Pressure and weather in Chatan
Chatan is a coastal town on the western side of central Okinawa Island, known for the seaside American Village district and its close neighbor, Kadena Air Base. Okinawa lies far to the south of mainland Japan, in the subtropical waters between Kyushu and Taiwan, and its weather follows a different calendar. The rainy season, tsuyu, arrives in early May and usually ends in late June, weeks ahead of Tokyo, as the seasonal front stalls over the Ryukyu Islands and brings long spells of heavy rain and humid, gray skies with a sluggish barometer. Summer is hot and humid under the Pacific high, but it is also typhoon season. From July through October, and especially in August and September, tropical cyclones track toward Okinawa, and the island sits directly in their most common path. A direct hit can bring pressure falls of fifty hectopascals or more within a day, ferocious winds and torrential rain, and residents routinely prepare for several typhoons each year. In winter, the northeast monsoon brings cool, gusty winds and cloudy weather from the Asian continent, with more regular pressure changes as fronts pass to the north.
