Recent forecasts from multiple models indicate overnight lows in Guangzhou for August 29 likely ranging 26–28°C amid persistent humidity near 70–90% and variable cloud cover from monsoon influences, limiting radiative cooling. Scattered showers and light winds further moderate temperature drops, while the urban heat island effect may elevate readings slightly above rural baselines. Historical August minima average around 25°C, but current conditions and model spread create tight clustering of trader-implied odds near 24–30°C, with lower probabilities assigned to extremes due to forecast uncertainty in precipitation timing and atmospheric stability ahead of the China Meteorological Administration's next updates.
