Recent rainfall and persistent cloud cover across Beijing have suppressed daytime heating, keeping surface temperatures below typical late-August peaks near 30–32 °C. Official forecasts from the China Meteorological Administration and multiple numerical models indicate afternoon maxima of 28–30 °C under mostly cloudy skies with light winds and residual moisture, limiting insolation and evaporative cooling. This pattern follows several days of showers that lowered soil and boundary-layer temperatures, reducing the likelihood of rapid afternoon warming. Market-implied odds cluster tightly around 30–31 °C because models show only modest differences in cloud timing and thickness; a brief clearing could push readings to 32 °C, while continued rain would cap them near 29 °C. Updated hourly observations and evening model runs will resolve the final daily maximum.
