Recent numerical weather prediction models from global and regional ensembles indicate a highest temperature in Beijing on August 25 most likely between 30–33 °C, with thunderstorm activity and associated cloud cover expected to moderate peak heating. Southerly flow and high humidity favor convective development during afternoon hours, limiting insolation and surface warming compared to clearer late-summer days. Historical climatology shows an average high near 29.7 °C for the date, while recent model runs exhibit tight clustering around 31–32 °C amid ongoing monsoon moisture. Traders assign the highest probabilities to 31–33 °C outcomes because ensemble spreads and timing uncertainties in precipitation could shift the daily maximum by 1–2 °C. Updated China Meteorological Administration guidance and next model cycles will further refine these ranges before resolution.
