Latest forecasts from major models and agencies indicate Beijing's high on August 18 will likely reach 30–31°C, reflecting a typical late-summer pattern with partly sunny skies, light southerly winds, and a modest chance of afternoon showers that could cap the peak. Recent model runs show consistency, with minimal day-to-day shifts in guidance, as the region remains under stable high pressure with dew points supporting humid but not extreme conditions. Historical August averages near 30°C provide climatological context, while traders monitor updates from the China Meteorological Administration and global ensembles ahead of resolution. Any strengthening of onshore flow or earlier convection could trim the maximum by 1–2°C.
