Tokyo Bay, Japan Daily Water Report — August 31, 2026

The waters of Tokyo Bay are offering a splendid day for boating and kayaking, with scores of 8.5/10 and 8.2/10, respectively. Today’s gentle winds and minimal wave action create ideal conditions for those looking to glide smoothly across the bay. The winds are light, generally around 2 knots from the east, with gusts peaking at 16.7 knots later in the afternoon, so keep an eye on the clock if you prefer calmer outings. For anglers, the fishing score holds steady at 6.6/10, unchanged from yesterday. The solunar periods suggest the best bites might come early in the afternoon, between 13:15 and 15:15. No rain is expected, and with the barometric pressure on the rise, it’s a good day to cast your line without worrying about getting wet. Surfers might find today a bit lackluster, with a score of 4.6/10. The waves are modest, peaking at just 0.3 meters, so you might need to temper expectations for any thrilling rides. The calmest seas are around 2:00 AM, but if you're chasing those early morning waves, you might be left wanting more. Divers will enjoy favorable conditions with a score of 7.6/10, thanks to the stable marine surface temperatures at 28.2°C and manageable wave heights. Wildlife enthusiasts can expect a decent day as well, with a score of 7.1/10, although the lack of tide data means a bit of guesswork is involved. Looking ahead, the next few days will gradually bring more wind and a higher chance of rain, especially by September 4th, when waves could climb to 1.7 meters. If you’re planning an outing, today is your best bet for serene waters and clear skies. So grab your gear and make the most of this splendid day in Tokyo Bay!
