Trader sentiment clusters tightly around 27–30°C outcomes for Taipei's highest temperature on May 17, reflecting Central Weather Administration (CWA) forecasts showing a daytime high of 21–29°C under partly cloudy to mostly clear skies, up from mid-week showers that capped May 15 at 22–26°C. This warming trend stems from a subtropical high-pressure ridge promoting subsidence and reduced cloud cover, though model ensembles diverge on peak intensity due to sea breeze influences and urban heat effects at Songshan Airport station. Probabilities differentiate by nuanced factors: 27–28°C if afternoon onshore flows moderate peaks, versus 29–30°C under sustained clear conditions; extremes remain unlikely absent unusual advection. Watch CWA's next update for refined guidance.
