Osaka's Climate
Osaka has a humid subtropical climate with four distinct seasons and a reputation as one of Japan's muggiest summer cities. The tsuyu rainy season runs from about June to mid-July, followed by hot, sticky July and August with highs often 33–35°C, and a typhoon season peaking in August and September. Winters from December to February are cold and dry, roughly 2–9°C, with snow that rarely settles thanks to the city's sheltered inland-bay position.
