Though Osaka's climate isn't necessarily its main draw, the weather in the city is temperate and fairly pleasant through most of the year. Winter is mild and doesn't bring extreme cold, although summer's hot, humid and rainy days can be uncomfortable.

In June, temperatures can reach 95°F (35°C), with the heat compounded by high humidity. Rain falls year-round in Osaka, with June not only being the city's hottest month, but also its wettest. December and January offer a short respite from the rain, which begins to ramp up again in February. Winters, from December to February, are mild with the mercury tending to remain comfortably above 50°F (10°C).
