Rio doesn't have seasons the way Northern Hemisphere cities do — it has rhythms. I spent Carnival there once and the energy is indescribable, but the heat and crowds aren't for everyone. The data shows March-May as the sweet spot: still warm, less humid, fewer tourists. What the numbers can't capture is the late afternoon light on Ipanema — that's when Rio feels most itself. December-February is festive but exhausting; pace yourself.
