Busan, South Korea Daily Water Report — September 1, 2026

Today in Busan Harbor, the water is calling, especially if you're into diving or boating. With a diving suitability score of 7.9/10, it's a great day to explore underwater, thanks to calm waves around 0.42 meters and a warm sea surface temperature of 28.9°C. Boaters can also enjoy a smooth ride with a score of 7.4/10, aided by gentle SSW winds at 4 knots, though gusts could reach nearly 20 knots by midday. If you're headed out for some fishing, today's score of 7.1/10 suggests fair conditions, but you might want to plan around the major solunar periods (2:49-4:49 AM and 2:49-4:49 PM) for the best chances. Surfing conditions are less thrilling, with a score of 5.2/10, as the modest 0.24m swell from 100 degrees won't provide much excitement. Kayakers will find the conditions decent, scoring 6.4/10, though the current at 4.6 m/s toward 45 degrees may require some extra paddling effort. The weather today is hot and humid, with temperatures peaking at 30.9°C, feeling like a steamy 35.8°C. Keep an eye on the sky as there's a rain window from 11 AM to 5 PM, though precipitation is expected to be negligible. Atmospheric visibility is moderate at 6.2 km, so it's a good day to enjoy the water but keep your sunscreen handy, as the UV index is a robust 6.55. Looking ahead, the next few days bring fluctuating conditions. Expect calmer waters tomorrow but brace yourself for rising waves and winds by the weekend. If you're planning an outing, Saturday might be a wash with waves surging up to 1.8 meters. For today, if diving is on your agenda, seize the day and make a splash before the weather takes a turn later in the week.
