Conditions at Popov Island in August
August: Typhoon Season's Wildcard
August remains small on average, 0.5m (1.5-2ft) at 5.3s, but the late-summer typhoon season adds a wildcard. Swell direction still favors the south quadrant (S 34%, SSE 20%, SE 19%, SSW 12%), and while most waves are tiny, the occasional tropical cyclone tracking north through the Sea of Japan can send a pulse of longer-period S/SSW swell our way. The catch is that these systems also bring southerly gales. Wind observations show SSE (19%), S (17%), and SE (13%) dominating, with ideal wind at only 8%. So even when the swell comes, it is usually screaming onshore.
Water temp peaks at 21.2°C, air at 21.3°C, and August is the wettest month with 4.90mm/day. If a typhoon passes at the right distance, Popov can briefly wake up, but most days are flat and mushy.
