Trader consensus around 29–32°C for Shenzhen’s August 4 maximum reflects short-range model guidance showing afternoon peaks tempered by widespread cloud cover, thunderstorms, and elevated humidity from the East Asian monsoon. Official forecasts from agencies such as the China Meteorological Administration indicate daily highs near 29°C with isolated convection limiting surface heating, consistent with typical August variability around the 32°C climatological mean. The tight spread among leading outcomes captures genuine forecast uncertainty in timing and intensity of rain bands, which can shift the realized maximum by 2–3°C depending on the exact steering pattern and boundary-layer moisture. Updated model runs and next-day observations from local stations will narrow the range before resolution.
