Trader consensus on Polymarket heavily favors Mexico City highs of 23–24°C on April 6, reflecting Servicio Meteorológico Nacional forecasts influenced by the recent Frente Frío 43 and trailing polar air mass, which arrived in northern Mexico on April 4 and is advancing southward. This system brings increased cloud cover, moderate rain chances, and cold air advection that suppresses daytime heating at the city's 2,240-meter elevation, where typical April highs average 26°C. Model ensembles show tight clustering around these levels due to partial solar insolation amid showers, though uncertainty persists in the front's exact penetration and precipitation timing—stronger cooling could push toward 22°C, while quicker clearing favors 25°C. Watch SMN updates Sunday for refined guidance ahead of resolution.
