Recent short-range forecasts from the China Meteorological Administration and global models indicate Beijing’s August 12 maximum will likely fall in the mid-to-upper 20s °C, driven by increased cloud cover, possible light rain, and reduced solar insolation compared with clearer conditions earlier in the week. With the 26 °C and 27 °C bins tied at 28.5 % implied probability and 28 °C close behind, traders are reflecting genuine forecast spread arising from differences in timing of any showers and boundary-layer moisture. Historical August climatology centers near 30 °C, but the current pattern shows a modest cooling signal that narrows the range of plausible outcomes and keeps probabilities clustered across these three bins rather than favoring a single threshold. Updated model runs and the evening forecast on August 11 will provide the next key data points for resolution.
