The Central Weather Administration's latest forecast, updated April 16, projects a daytime high near 30°C in Taipei on April 17 under partly clear skies with isolated showers and mostly cloudy periods overnight, driving closely matched market-implied probabilities for 28°C (22.5%) and 29°C (21.5%) over 30°C (16.0%). Trader sentiment reflects uncertainty in cloud cover extent, which could reduce solar insolation and cap peak afternoon heating despite urban heat island effects boosting temperatures above rural baselines; sea breezes may further moderate highs. Today's observed high of 30°C provides precedent, but April climatology averages 26°C with variable insolation. Watch evening CWA updates and tomorrow's hourly observations for shifts, as short-range model ensembles show minor divergences.
