Highest temperature in Taipei on July 13?

Platform comparison

Market context

The real-world event is the peak Celsius temperature recorded at Taipei Songshan Airport on 13 July 2026, resolved via Wunderground’s daily history for station RCSS. Programmatic traders should script a fetcher to pull the day’s maximum from the Wunderground API endpoint, parsing the JSON response for the `max_temp_c` field and comparing it against the market’s resolution ranges.

Historical data frames the current 0% YES probability as an outlier; July is Taipei’s hottest month, with an average high of 32.2°C (92°F) and a recorded low of 32.0°C on 13 July 2014 at this station[1][2]. Extreme heat spikes are common: Taipei hit 39.7°C in July 2020, the highest in 124 years, proving that temperatures can far exceed typical averages[4]. A zero probability implies the market expects no heatwave, yet climatology suggests such a stance ignores the station’s consistent July peaks.

Traders must monitor the Central Weather Administration’s 7-day apparent temperature chart and hourly forecasts for thunderstorm or cloud-cover shifts that suppress peaks[5][8]. Key dependencies include the 50% precipitation chance forecast for this afternoon and wind gusts up to 31 mph, which could cap temperatures below 37°C[5]. No official announcements are pending, but real-time Wunderground updates and CWA radar data will be the primary catalysts for re-pricing as the settlement window closes at 12:00 UTC on 13 July.
