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

Alright, let’s break this down. For Tsurigasaki Surfing Beach (Tokyo 2020), it’s a slow start with a long stretch of small, weak surf and tricky winds. Patience is key. The water temp is about 80°F, which is normal for the season.

The first decent surf is on Wednesday morning, July 29th. Tiny 2ft swell from the SE, with a 10-second period. The wind is light offshore from the WSW, so it’s clean and glassy. The combined energy is only 52, so it’s weak. It’s surfable, but nothing to write home about. The afternoon turns cross-shore and the swell drops.

Thursday, July 30th, has a little more in the afternoon. Swell is 2ft from the S, but with a short 7-second period, so it’s weak. The wind is cross-offshore from the SSW, keeping it clean. Energy is still low at 81. Not a standout.

Then a dry spell hits. From Friday, July 31st, through Saturday, August 1st, the surf is poor with small, messy waves and cross-onshore or onshore winds. Nothing worth paddling out for.

Sunday, August 2nd, shows a pulse. Morning sees 4ft SE swell with a long period of 15 seconds. That’s a proper groundswell, but it’s with a slight cross-onshore breeze from the ESE. The combined energy jumps to 607, so there’s moderate power. The afternoon gets bigger at 4ft, but the wind turns onshore from the E, making it messy. For a beach break, that long period might make it a bit straight, so it’s a gamble.

Monday, August 3rd, gets big but ugly. Swell hits 8ft in the morning, 10ft in the afternoon, both from the SE with a very long period of 17-18 seconds. The combined energy is massive—3802 to 4599. But the wind is a strong cross-onshore from the NNE and NE, creating choppy, lumpy conditions. This is expert-only, and even then, the wind ruins it.

Tuesday, August 4th, is worse. Swell pumps up to 13ft to 15ft from the SE, period 17 seconds, and the energy is through the roof (8399 to 10921). The wind is onshore from the NE, so it’s a washing machine. This is more for kite surfers than paddle surfers.

The best chance in the whole run is Wednesday, August 5th. The swell is huge at 18ft from the SE, with a period of 16-17 seconds. Energy is massive at 17752. The wind is cross-onshore from the NNE in the morning, but it’s a fresh breeze. The guidance says the swell is too big for this break, so it’s a no-go for surfing. The same goes for Thursday, August 6th morning, with 15ft swell and onshore wind.

After that, the rest from Thursday afternoon through Tuesday, August 13th, is a mix of marginal to poor conditions. Swell sizes drop from 8ft down to 3ft, with periods between 10 and 14 seconds. The winds are mostly cross-onshore or onshore, with some strong breezes and even a near gale on Tuesday, August 11th. The combined energy goes from strong (4585) down to weak (335). There’s no clean, well-shaped surf.

The standout is the Sunday, August 2nd morning session, with that 4ft, 15-second groundswell and light wind. It’s not perfect, but it’s the only window that works. Otherwise, it’s a waiting game. The surf is inconsistent, and the long-period swells are too big or wind-chopped. Tough run.
