Recent forecasts for Beijing on July 20 indicate daytime highs clustered near 29–30°C, shaped by the East Asian summer monsoon and peak rainy season conditions. Multiple models show expected thunderstorms and widespread cloud cover, which limit solar heating and keep maximum temperatures moderate despite typical July averages near 32°C. Official guidance highlights 20–46 mm of rainfall potential that day, a key factor suppressing peaks toward the market’s leading 28–30°C outcomes. Traders weigh short-term model runs from sources like the China Meteorological Administration against historical July variability, where isolated clearer periods can briefly push readings 1–2°C higher. Updated forecasts and observational data through July 19 will refine resolution odds ahead of the 24-hour maximum temperature measurement.
