Osaka's climate is similar to Tokyo but with a more pronounced urban heat effect. I visited during the humid summer and found the city's famous street food culture actually thrives in the heat — the covered arcades of Dotonbori provide perfect shelter from the sun. The data shows Osaka gets slightly warmer than Tokyo in summer, making air conditioning essential. Spring and autumn are the ideal windows for exploring the city's many temples and castles.
