Highest temperature in Taipei on July 19?

Platform comparison

Market context

On 19 July 2026, the highest temperature recorded at Taipei Songshan Airport will settle this market into one of several temperature bands. The settlement hinges on a single daily maximum reading from Wunderground's historical database for that station, which serves as Taiwan's primary urban weather observation point. The current 0% implied probability suggests traders are either awaiting data entry or treating the market as inactive pending the settlement window.

Taipei's July climate is consistently hot and humid, with historical daily maxima typically ranging between 32–36°C. Over the past decade, extreme heat days above 37°C have occurred roughly once per summer season, whilst readings below 31°C are rare in mid-July. The absence of trading activity here contrasts sharply with comparable weather markets on Kalshi or Betfair, where similar Asian temperature contracts attract modest but steady volume. Polymarket's fee structure (2% maker/taker) and KYC requirements differ from Kalshi's regulated US-focused approach, which may explain why this Taiwan-specific contract shows minimal engagement relative to US-based weather derivatives.

Traders monitoring this market should track the Taiwan Central Weather Administration's seasonal forecasts and any El Niño or heat-dome announcements affecting East Asia in early July 2026. Wunderground's data-entry lag—typically 24–48 hours post-settlement window—means resolution may be delayed beyond the 12:00 UTC deadline. Cross-referencing with Taiwan's official meteorological records will be essential for dispute resolution, particularly if the station experiences equipment downtime or data gaps on the settlement date.
