Recent forecasts from multiple models, including those aligned with Shenzhen Meteorological Bureau guidance, indicate a highest temperature near 30–31°C on September 2, consistent with the market’s tight clustering around 29–31°C. In Shenzhen’s subtropical monsoon climate, early-September highs typically average 31°C amid weakening summer monsoon flow and northwest steering winds that can limit afternoon heating through increased cloud cover or scattered convection. Current conditions feature lingering moisture from recent heavy rain episodes, with models showing 30–45% thunderstorm chances that may cap peaks if showers develop before peak insolation; clearer intervals could allow readings to reach 31–32°C. This narrow range reflects standard ensemble spread in short-range numerical weather prediction for diurnal maximums, with resolution hinging on the precise timing and coverage of any localized thunderstorms.
