Forecast models from sources like ECMWF and GFS indicate a highest temperature in Taipei on September 13 most likely reaching 33–34°C under easterly flow, partly cloudy skies, and high humidity typical of late-summer conditions. Stable high pressure and light winds limit cooling overnight while daytime heating supports afternoon peaks near these levels, consistent with seasonal baselines around 31–33°C. Recent model runs show minimal disagreement, with some guidance edging toward 35°C if cloud cover remains low, though showers or increased moisture could cap readings at 32–33°C. Market-implied odds reflect this narrow range, with 34°C as the consensus outcome ahead of official Central Weather Administration data and any last-minute forecast shifts.
