Latest forecast consensus from global and regional models points to a daytime high near 32°C in Shenzhen on September 26, driven by light southerly winds, partial cloud cover, and stable subtropical high pressure that limits strong surface heating. Official guidance and recent observations place the expected maximum between 31–33°C, with minimal precipitation risk and typical late-September humidity around 60–75%. This positioning explains the market's strong weighting toward 32°C, while the spread to 31°C and 33°C reflects remaining model variability in cloud timing and boundary-layer mixing. Historical September maxima average near 31°C, providing climatological context for the narrow distribution. Updated model runs and any China Meteorological Administration revisions ahead of resolution remain the key near-term catalysts.
