Busan, South Korea Daily Water Report — August 31, 2026

Today in Busan Harbor, the water's calling, especially for those with a taste for diving and boating. With a diving suitability score of 7.6/10, the conditions are favorable for an underwater adventure. The water temperature is a pleasant 28.9°C, and with wave heights steady around 0.5m, divers can expect a relatively smooth experience. Boaters are also in for a treat with a 7.1/10 score, thanks to manageable wind conditions peaking at 6.5 knots and a gentle ocean current. However, if you're looking to surf, you might want to temper your expectations. The 5.2/10 score reflects the modest wave height and short period, which won't be offering any thrilling rides today. Compared to recent days, the surfing scene remains subdued, echoing yesterday's calm but not quite as favorable as the 6.2/10 peak we saw on the 28th. For anglers, a 6.2/10 score suggests a decent day, particularly during the major solunar periods from 01:59 to 03:59 and 13:59 to 15:59. These windows, coupled with rising barometric pressure, could improve your chances of a good catch. Looking ahead, the weather takes a wetter turn with an 82% chance of rain tomorrow. The wind and waves remain relatively calm through the 2nd, but by the 3rd, we anticipate a spike in wave height, reaching up to 1.0m, signaling the start of a more dynamic marine environment. By the 4th, expect waves to crest between 1.0-1.4m, challenging sailors and surfers alike. For today, though, if you’re a diver or boater, the harbor is your playground. Enjoy the calm before the storm, both literally and figuratively, and make the most of these serene conditions.
