Recent official forecasts from sources like WeatherBug, Weather Atlas, and regional models converge on a maximum temperature of 30–31°C for Shenzhen on October 4, driven by subtropical easterly flow, high humidity near 80%, and scattered thunderstorms that limit daytime heating while sustaining warmth overnight. These conditions align with early October climatology, where averages hover around 29–30°C amid the post-monsoon transition, though variable rainfall introduces modest uncertainty in exact peak readings. Trader consensus favoring 31°C reflects this narrow forecast range, with lower probabilities for 32°C or below reflecting model agreement on modest instability rather than extreme outliers. Updated guidance from monitoring agencies on October 3 could refine land-sea breeze influences before resolution.
