Buenos Aires vs Santiago

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.

Santiago

Santiago has a Mediterranean climate with hot, dry summers and cool, wet winters. The Andes are snowcapped from June through October. Air quality can suffer in winter when thermal inversions trap smog in the valley.

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.

Santiago

Santiago has an excellent Metro system and extensive bus network (Transantiago/RED). The Bip! card works across all public transit. Rush hour can be intense, but outside peak times the system runs smoothly.

Walkability: Central Santiago is very walkable. Lastarria, Bellavista, Providencia, and the Centro Historico are all best explored on foot. The city is flat between the two cerros (hills), making walking easy. Summer heat can be intense — carry water.
