Recent forecast models from agencies including the China Meteorological Administration and international numerical weather prediction systems indicate a minimum temperature near 23°C for Wuhan on September 13 under mostly clear skies, light northerly winds, and stable high pressure, consistent with the ongoing warm late-summer pattern. Trader consensus placing 19°C as the leading outcome at 56% implied probability appears driven by uncertainty in precise urban station readings, potential for localized cooling from increased humidity or brief cloud cover, and historical September variability where overnight lows can dip 2–4°C below daytime guidance. The 44.5% on 15°C or below and 44% on 18°C reflect hedging around model spread and any late revisions to steering patterns, while probabilities drop sharply above 20°C given the absence of stronger cold air advection in current guidance. Key upcoming data include updated evening model runs and official minimum observations from the Wuhan meteorological station.
