Recent forecasts from Taiwan's Central Weather Administration and global models indicate overnight lows in Taipei on September 16 settling near 22–23°C under partly cloudy skies and moderate northeasterly winds. These conditions, typical for mid-September transitional weather without active tropical systems, support the tight clustering of market-implied odds around 22–24°C. Minor differences in model timing for the daily minimum, urban heat island effects, and precise wind patterns create the narrow spread in trader sentiment. Updated model runs and official station observations through the evening will likely resolve remaining uncertainty before market close.
