Rain season
Osaka's tsuyu (rainy season) runs mid-June to mid-July — sustained grey, humid days with regular rain. Typhoons in August–September are a serious hazard; Osaka Bay amplifies coastal flooding during storm surges. Annual rainfall averages 1,300mm, with typhoon season responsible for many single-day extremes. Winters are cold and dry; spring brings light showers.
