Forecast models for Taipei on September 14 indicate a minimum temperature near 24–26°C, with trader consensus split almost evenly between those levels due to subtle differences in overnight cloud cover and shower timing. Persistent high humidity near 90% and light easterly winds limit radiative cooling, while scattered showers—expected with 60–75% probability—can either suppress or delay the daily low depending on their duration after midnight. Official guidance from regional agencies highlights typical mid-September conditions, where partial cloudiness often keeps overnight lows 1–2°C above clear-sky baselines, creating the narrow range separating the leading outcomes. Updated model runs and real-time observations overnight will likely resolve the final minimum before market settlement.
