Current ensemble forecasts point to minimum temperatures in Guangzhou on August 26 clustering between 25–28 °C, consistent with the tightly bunched market-implied odds around those levels. Persistent thunderstorm activity and extensive cloud cover are limiting overnight radiative cooling under high humidity, while steering flow from the southeast maintains a narrow diurnal range. Official guidance from regional models shows only modest day-to-day shifts in the expected low, with precipitation timing remaining the key variable that could push the minimum slightly lower or higher within the favored band. Historical August lows average near 25 °C, providing climatological support for the current trader consensus.
