Highest temperature in Taipei on July 11?

Platform comparison

Market context

Taipei Songshan Airport is set to record its peak daily temperature on 11 July 2026, with the market currently pricing a 0% chance for any outcome below 22°C. Historical climate data for Songshan Airport shows July highs typically reach 30°C (86°F), rarely exceeding 36°C (96°F), while current forecasts for the specific date indicate heavy rain and maximums near 28°C, which aligns with the frontrunner outcome of 29°C holding 34% implied probability [2][1][10]. The divergence between Polymarket’s decimal odds and Kalshi’s implied probability format becomes stark here; Polymarket users see 29°C at 34% probability, whereas a Kalshi-style contract would display this as roughly 1.94 decimal odds, altering how traders assess value across platforms with differing fee structures and KYC thresholds [1].

Traders must monitor the Central Weather Administration’s hourly updates, which currently report 27.8°C apparent temperature and 12mm of rain per hour as of 08:00 local time, alongside typhoon warnings moving through the region [5][7]. The settlement relies exclusively on Wunderground’s daily maximum for Taipei Songshan Airport, meaning a sudden shift from heavy rain to clear skies could spike temperatures toward the 30°C or 32°C ranges, outcomes carrying 25% and 5% probability respectively [1][8]. Unlike Betfair’s spread-based liquidity or Smarkets’ low-fee model, Polymarket’s volume concentration on 29°C ($8,132) suggests retail sentiment is anchored to wet-weather cooling, a dependency that could reverse if the typhoon stalls or veers away before midday UTC [1].
