Highest temperature in Taipei on July 22?

Platform comparison

Market context

Polymarket is pricing the Taipei Songshan Airport reading very heavily towards the lower end of the summer range, with **36°C** the clear frontrunner at **93%** and **37°C or higher** down at **5%**[1]. For a trader posting USDC on Polygon, that means the conditional tokens are already implying that the day’s peak at RCSS is expected to stay below the hotter bins, even though the contract settles off the Wunderground daily maximum for the station rather than a city-wide average[1][4].

That current shape is consistent with Taipei’s July climatology, where daytime highs are commonly described as sitting around **32–38°C** and humidity makes conditions feel hotter than the thermometer suggests[3]. Songshan is a low-lying urban airport station, so small shifts in cloud cover, sea-breeze timing, or afternoon convection can matter more than the broader city narrative; on markets like this, the range bins often trade around whether the day can squeeze past the mid-30s, rather than around any dramatic heat spike.

For live catalysts, the key watchpoint is the actual temperature trace through the afternoon and early evening local time, because settlement uses the **highest recorded** value for the full day at Taipei Songshan Airport Station on Wunderground[1][4]. The current observed conditions already show very hot weather in Taipei, with a **103°F RealFeel** reported at Songshan, but that is not the settlement measure; what matters is whether the station’s official daily maximum reaches the next bracket before the window closes[2][1].
