Trader consensus clusters tightly around 30–32°C for Shenzhen’s peak on August 24 because multiple forecast models indicate widespread cloud cover, thundery showers, and relative humidity near 85% will limit daytime heating. Evaporative cooling from rainfall and reduced insolation under overcast skies typically suppress maxima by 1–3°C relative to clear-sky climatology, keeping values near the long-term August average high of 31–32°C. Light southerly flow offers little advection of warmer air, while the absence of a strong subtropical ridge reduces the likelihood of 34°C+ readings. Official observations from the China Meteorological Administration will determine resolution, with any last-minute model shifts in precipitation timing or intensity able to tip the narrow 30–32°C band.
