Current ensemble forecasts from global and regional models, including guidance aligned with China Meteorological Administration analyses, converge on a daily maximum near 29–31°C in Shenzhen on June 13 amid early-summer monsoon conditions featuring high humidity above 75%, scattered convective showers, and persistent cloud cover that limits surface heating. Subtropical flow from the South China Sea supplies moisture while steering patterns favor afternoon instability rather than prolonged clear skies, keeping peaks close to the June climatological baseline of 30–31°C. Minor differences among leading outcomes reflect small uncertainties in exact timing of rain bands and boundary-layer mixing, with official station measurements expected to resolve the market shortly after the period ends.
