beach break like Tsurigasaki, that long period might make it a bit straight and walled up. Still, the best bet on offer. The afternoon on Friday sees the swell jump to 7ft from the same SE direction, but the period drops to 15 seconds and the wind swings cross-shore, making it a bit of a chop. It’s still big, but it’s less clean. That 7ft+ swell is getting into the size where it’s only for experienced surfers.

Saturday the 18th holds size, with 7ft to 7ft from the SE, but it’s cross-on all day. The wind is from the ESE, so it’s going to be a bumpy, choppy mess. The energy is still strong (1136-1498), but the quality is marginal. If you’re a kite surfer, this setup might be fun, but for paddle surfing, it’s a struggle.

Sunday the 19th through to the end of the second week is a bit of a write-off. The wind switches onshore from the NE, pushing 7ft of swell into the beach for Sunday, but it’s onshore and messy. Monday the 20th and Tuesday the 21st the swell drops to 4ft-5ft, but the wind is still onshore (NE/ENE) at 12-16 mph, so it’s poor conditions. Wednesday the 22nd sees another pulse of size, with 7ft-7ft from the ESE and a long period of 13-14 seconds (strong energy at 1633), but again, it’s onshore wind. It’s big and powerful, but blown out.

From the 23rd onwards, it’s a steady decline. The swell drops under 5ft, the wind is cross-on or onshore, and the energy fades away to weak numbers. The 27th of July has a tiny 3ft from the ENE with a light onshore breeze – just a marginal, flat day.

So, the honest truth? The only real standout is Friday the 17th morning. Get out there early for the cleanest, best-shaped waves in the whole window. The rest of the period is either too small, too windy, or too big and messy. It’s a case of pick your moment and be ready for a bit of a challenge.

Rusty.
