Highest temperature in Taipei on July 10?

Platform comparison

Market context

The real-world event centres on the highest temperature recorded at Taipei Songshan Airport on 10 July 2026, with settlement determined by Wunderground’s daily maximum in degrees Celsius. Historical data shows July is Taipei’s hottest month, averaging a high of 92°F (33.3°C) at Songshan, while June highs climb from 85°F to 91°F [1][4]. Current conditions on 10 July 2026 show 91°F with 66% humidity and heavy cloud cover, yet forecasts for the same date in prior years indicate peaks near 95°F under sunny skies [2][5]. The crowd-implied 0% probability for any specific range suggests traders view the outcome as too uncertain or the market as illiquid, a divergence from platforms like Kalshi that use implied probability versus Polymarket’s decimal odds, and from Betfair’s fee structures which often undercut Smarkets’ lower commissions on similar weather contracts.

Traders should monitor the Central Weather Administration’s hourly updates for Taipei Songshan, particularly wind direction shifts from east to northeast and cloud cover changes that could suppress peak temperatures [7]. A recent 10-day forecast for Taipei indicates 99% rain chance on 10 July with highs capped at 87°F, contrasting with sunny-day peaks of 95°F [5]. Key dependencies include the timing of afternoon thunderstorms and UV index levels, which reached 11 in prior July forecasts, potentially limiting heat accumulation if precipitation occurs [3]. The settlement window ending 12:00 UTC on 10 July 2026 means any late-morning rain could decisively lower the maximum, a factor platforms like Polymarket may price differently than Kalshi due to their distinct liquidity models and KYC requirements for US traders.
