Recent northeast monsoon conditions over Taiwan have introduced cooler, more humid maritime air and enhanced cloud cover across northern regions, including Taipei, suppressing peak daytime heating on October 10. Official forecasts from sources like the Central Weather Administration and numerical models indicate a maximum temperature most likely in the 25–27°C range amid scattered showers and easterly winds, though localized variations in urban heat or brief clearing could push readings to 28–29°C. This atmospheric setup explains the market's tight clustering around 28–30°C outcomes, with 29°C holding the highest implied probability as traders weigh model consensus against historical October baselines near 28°C and the potential for modest forecast revisions before resolution.
