Recent forecast model runs from agencies including the China Meteorological Administration and international ensembles indicate a high near 29°C for Shenzhen on October 5, following heavy rain and thunderstorms on October 3–4 that suppressed daytime maxima. Clearing to partly cloudy skies under northeasterly flow at 8–10 m/s is expected to allow modest daytime heating while limiting extreme values, consistent with early-October climatology of 28–30°C highs. Trader consensus around 29°C (34.5%) versus nearby 28°C and 30°C outcomes reflects genuine uncertainty in boundary-layer moisture, cloud timing, and local urban heat effects, with new observational data and updated model guidance likely to refine probabilities ahead of resolution.
