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

Righto, let's see what we've got here. This whole 16-day stretch for Tsurigasaki is a bit of a mixed bag, but there are definitely windows of opportunity if you play your cards right. The water's sittin' at 72°—that's about 4° cooler than what you'd expect for July, so grab a slightly thicker spring suit if you're sensitive to it.

The first real whisper of decent surf hits us on Wednesday, July 10th. We've got a solid SE groundswell pushing 7ft with a very long 16-second period, and the wind is a light cross-offshore. That's clean, that's got push—it's the standout of the whole first week. The combined energy is strong at 2149, so you'll feel that juice. It's an exposed beach break, so with that long-period swell (over 15 seconds), the sets will be powerful and consistent but might close out a bit. Still, for experienced intermediates, Wednesday morning is the moment.

Thursday the 11th holds some similar size early—7ft from the S, still a long 17-second period—but the wind picks up to a moderate breeze in the arvo. The morning session might still be worth it, but the afternoon drops right off to nothing.

Then we hit a real dry spell. From Saturday the 12th right through to about Tuesday the 15th of July, we’re lookin' at weak, short-period junk. Swell drops to under 3ft, periods around 8 or 9 seconds, and the energy numbers barely crack 100 some days. Not worth paddlin' out for.

Things start to wake up again on Wednesday the 15th. We get a touch of chest-high 6ft SSE swell with 14-second period, and light cross-shore winds—okay for a run after work, but still pretty average.

Now here’s where it gets interesting for the long-range crew. Jump ahead to Monday, July 20th. The energy numbers absolutely explode—7924, which is seriously strong. We’re looking at a heavy 13ft ESE swell, but the wind is onshore and choppy. That’s big, messy, and borderline dangerous—more for the kite crew than paddle surfers. If you’re an expert on a big board, maybe, but it’s not pretty.

Then—Tuesday, July 21st. That’s the real standout of the whole outlook. The swell drops to a still-chunky 12ft from the E, but the wind goes glassy in the morning. Absolutely glassy. Combined energy is massive at 4248, and it’s clean. That’s a rare treat for this break. Again, at 12ft this is expert-only territory, but if you’ve got the skills, Tuesday morning July 21st is the day to circle on your calendar. The afternoon stays clean too with 8ft and cross-offshore wind.

After that, the 22nd and 23rd look like a write-off with onshore wind and dropping size.

So to boil it down: the best on offer is Wednesday morning July 10th for the first week, and Tuesday morning July 21st for the second week. The 21st is the real gem, but keep in mind it’s a long way out so forecasts can wobble. The middle week (12th–15th) is a total gap—save your energy.

Crowds at Tsurigasaki can pop off, especially when it's good, so be ready for company.

Rusty.
