Recent ensemble forecasts for Chongqing on May 18 cluster daily maximum temperatures around 23–25 °C, aligning with the market’s closely matched leading contracts at 24 °C, 23 °C, and 25 °C. Mid-May climatology in the Sichuan Basin features persistent low-level moisture and moderate subtropical high pressure that caps afternoon heating, while variable cloud cover and light southerly flow create small differences in boundary-layer mixing that determine whether readings settle at the lower or upper end of this narrow range. Historical May averages near 24 °C provide additional context for the current trader consensus, with resolution hinging on the official China Meteorological Administration observation at the primary station.
