Central Weather Administration (CWA) forecasts indicate highs of 23–29°C across northern Taiwan, including Taipei, on April 17 under partly cloudy conditions with occasional showers, anchoring trader consensus around 28–30°C outcomes where 29°C leads at 26.5% implied probability. This tight clustering stems from ensemble model agreement on persistent southerly flows and a subtropical high-pressure ridge fostering above-climatological warmth—April averages hover near 25–26°C—tempered by cloud cover variability and sea breeze influences that could suppress peaks to 28°C or allow urban heat island effects to nudge toward 30°C. Short-range forecast uncertainty remains high, with new CWA hourly updates and observational data expected throughout April 16 to refine trajectories ahead of resolution.
