Trader consensus on Polymarket heavily favors 21°C (55%) and 22°C (40%) as Shanghai's highest temperature today, driven by the China Meteorological Administration's latest forecast ensemble projecting a daytime maximum near 21.5°C under partly cloudy skies and light southerly winds advecting warmer moist air from subtropical regions. This marks a step up from yesterday's observed high of 15.5°C at nearby stations and aligns with a recent warming trend, including a 19.4°C peak on March 22 amid spring's transition from cooler averages around 13°C. Model consensus shows low spread, with minimal risk of sub-20°C outcomes due to favorable diurnal heating, though minor cloud increases or wind shifts could nudge toward 22°C. Official hourly data from Shanghai Pudong and Hongqiao stations will confirm the peak by evening.
