Official observations from Chongqing Jiangbei International Airport, the reference station for resolution, confirm the highest temperature on April 18, 2026, reached 31°C (88°F) around 5:00 p.m. local time under mostly clear skies with light winds, enabling peak solar heating consistent with spring climatology in the region—where April averages hover around 23°C but allow spikes to 30°C+ on sunny days. Forecasts from the Chongqing Meteorological Bureau accurately predicted center-city highs of 31°C amid stable high-pressure conditions, driving trader consensus to 100% implied probability for this outcome. Realistic challenges would require rare data revisions from quality control processes or discrepancies across official monitoring sites, though such events are exceedingly uncommon post-verification.
