Latest ensemble guidance from the China Meteorological Administration and global models like GFS places Chongqing’s May 18 maximum in a tight 24–27 °C cluster, driven by persistent light southerly flow and variable low-level moisture that caps afternoon heating. Small differences in cloud cover and boundary-layer mixing over the Sichuan Basin determine whether readings top out near the long-term mid-May average of roughly 26 °C or remain a degree cooler. With resolution less than 48 hours away, traders are pricing the genuine short-range uncertainty in these variables, producing nearly equal implied odds across the four leading outcomes rather than strong conviction in any single value.
