Trader consensus around 25–27°C for Taipei’s October 6 high reflects the strengthening northeast monsoon, which has driven cooler, moister northeasterly flow across northern Taiwan after heavier rain on October 5. Official Central Weather Administration guidance and ensemble models indicate daytime maxima most likely in the mid-20s Celsius, with cloud cover, scattered showers, and sustained winds limiting afternoon warming relative to earlier October values near 30°C. Minor model spread in timing and intensity of showers creates the tight implied probabilities among 25°C, 26°C, and 27°C outcomes, while historical October climatology for Taipei centers near 27–28°C. Fresh CWA forecast updates and real-time observations tomorrow morning will refine the peak reading ahead of market resolution.
