Field notes
Hot humid summers (December–February) hit 30°C+ regularly, with a few brutal heat waves. Winters are mild rather than cold (10–12°C average), but buildings are often un-heated, so indoor life can be surprisingly cool. Spring (October–November) and autumn (March–April) are peak.
Cost of living in Buenos Aires: ~$1,380/mo
