Recent official forecasts from sources like timeanddate and regional models indicate afternoon highs for Chengdu on July 8 around 35–37°C under a mix of broken clouds and early thunderstorms, aligning with typical Sichuan Basin summer conditions where topography traps heat and limits ventilation. Trader sentiment clusters near 37–39°C because subtle variations in solar insolation, boundary-layer mixing, and the precise timing of convective showers can shift the daily maximum by 1–2°C. High relative humidity further reduces evaporative cooling, while any delay in monsoon-driven rainfall allows greater daytime warming. Model spread and the two-day forecast horizon sustain the closely matched probabilities across these outcomes.
