Recent short-range forecast guidance from the Central Weather Administration points to a peak temperature near 33–34 °C in Taipei on July 13, consistent with the market’s tight clustering around those outcomes. In Taipei’s subtropical climate, maximum readings are shaped by the strength of the East Asian monsoon flow, afternoon convective cloud cover that limits insolation, and urban heat-island effects at official measurement sites. Minor model differences in the timing or coverage of showers, boundary-layer moisture, and steering winds can shift the daily high by 1–2 °C, producing the observed spread across 32–35 °C bins. Updated model runs and afternoon observations over the next 48 hours will provide the clearest signal ahead of market resolution.
