Buenos Aires vs Lima

Buenos Aires

Buenos Aires has a humid subtropical climate with hot summers and mild winters. The city rarely experiences extreme cold, but summer humidity can be intense. Rain is distributed fairly evenly throughout the year.

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.

Buenos Aires

Buenos Aires has an extensive public transit network centered on the Subte (metro), colectivos (buses), and a commuter rail system. The SUBE rechargeable card is required for all public transit and costs ARS 3,000 (~$3 USD). Individual rides are extremely cheap by international standards.

Walkability: Central Buenos Aires is flat and very walkable. The grid layout makes navigation easy. Palermo, San Telmo, Recoleta, and the Microcentro are all best explored on foot. Sidewalks can be uneven — watch your step, especially on tree-lined streets where roots push up tiles.

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.
