Official forecasts from Taiwan's Central Weather Administration and international models indicate a daily maximum of 29°C in Taipei today, with afternoon peaks limited by cloud cover, thundershowers, and typical June humidity. This consensus, backed by real-time observations and model agreement, drives the market's 100% implied probability on 29°C. Historical climatology for mid-June shows averages near 31°C, but recent atmospheric conditions including moisture and steering patterns have suppressed highs. Late-day measurements or minor urban heat effects could theoretically push readings to 30°C, though current data and resolution criteria make such shifts improbable before markets close.
