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

Alright, let’s talk Tsurigasaki Surfing Beach, the Olympic spot. The next couple of weeks are a real mixed bag. The first few days are pretty flat and weak, with small, short-period swell and cross-shore winds that aren't helping. The combined energy is a weak 174 (moderate wave energy), so don’t expect much push. Water temp is about normal for this time of year.

We’ve got a dry spell for the first week, honestly. The 19th, Sunday morning, shows a little 4ft swell from the ESE with a period of 9 seconds and a clean cross-offshore wind. That’s surfable, but it’s short-period and inconsistent. The energy is 317 (moderate wave energy), and it’s the best of a weak bunch.

Then Monday through Wednesday is a slog. Tiny waves, mostly under 3ft, with wind that’s either cross-off or glassy but the swell is just too small to get excited about. By Wednesday morning the 22nd, it goes glassy, but with only 3ft of 10-second E swell, the energy is a weak 162 (moderate wave energy). The afternoon has a risk of thunderstorms, so keep an eye on the sky.

Thursday the 23rd and Friday the 24th are a write-off – onshore wind and energy dropping to 74 (weak wave energy). Saturday the 25th morning is clean but small, with 2ft from the SSE at 10 seconds.

Now, here’s where it gets interesting. The real standout is Monday the 27th. The morning brings a clean 3ft groundswell from the SSE, with a long 14-second period, and the combined energy jumps to 440 (moderate wave energy). That’s a solid, long-period groundswell that will wrap in nicely. The afternoon gets bigger, with 6ft from the SSE at 12 seconds, and energy surging to 1109 (strong wave energy). It’s a bit more powerful, but the wind stays clean cross-offshore. This is the best window in the whole forecast.

Tuesday the 28th and Wednesday the 29th are for experts only. Swell heights hit 7ft to 10ft from the SSE, with periods of 12-14 seconds and energy readings of 1311 (strong wave energy) up to 3354 (strong wave energy). The winds are cross-shore, so there’s some chop, but this is big, powerful, long-period groundswell. It’s too big for beginners, and on a beach break like Tsurigasaki, the long period might make it break a bit straight. It’s raw and heavy.

By Thursday the 30th and Friday the 31st, the swell holds around 7ft from the S, with a 14-second period. The Friday afternoon is the pick of that run, with cross-offshore winds and clean conditions. The energy is still high at 2019 (strong wave energy), and it’s excellent for experienced surfers – but not for the faint-hearted.

The first week of August drops off fast. Small, messy, and nothing to plan a trip around.

So, bottom line: the best on offer is Monday the 27th, especially the morning session with that clean, long-period groundswell. Tuesday and Wednesday are for the brave. The rest is mostly small or messy.
