**Trader consensus on a 32°C high for Taipei on September 17 reflects late-day observational data and model consensus from regional forecasts showing a peak near that threshold.** Persistent northeasterly flow, high humidity around 70-85%, and scattered cloud cover limited further diurnal heating after midday readings approached 32°C, aligning with climatological September averages of 30-33°C in northern Taiwan. Official monitoring confirms no significant deviation from these conditions through the evening. A realistic challenge would require an unexpected late surge in insolation or model bias in temperature verification, though the market's near-certainty indicates strong alignment between current readings and resolution criteria.
