**Current forecasts for Chengdu on August 27, 2026, cluster daily minimum temperatures in the 24–26°C range, producing the tight distribution of market-implied probabilities around 23–26°C.** Multiple sources, including timeanddate, TravelChinaGuide, and local reporting, show overnight lows near 24–26°C under partly cloudy to overcast conditions with isolated thunderstorms possible, limiting nocturnal radiative cooling in the humid subtropical environment. The Sichuan Basin’s topography and high summer humidity (often 70–90%) reduce the typical diurnal temperature range, while urban effects and variable cloud cover or light winds create small but decision-relevant differences in the recorded minimum. Recent model consensus has held steady over the past 48 hours, with no major shifts from incoming high-pressure influences or monsoon moisture. Traders are pricing genuine uncertainty in exact timing of any clearing or precipitation, as ensemble spreads in short-range forecasts commonly span 2–3°C for overnight lows. Official Chinese Meteorological Administration observations and final verification will resolve the market once the calendar day ends in local time.
