Highest temperature in Taipei on August 2?

Platform comparison

Market context

Taipei Songshan Airport needs only a modestly warmer or cooler afternoon than forecast to move the settlement band, because this market pays out on the **highest recorded temperature** during the day rather than an average. Polymarket is currently pricing the centre of gravity at **36°C-37°C**, with 36°C at 37% and 37°C at 36%, while 38°C remains a smaller but still live tail at 12%.[1] That spread is narrow enough that a single hot burst, especially if it arrives before the day’s final observation, can matter more than the morning reading.

August is typically one of Taipei’s hottest months, with climatology and travel weather guides pointing to average highs around the low- to mid-30s Celsius and frequent humidity and rain.[4][7][9][14] On a comparable basis, that makes the current **0% YES** crowd view look more like a pricing artefact than a statement that an extreme is impossible: on prediction venues, the same underlying temperature event is usually quoted as a percentage, whereas Betfair-style exchange markets use decimal odds and Smarkets applies a commission model on winnings, so the headline price can look different even when the implied view is similar. KYC also differs materially: exchange access is broader in some jurisdictions than others, while Polymarket’s availability is more constrained by local compliance rules.

The main catalysts are the live Taipei forecast track, cloud cover and shower timing, and whether any late-afternoon heating clears before storms or sea-breeze effects cap the maximum. Polymarket’s own market notes say revisions to temperatures within the settlement window are counted until the first datapoint for the following date is published, so the exact timing of the final Wunderground update matters as much as the daytime high itself.[1] Traders comparing platforms should also remember that the settled value here is tied to the Wunderground station feed at Taipei Songshan Airport, not the city-wide forecast shown by many weather apps.[1]
