Recent official forecasts from Taiwan's Central Weather Administration and international models indicate clear to partly cloudy conditions over Taipei on October 13, with light easterly winds and minimal precipitation supporting strong overnight radiative cooling. Minimum temperatures are projected in the 20–22°C range, though ensemble spreads and slight differences in boundary-layer moisture produce a narrow band of outcomes centered near 18–19°C. This tight clustering of market-implied odds reflects genuine uncertainty in the precise nocturnal minimum rather than any single disruptive event, with traders weighting the balance between calm high-pressure subsidence and modest northeasterly flow that could modestly elevate or suppress the low by 1–2°C. Updated model runs and local observations through the evening of October 12 remain the key near-term catalysts.
