Trader consensus on Polymarket positions 20°C as the leading outcome at 61.5% implied probability for Mexico City's highest temperature today, driven by the latest Servicio Meteorológico Nacional (SMN) guidance and GFS/ECMWF model ensembles forecasting peaks of 19–20°C amid northerly winds gusting 40–60 km/h and scattered morning showers. These conditions, remnants of a recent "norte" surge over central Mexico, have cooled the high-elevation basin (2,240 meters above sea level), where thermal inversions often cap daytime heating below March norms of 24–26°C. Over the past 48 hours, actual highs hovered 19–22°C with cloudy skies limiting insolation; 19°C at 40.5% reflects persistent overcast risks, while 21°C (28.0%) eyes potential afternoon clearing. Watch hourly Benito Juárez Airport (MMMX) METARs for resolution-defining observations through evening.
