Trader consensus on Polymarket overwhelmingly favors 31°C as Shenzhen's highest temperature on April 16, driven by observational data from the Shenzhen Bao'an International Airport weather station—the market's official resolution source—recording a midday peak of 31°C under partly cloudy skies. Hourly readings confirm the diurnal cycle topped out around early afternoon, followed by steady cooling to the low 20s°C by late day amid moderating sea breezes typical of the region's subtropical monsoon climate. This aligns with recent China Meteorological Administration updates and ensemble model post-analysis showing no further intensification potential. A realistic challenge would require an anomalous late-evening heat spike from sudden clearing, though solar forcing diminishes sharply after sunset, making 32°C+ improbable barring data revisions. Final station reports expected within 24 hours.
