Highest temperature in Taipei on July 13?

Platform comparison

Market context

Taipei Songshan Airport is set to record its peak daily temperature for 13 July 2026, with the settlement depending on the highest Celsius reading at the station by midday UTC. Historical data frames the current 0% crowd-implied probability as an outlier; July is the hottest month locally, averaging a high of 92°F (33°C), and the station recorded a low of 32°C on 13 July 2014, while all-time records for the city have reached 39.7°C [1][2][6]. Such extreme heat is typical for mid-summer in the capital, making a zero-probability stance on any significant temperature range appear disconnected from seasonal norms.

Traders should monitor real-time radar and hourly forecasts from the Central Weather Administration, which currently indicate a chance of thunderstorms and moderate precipitation that could suppress peak temperatures [7][9]. The specific catalyst is the 13 July hourly chart showing a maximum forecast of 31°C with 5.6 mm of rain, a condition that would likely keep temperatures well below historical highs [10]. While sportsbooks and other prediction platforms often align on weather outcomes, the divergence here between the 0% implied probability and the 31°C forecast suggests a potential mispricing relative to the analyst consensus on immediate atmospheric conditions.
