Recent ensemble forecasts from major models indicate a most likely maximum temperature range of 29–31°C for Taipei on October 9, driven by mostly cloudy skies, light easterly to northeasterly winds, and moderate humidity levels near 60–80% that limit strong daytime heating. This aligns with the market's emphasis on 30°C and 31°C outcomes, reflecting the central tendency and spread in numerical weather prediction runs during October's typical transition toward cooler northeast monsoon influence. Current observations on October 8 show highs near 25–27°C under similar conditions, with minimal recent shifts in steering patterns or moisture that would favor extremes above 32°C or below 28°C. Traders weigh the narrow forecast uncertainty and historical October variability around 27–30°C averages when assessing resolution thresholds.
