**Forecast models for Taipei on October 15 point to a high near 27–28°C under easterly flow and mostly cloudy skies.** Persistent moderate easterly winds, combined with 40–60% cloud cover and light moisture, limit surface heating while keeping humidity elevated around 70%. Official and ensemble guidance shows minimal diurnal warming potential, with afternoon temperatures capped by the stable airmass and lack of strong subsidence or clear-sky conditions that would push readings to 30°C or higher. Traders assign the highest probabilities to 28°C and 29°C because recent model runs cluster in this narrow range, reflecting uncertainty in exact cloud timing and boundary-layer mixing rather than any major synoptic shift. A modest uptick in clearing or reduced wind speeds could nudge the maximum to 29°C, while thicker cloud decks or earlier showers would favor 27°C or below. No significant tropical or monsoon influences are expected to alter the pattern before resolution.
