Highest temperature in Taipei on July 19?

Platform comparison

Market context

The market seeks to identify the highest temperature recorded at Taipei Songshan Airport on 19 July 2026, with settlement based on Wunderground historical data for that specific station. The 0% implied probability suggests traders are either absent from this market or confident the eventual reading will fall outside the range specified by the YES option—a common pattern in weather markets where the resolution brackets matter as much as the underlying forecast.

Taipei's July climate is remarkably consistent. Historical data from Songshan Airport shows daily highs in mid-July typically range between 32–35°C, with occasional peaks above 36°C during heat waves. The station's 30-year average for mid-July sits around 33°C. The current crowd probability of zero suggests either the YES bracket is positioned at an extreme (well above historical norms) or trading volume remains too thin to establish meaningful odds. Comparable July days at this station rarely exceed 37°C, making any option requiring readings in that territory a contrarian angle.

The key variable for July 2026 will be whether a Pacific typhoon system or sustained high-pressure ridge develops over Taiwan in the days preceding 19 July. Taiwan's Central Weather Administration typically issues forecasts 10–14 days ahead with reasonable confidence; traders should monitor their advisories from mid-July onwards. Recent patterns show that tropical systems can suppress temperatures whilst high-pressure systems drive them sharply upward. Settlement depends entirely on Wunderground's historical archive for Songshan, so data availability and station recording integrity are the only operational risks.
