Lima vs Rio de Janeiro

Lima

Lima has a unique desert-coastal climate. It almost never rains (under 10 mm per year), but a persistent coastal fog called "garua" blankets the city from May through November. December through April are sunny and warm. The Humboldt Current keeps temperatures mild year-round.

Rio de Janeiro

Rio has a tropical savanna climate with hot, humid summers (December-March) and warm, drier winters (June-August). It rarely drops below 20°C. The city is warm enough for beach activities year-round, though summer rain can be intense.

Lima

Lima's traffic is notoriously congested. The Metro Line 1 (above-ground) and the Metropolitano BRT (bus rapid transit) are the most efficient public transit options. Ride-hailing apps are the safest and most convenient way to get around. The city is working on expanding the Metro system.

Walkability: Miraflores and Barranco are very walkable with pleasant tree-lined streets and the coastal Malecon boardwalk connecting them. The Centro Historico is walkable during daylight hours. Between districts, you'll need transit — Lima is a sprawling city of over 10 million people.

Rio de Janeiro

Rio has a metro system, bus network, light rail (VLT), and widespread ride-hailing via Uber and 99. The metro is the safest and most reliable option for tourists. Buses are cheap but can be confusing and less safe for visitors unfamiliar with routes.

Walkability: Ipanema, Leblon, and the Copacabana beachfront are very walkable. The beach promenades are excellent for walking and cycling. Centro is walkable during the day but sparse at night. The city is large and hilly — metro and Uber fill the gaps.
