Recent strengthening of the northeast monsoon has introduced cooler northeasterly flow and elevated moisture over northern Taiwan, driving trader focus on overnight radiative cooling under variable cloud cover for Taipei’s October 7 minimum. Official Central Weather Administration guidance and ensemble forecasts consistently point to lows near 20–22 °C amid partly cloudy skies, with limited potential for stronger cooling if winds weaken or clearer conditions develop. This positions mid-20s outcomes as favored while the low probability attached to 17 °C or below reflects the unlikelihood of deeper cold-air advection this early in the season. Updated model runs and CWA briefings over the next 48 hours will refine wind and cloud trends ahead of resolution.
