Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 17°C in Shanghai on April 13, driven by hourly observations from the China Meteorological Administration's Xujiahui station peaking at this mark amid persistent overcast skies and light rain from a lingering frontal system. This moist, cooler air mass has suppressed daytime heating below the mid-April climatological average of 19°C at the station, consistent with recent GFS and ECMWF model runs capping maxima under similar conditions seen on April 11 (19°C high). With sunset approaching around 6:20 p.m. local time and solar forcing waning, realistic challenges are minimal—only an improbable extended clearing could yield a late-afternoon spike, but official daily maximums rarely revise upward post-peak. Final CMA confirmation expected within 24 hours.
