Trader consensus on the 22°C outcome for Taipei’s lowest temperature on September 8 reflects real-time observational data and forecast consensus from Taiwan’s Central Weather Administration, showing overnight lows stabilizing near 22°C amid partly cloudy conditions, light easterly winds, and high humidity near 90% that limited radiational cooling. Multiple meteorological models converged on this minimum without significant divergence, consistent with typical early-September climatology for the region where diurnal ranges narrow under moist subtropical air masses. The near-100% implied probability indicates strong alignment between surface observations, dew-point trends, and short-range guidance, leaving minimal room for revision before official daily records close. Unlikely challengers include a sudden clear-sky window or localized wind shift enabling extra cooling below 21°C, though current atmospheric stability makes such shifts improbable.
