Latest China Meteorological Administration forecasts and global models like GFS project Beijing's April 19 high near 21–22°C, driving trader sentiment toward that outcome at 24.5% implied probability, following recent highs in the upper 20s to low 30s under sunny southerly flow. A post-frontal northerly breeze and increasing cloud cover—potentially overcast or light rain—are expected to cap diurnal heating, with model ensembles showing slight spread: ECMWF leaning cooler around 21°C due to persistent stratus, while GFS hints at 23–24°C if partial clearing occurs. April climatological averages hover at 20–22°C, amplifying uncertainty in boundary layer mixing and frontal timing; monitor CMA's evening update for refined guidance ahead of resolution via official airport observations.
