Current forecasts from regional models point to a daytime high near 32–33°C in Taipei on May 18, driven by a strengthening subtropical ridge that favors clear to partly cloudy skies and light southeasterly flow. This setup typically produces maximum temperatures 1–2°C above the May climatological mean of 29–30°C at the Songshan Airport station, with afternoon humidity around 60–70% limiting further warming. Ensemble guidance shows modest spread, with some runs favoring 31°C under slightly increased cloud cover and others allowing brief clearing that could push readings to 34°C. Traders’ near-even split between 32°C and 33°C reflects this narrow uncertainty band, while the 14.9% on 34°C or higher captures the tail risk if solar heating intensifies beyond model consensus.
