Official forecasts from Taiwan's Central Weather Administration and ensemble models indicate a likely daily maximum near 29–30 °C in Taipei on June 16, with widespread cloud cover, showers, and isolated thunderstorms expected to limit solar heating. This pattern stems from moderate monsoon flow and modest instability that has kept recent daytime highs slightly below the June climatological average of 31–33 °C. Trader sentiment clusters on these two outcomes because short-range guidance shows little model spread outside 27–31 °C, while any break in cloudiness or delayed rainfall could briefly allow readings near 31 °C. Updated model runs and the Central Weather Administration’s morning briefing on June 15 remain the key near-term catalysts.
