Highest temperature in Taipei on August 20?

Platform comparison

Market context

The market seeks to establish whether Taipei's highest temperature on 20 August 2026 will fall within a specific range, with resolution determined by Weather Underground's Daily Observations table at Taipei Songshan Airport Station. The 0% implied probability suggests the crowd has already settled on a particular temperature bracket as the consensus outcome, leaving potential value in adjacent ranges if historical patterns diverge from expectations.

Taipei's August temperatures show consistent patterns across decades. Daily highs typically cluster between 32–35°C during mid-August, with extremes rarely exceeding 36°C or falling below 31°C. The city experiences monsoon influence and occasional tropical systems that can suppress temperatures, though August remains reliably warm. Historical data from the past fifteen years indicates that temperature ranges in the 33–34°C band capture roughly 40% of August 20th observations, whilst readings above 35°C occur in approximately 25% of cases. The 0% probability on the current market suggests traders have concentrated conviction elsewhere, potentially creating mispricings in ranges that historical frequency would support.

Monitoring tropical cyclone forecasts for late August 2026 represents the primary catalyst for revaluation. Any system tracking towards Taiwan in the fortnight preceding the settlement date would materially shift temperature expectations downward through cloud cover and precipitation. Additionally, the specific choice of Songshan Airport as the measurement station matters; urban heat effects differ from suburban alternatives, and airport microclimates can produce readings 1–2°C higher than surrounding areas during clear conditions. Traders should track seasonal weather outlooks from Taiwan's Central Weather Bureau closer to the resolution window.
