Highest temperature in Taipei on July 11?

Platform comparison

Market context

Taipei Songshan Airport is currently experiencing heavy rain and typhoon conditions on 11 July 2026, with a recorded temperature of 27.8°C and a RealFeel of 87°F, making a record-breaking high impossible under these wet, cloudy skies. The 0% implied probability for any extreme heat outcome aligns with the immediate meteorological reality, as typhoons suppress temperatures significantly below the seasonal July average high of 33°C (92°F) typical for this location [1][2].

Historical data confirms that July is Taipei’s hottest month, yet typhoon interruptions regularly derail heat spikes, creating a sharp divergence between seasonal norms and actual daily peaks. On Kalshi, traders would see decimal odds reflecting this near-zero chance, whereas Polymarket displays the 0% implied probability directly, a structural difference that affects how liquidity is perceived across platforms. While Betfair and Smarkets might offer fractional odds with higher fee structures and stricter KYC requirements, Polymarket’s permissionless access allows immediate positioning on this weather event without identity verification, contrasting with the regulated gatekeeping of US-based exchanges [4].

Traders should monitor the Central Weather Administration’s hourly METAR updates for any sudden shifts in wind direction or cloud cover that might briefly clear the sky, though the forecast predicts continued heavy rain through the afternoon [8][10]. The primary catalyst remains the typhoon’s trajectory; if the system stalls or veers north, temperatures could rise slightly, but current models suggest no significant warming before the 12:00Z settlement window. Unlike Kalshi’s rigid schedule dependencies, Polymarket’s flexible resolution source via Wunderground allows for real-time data ingestion, offering a distinct advantage for weather markets where minute-by-minute changes dictate outcomes [2].
