Persistent cloud cover, widespread showers, and thunderstorms across Taipei on June 14 are limiting solar heating and keeping the daytime maximum near 28°C according to short-range ensemble forecasts from Taiwan’s Central Weather Administration. This aligns with official guidance showing a high of 24–28°C under mostly cloudy conditions with high humidity and frequent precipitation, consistent with typical early-summer patterns in northern Taiwan where monsoon influences cap temperatures below seasonal averages around 32°C. Traders assign near-certain probability to 28°C because multiple model runs converge on this value with minimal upside risk. A sudden break in cloud cover allowing prolonged sunshine could push readings higher, though current observations and forecast consensus make that outcome unlikely before the daily maximum is recorded.
