Current forecast models and real-time observations from agencies like the China Meteorological Administration indicate a minimum temperature of 23°C in Guangzhou on September 10, 2026, aligning with the market's near-certain 99.7% implied probability. This subtropical location typically sees September overnight lows averaging 24.6°C based on 1991–2020 climatology, with recent days showing stable northerly flow and partly cloudy conditions preventing significant radiational cooling or cold advection. No major weather systems or model divergences suggest deviation from this range. The outcome could shift only under an unforecasted sharp drop, such as from unexpected frontal passage or measurement anomaly at official stations, though current data make such scenarios improbable before resolution.
