Highest temperature in Taipei on August 1?

Platform comparison

Market context

Polymarket is pricing this contract at **0% YES**, even though the underlying event is straightforward: what the highest recorded temperature will be at Taipei Songshan Airport on 1 August, settled in USDC through Polygon conditional tokens. That zero price suggests the market is not treating a positive outcome as realistically available right now, so any move would need fresh information to change the order book before the settlement window closes.

The historical frame is still useful. Taipei’s August climate is typically hot and humid, with forecast and guide data pointing to daily highs around the low-to-mid 30s °C, and occasional spikes higher; one reference notes Taipei’s August highs often reach 34–37°C, while another records a 38°C August high in the past decade.[2][10][17] Polymarket’s own pricing history on this event has also shown traders clustering around the mid-30s, with 36°C and 37°C the leading buckets in its live market view, which is a more normal-looking distribution than a 0% headline suggests.[4]

For a trader, the main catalysts are the latest Taipei forecast updates, especially whether the Central Weather Administration or international ensemble guidance shifts towards a hotter or cooler peak during the day. Afternoon thunderstorms, typhoon-related cloud cover, and urban heat effects can all move the realised high at Songshan Airport, so the relevant watchlist is not abstract “August weather” but the intraday temperature trajectory and any rain or storm timing that suppresses the day’s maximum.[12][17] On Polymarket, that information feeds straight into the USDC-denominated conditional token price until the official Wunderground reading is locked in.
