Recent forecasts indicate the strengthening northeast monsoon will begin influencing northern Taiwan on October 1, introducing cooler northeasterly flow, increased cloud cover, and scattered showers that limit nighttime radiative cooling and moderate minimum temperatures. Official guidance from Taiwan's Central Weather Administration projects overnight lows in the 23–27°C range amid this transition from late-summer heat, while numerical models show modest spread due to timing of frontal passage and precipitation efficiency. Market-implied probabilities clustered near 26°C and 30°C+ reflect trader assessment of these variables, with lower outcomes gaining traction only if monsoon effects arrive earlier or rainfall enhances evaporative cooling. Updated short-range model runs and observational data over the next 48 hours will refine the exact minimum.
