Hot and humid (24-25°C) with afternoon thunderstorms. Many porteños escape to the coast, leaving the city quieter. January is the vacation month — some restaurants and shows close.
March and April offer comfortable temperatures (17-22°C) with autumn colours in Palermo parks. The cultural season opens with new theatre and film festival premieres.
