Highest temperature in Taipei on July 22?

Platform comparison

Market context

Polymarket is pricing the Taipei Songshan Airport high for 22 July at **36°C** at **93%**, with **37°C or higher** still carrying a **5%** price, all settled in **USDC** on **Polygon** through conditional tokens. With the market resolving off the day’s recorded maximum at Taipei Songshan Airport Station on Wunderground, the current order book implies traders see a very strong chance that the peak temperature lands in the 36°C bucket rather than pushing into the next range.[1]

That pricing sits close to the recent temperature profile for Taipei, where AccuWeather is already showing a **RealFeel® of 103°** at Songshan Airport, alongside high humidity and heavy cloud cover. In practical terms, prediction-market traders usually read a 93% line as “strongly likely, but not settled”, because the only way the YES side misprices is if the day runs a touch hotter than consensus or if the station’s official maximum comes in slightly differently from the broader city forecast.[2]

For catalysts, the main watchpoints are the local daytime heating cycle, cloud break-up, rainfall, and any late shift in wind or humidity that changes how quickly temperatures climb before the Wunderground cut-off. There are no special policy or calendar announcements driving this market; the key dependency is the station’s actual daily maximum, so traders are effectively monitoring live weather updates and how the afternoon evolves against the 36°C anchor already embedded in the price.[1][2]
