Recent numerical weather prediction models from agencies like the China Meteorological Administration converge on a daytime maximum near 33°C for Shenzhen on August 16, supporting the market's leading 42% implied probability there and 24.5% for 34°C. Persistent subtropical high humidity, elevated sea surface temperatures, and a mix of cloud cover with scattered thunderstorms are capping radiative heating and steering patterns, consistent with late-summer climatology where August highs average 32°C. Updated runs show limited model spread around the 32–34°C range, though minor shifts in monsoon flow or convective timing could adjust the peak by 1°C before resolution.
