Recent forecast data from multiple meteorological sources indicate persistent cloud cover, high humidity, and scattered showers or thunderstorms across Shenzhen on October 3, 2026, which are suppressing daytime heating and positioning the daily maximum near 29–30 °C. These conditions align with the seasonal decline in subtropical autumn temperatures, where October averages hover around 29 °C, and current model consensus shows limited potential for stronger insolation or southerly flow that could push readings to 31 °C or higher. The market’s heaviest weighting on 30 °C (46 %) followed by 29 °C (34.5 %) reflects this tight clustering of official guidance, with only modest probability assigned to outliers given the stable steering patterns and moisture advection observed in recent hours. Updated model runs and surface observations through the afternoon will determine final resolution.
