**Forecast models from sources like the Guangdong Meteorological Bureau and international services (e.g., GFS-based outlooks) currently indicate a minimum temperature of 26–28 °C for Guangzhou on August 29, 2026, with overnight lows likely falling no lower than the mid-20s amid persistently high humidity and scattered showers.** Trader consensus reflected in the tightly clustered probabilities around 25–28 °C arises because dew points remain elevated near 26–28 °C, limiting nocturnal radiative cooling even under partly cloudy skies. Light winds and urban heat retention in the city further moderate temperature drops, while any passing showers add latent heat and cloud cover that suppress further cooling. Historical August climatology for the region shows typical lows near 24 °C, but current warm, moist air mass—sustained by subtropical flow without an approaching cold front or typhoon—keeps the distribution centered several degrees higher. Model runs differ modestly on exact timing of any brief clear spells or rain intensity overnight, producing the narrow spread across leading outcomes; extremes below 22 °C or above 30 °C carry low implied odds because sustained warmth and moisture make those thresholds unlikely under present atmospheric conditions. Updated model guidance or new observational data on cloud trends and humidity tomorrow morning could refine the final minimum.
