Recent numerical weather prediction models from sources like the China Meteorological Administration place Shenzhen’s June 5 maximum near 34 °C under typical early-summer subtropical monsoon conditions. Elevated boundary-layer moisture and scattered afternoon thunderstorms are expected to limit peak heating, with earlier or heavier convection likely capping readings at 33–34 °C while delayed storms or clearer intervals could briefly push values to 35–36 °C. Official forecasts show highs of 33–35 °C with light southerly flow, consistent with the closely matched market-implied odds across the 35 °C, 36 °C, and 37 °C+ outcomes. The inherent spread in model timing for convective initiation creates genuine uncertainty in the exact daily peak.
