Trader consensus assigns a 100% implied probability to 18°C as Shanghai's highest temperature on April 22, driven by confirmed observations from the official weather station at Shanghai Pudong International Airport—the market's resolution source—peaking at 18°C during midday hours. Overcast conditions and light southerly winds under weak high-pressure influence capped warming by reducing solar insolation, consistent with China Meteorological Administration short-range forecasts and April climatological averages of 18°C highs. While inherent measurement uncertainties exist, realistic challenges like unexpected clearing for late-afternoon heating are improbable given sunset timing and persistent cloud cover; traders await the final daily meteorological summary for confirmation.
