Trader consensus on Polymarket reflects tight clustering around 29–31°C for Shenzhen's highest temperature on April 13, driven by recent clearing skies following a weak frontal system's departure over the past 48 hours, which capped prior peaks at 29–30°C on April 9–10 amid lingering clouds. Current forecasts from monitoring agencies indicate mostly sunny conditions with southerly winds at 15–20 km/h and humidity near 55–60%, supporting highs around 30–32°C per extended model runs, though urban sea breezes and minor cloud variability introduce uncertainty differentiating exact peaks. Official observations at Shenzhen Bao'an International Airport will resolve the market; watch China Meteorological Administration updates tomorrow for refined guidance as diurnal heating patterns clarify.
