Highest temperature in Taipei on July 22?

Platform comparison

Market context

Taipei Songshan Airport is in a hot midsummer pattern, and the live weather feed already shows very warm conditions: 88°F with a RealFeel of 103°F, high humidity and only light winds. That keeps the day in range for a late-afternoon peak, but the market settles on the *highest* reading recorded at the station by the cutoff, so brief cloud breaks or afternoon heating matter more than the morning temperature itself.[1][3]

Historically, July is Taipei’s hottest month, with average highs around 34°C and daily values often clustering close to that level; a cited local guide also notes the city’s record heat has reached 39.3°C. Against that backdrop, a current 0% yes price on the lower bands should be read as a view that the day will finish in the upper 30s Celsius rather than merely “hot”, which aligns with Polymarket’s 93% for 36°C and only 5% for 37°C or higher.[4][2]

For traders comparing venues, the underlying event is the same, but the presentation differs: Polymarket shows outcome probabilities directly, while Kalshi and many sportsbook-style books quote prices in their own formats, often with fees and a tighter set of account requirements. That matters here because the settlement source is fixed to Wunderground for Taipei Songshan Airport, so the main catalyst is simply how the afternoon temperature evolves before the local day ends; any late cloud cover, sea-breeze shift or shower could trim the peak, although no major weather warning is flagged in the sources provided.[3][1]
