What you gain in December

  • New Year's Eve is approaching: the city building toward the Copacabana celebration
  • Summer beach culture at full capacity: the best Ipanema nights begin in December
  • Christmas in Rio has a genuinely tropical atmosphere — beach barbecues and outdoor parties

What you sacrifice

  • 246mm: very heavy summer rain — afternoon plans must be flexible
  • Prices rising steeply toward New Year and Carnival: book early or pay significantly more
  • 30°C+ with 77% humidity: outdoor sightseeing best confined to morning hours
