Recent meteorological forecasts from Taiwan’s Central Weather Administration and supporting global models show Taipei on track for a daily maximum of 31°C on May 17, driving the overwhelming market consensus on that outcome. Stable subtropical high pressure, clear skies, and typical May solar heating have produced steady warming, with ensemble runs indicating little chance of significant cooling from clouds or rain. This aligns with climatological norms for mid-May, when afternoon highs commonly reach 29–32°C. While the current data strongly support 31°C as the peak, a sudden increase in convective activity or earlier sea-breeze onset could cap the temperature one degree lower and introduce limited uncertainty into the final recorded value.
