Highest temperature in Taipei on July 22?

Platform comparison

Market context

Taipei’s high temperature at Songshan Airport is the key settlement variable here, with the contract resolving to the band containing the day’s maximum recorded reading on Wunderground rather than to a broader city forecast. The cross-platform picture is already very one-sided: Polymarket prices **36°C** at **93%**, with **37°C or higher** at **5%**, while the separate sportsbook-style pricing implied by the market’s 0% yes line is far more sceptical than the exchange view, leaving a clear gap between live trading and a stale or unavailable bookmaker-style quote.[1]

That profile is consistent with a late-July Taipei heat regime, where the practical question is not whether it gets hot, but whether the airport observation reaches the next threshold above the market favourite. At 10:07 UTC, AccuWeather listed Taipei Songshan Airport as **cloudy** at **88°F**, with a **RealFeel®** of **103°** and **71% humidity**, suggesting oppressive conditions even before the local afternoon peak.[2] In this kind of setup, historical comparables usually matter less than intraday sky cover, humidity, and sea-breeze timing: a normal warm day can still settle neatly into 36°C, but a brief break in cloud and stronger insolation is what would justify the small 37°C-plus tail that the market is still assigning.[1][2]

For traders, the main catalysts are the evolving airport observation, midday cloud cover, and any nearby convective showers that could cap the maximum before the local afternoon high. Because the contract settles on the highest temperature recorded at Taipei Songshan Airport Station during the day, the meaningful watchpoints are the station’s live readings and whether conditions remain broadly cloudy or open up enough for a late spike.[2] The current market structure therefore shows strong consensus around a hot, but not extreme, outcome, with the only material divergence being between the exchange’s near-lock on 36°C and the much weaker yes probability implied elsewhere.[1]
