Recent forecast runs from agencies including the UK Met Office and Chinese meteorological sources show Guangzhou's August 29 daytime high centering on 32–36 °C amid scattered thunderstorms and moderate rain, driven by lingering subtropical moisture and variable convective timing. High humidity near 70–90 % and light winds typical of the monsoon transition period limit extreme heating, while model consensus has tightened over the past 48 hours around mid-30s Celsius values consistent with August climatology of roughly 33 °C. Traders track official station observations from the China Meteorological Administration for resolution, with any late-model shifts in storm coverage or timing representing the main source of remaining uncertainty before the event.
