Tokyo Bay, Japan Daily Water Report — August 26, 2026

Today in Tokyo Bay, the winds are blowing south at a lively 10 knots, with gusts reaching 19 knots at times, making it a prime day for sailing enthusiasts who enjoy a bit of a challenge. With a sailing score of 8.6 out of 10, the conditions are favorable, though not quite as stellar as two days ago when the score hit 9.2. The water temperature is a warm 27.8°C, slightly above the average, which should make for a comfortable day on the water. For divers, the conditions are quite inviting with a score of 8.1 out of 10. The relatively calm wave height, peaking at just 0.44 meters, and good water temperature contribute to a pleasant underwater experience. However, keep an eye on visibility as atmospheric conditions suggest some cloud cover. Boaters will find the wind and wave conditions manageable, scoring a 6.8, down a bit from the 7.6 on the 24th. The wind waves are gentle at 0.16 meters, though the ocean current is a bit brisk at 0.9 m/s heading north. Kayakers, on the other hand, might find the current challenging, reflected in a lower score of 4.8. Fishing sees a moderate score of 5.6, with solunar periods suggesting a good catch during the afternoon major period from 12:31 to 14:31. Surfing isn't the highlight today, with a score of 5.1, as the swell remains modest and the wind isn't quite aligned for ideal conditions. Looking ahead, the weather seems to be cooling down with increasing chances of rain, particularly on the 27th and 28th. Winds are expected to mellow out significantly by the end of the month, which could make for more relaxed boating and kayaking conditions. For those seeking the best experience today, sailing offers the most promise with its robust winds and manageable waves—hoist those sails and enjoy the ride!
