Highest temperature in Taipei on July 1?

Platform comparison

Market context

The real-world event hinges on the highest temperature recorded at Taipei Songshan Airport on 1 July 2026, measured in degrees Celsius, with settlement determined by Wunderground data. Historical patterns show Taipei’s hot season runs from 8 June to 16 September, with average daily highs exceeding 33°C (87°F) [1]. July 2025 saw highs around 27°C (80°F), while mid-July averages reach 33.8°C (92.8°F), indicating significant variability [4][6]. The current crowd-implied probability of 0% YES suggests traders expect temperatures to fall outside the market’s defined range, likely due to anticipated afternoon rain and cooler conditions forecast for today [5][7].

Traders should monitor the Central Weather Administration’s hourly updates and Wunderground’s real-time station readings, as afternoon rain could suppress peak temperatures [3][5]. Recent forecasts predict 95°F (35°C) with hot, humid conditions and afternoon rain today, a key dependency that may lower the day’s maximum [7]. Platform comparisons reveal divergences: Polymarket uses implied probability (0% YES), while Kalshi and Betfair quote decimal odds; fee structures vary from 0% on Polymarket to 2–5% on Smarkets, and KYC requirements differ, with Kalshi enforcing strict US residency checks unlike Polymarket’s global access. These structural differences shape liquidity and risk perception on this weather-specific contract.
