Recent numerical weather prediction models from the China Meteorological Administration point to a daily maximum of 26–27 °C in Chongqing on May 19, with the market’s narrow lead for 27 °C (28.0 %) reflecting modest model consensus on boundary-layer mixing and limited afternoon cloud cover. Southerly flow is expected to supply sufficient warmth for daytime heating, yet light precipitation and high humidity typical of the region’s May climatology may cap the peak one degree lower. The long-term average high of approximately 27 °C provides useful context, while traders continue to watch overnight ensemble runs for any shifts in steering patterns or rainfall timing that could alter the exact maximum recorded at official stations.
