The latest forecasts from Argentina's Servicio Meteorológico Nacional (SMN) and ensemble models like GFS and ECMWF project a maximum temperature of 18°C in Buenos Aires today, under hazy sunshine and light winds, fueling trader consensus at 67% implied probability for that outcome. Morning observations show cool starts around 8–10°C, with afternoon warming expected amid high pressure dominance and minimal cloud cover, aligning with mid-May climatological norms of 17–19°C highs during autumn. The 30.5% on 19°C reflects potential urban heat island effects or slight model upside, while lower outcomes fade due to insufficient cold air advection. Final resolution hinges on Aeroparque station readings by evening, with updates possible as diurnal heating peaks.
