Traders see the tight clustering around 24–25°C as the most probable peak for Chongqing on June 29 because short-range models currently indicate a modest subtropical high-pressure ridge over the Sichuan Basin, with daytime heating tempered by high humidity, scattered cloud cover, and possible light showers. These conditions typically cap maximum temperatures near the climatological late-June average of 28–30°C but can suppress readings by 3–5°C when low-level moisture and orographic lifting from surrounding terrain enhance convection. Recent model consensus from agencies such as the China Meteorological Administration shows limited day-to-day shifts, keeping the distribution narrow; however, small differences in simulated cloud timing or wind direction can still swing the daily high between 23°C and 26°C. The market’s spread across these brackets therefore reflects genuine forecast uncertainty rather than strong conviction in any single outcome, with resolution hinging on the final 48-hour model updates and observational data from local stations.
