**Trader consensus has converged on a 29°C high for Taipei on September 11, 2026, reflecting real-time observational data and model consensus from the Central Weather Administration and international forecasts.** Persistent cloud cover, light drizzle, and easterly flow suppressed afternoon heating below seasonal norms, keeping the peak near this threshold as confirmed by station readings and hourly updates through late afternoon. This outcome aligns with the day's steering pattern and moisture levels that limited solar insolation. A late surge above 29°C or an official revision from the primary reporting station could theoretically shift resolution, though current measurements and the proximity to day's end make such changes improbable.
