Busan, South Korea Daily Water Report — August 26, 2026

Today, Busan's harbor is a mixed bag for water enthusiasts. If you're diving, you're in luck with an 8/10 suitability score, thanks to calm winds, manageable wave heights, and warm water temperatures. Boaters should also find favorable conditions, scoring a 7.5/10, although the slight drop from yesterday's 8.7/10 suggests a bit more caution is warranted. Fishing fans might want to hold off or pick their moments carefully, as the activity scores a modest 5.9/10. The solunar major periods from 13:15 to 15:15 and 01:15 to 03:15 could offer better chances, but the lack of tide data and falling barometric pressure might make for a less-than-stellar day on the line. The waxing gibbous moon at 95% illumination could also play a role in fish activity, but the impact is uncertain without tide information. Sailors will find today on par with the last couple of days, scoring 6/10. Light winds from the southeast, peaking at just under 17 knots, offer a gentle ride, but keep an eye on those gusts that could surprise you early in the morning. Surfing conditions remain mediocre at 5.3/10, with small wave heights around 0.18 meters and a gentle swell from the southwest. Kayakers will find the conditions slightly less favorable than yesterday, with a score of 6.6/10. The calmest seas are around midnight, so early risers might enjoy the smoothest paddling. Wildlife enthusiasts can expect a decent day with a score of 6.8/10, but again, without tide data, predicting the best viewing times is tricky. Looking ahead, expect a shift in conditions with increasing chances of rain from the 27th onward, peaking at nearly 98% on the 28th. Winds will remain light through the weekend, but swell and wave heights will increase slightly, so plan accordingly. Best bet: Dive into Busan's waters today while conditions are prime, and keep an eye on the weather as the week unfolds.
