Recent forecasts from meteorological agencies place Beijing's September 5 maximum in the 32–34 °C range under mostly clear skies, light southerly winds, and low humidity, with peak heating expected in the early afternoon. Official guidance and ensemble models show only modest spread around this window, reflecting typical late-summer conditions without strong advection or cloud cover to suppress temperatures. Traders assign roughly equal weight to 33 °C and 34 °C because small differences in boundary-layer mixing or station-specific readings can shift the official daily maximum across that threshold; the modest probability on 32 °C captures downside risk if marine air or earlier cloud build-up limits the peak. Updated model runs and real-time surface observations through the afternoon will determine which value ultimately resolves the market.
