Pressure and weather in Onna
Onna’s subtropical marine climate has an early-summer Baiu rainy season and exposure to western Pacific typhoons during the warmer months. Winter northerly monsoon flow often brings cloud and cooler air over the sea. A nearby typhoon can create much larger pressure changes than an ordinary coastal shower, and storm tracks matter as much as local cloud cover.
