Short-term numerical weather prediction models from agencies including the China Meteorological Administration indicate a daytime maximum near 31–32°C for Shenzhen on August 14, with moderate rain or showers expected to limit solar heating and produce the current tight clustering of trader-implied probabilities around those values. In Shenzhen’s humid subtropical regime, afternoon convection and cloud cover introduce typical 1–2°C variability in peak readings, while climatological August highs average 32°C with occasional excursions above 34°C under clearer skies. Ensemble spreads remain modest two days out, but updated runs tomorrow morning and any shifts in steering flow or moisture will refine the exact threshold for market resolution.
