Highest temperature in Taipei on July 31?

Platform comparison

Market context

Polymarket is pricing this contract at **0% YES** right now, so the market is effectively saying there is no credible chance of a Taipei Songshan Airport Station high landing in the specified range before settlement closes. On Polymarket, shares trade in **USDC** on **Polygon**, with the contract ultimately paying out through conditional tokens tied to the Wunderground reading for the day’s highest temperature at the station.

For context, Taipei is in a hot stretch. Focus Taiwan reported that the Central Weather Administration issued an orange heat advisory for Taipei on Friday after daytime temperatures topped **36°C** for a third straight day, which is materially above the sort of midsummer highs usually seen in the city.[1] That said, the market settles on the single highest observation recorded at Songshan Airport Station on 31 July, not on a citywide average, so brief spikes, local cloud cover, and sea-breeze effects matter more than broad seasonal norms. Forecast pages for Taipei on 31 July also point to another very warm day, with AccuWeather showing highs around **90°F** and Weather2Travel citing a typical July daytime maximum of **32°C**.[2][11]

Traders should watch the afternoon forecast cycle, any CWA heat or rain advisories, and the timing of the day’s peak temperature at the airport station, because a late spike can still change the settlement range. The main dependency is the Wunderground station history page for Taipei Songshan Airport, which resolves the market using the highest temperature recorded on the day, so the relevant catalyst is not an official noon reading but the final intraday maximum before the cutoff.[1][2]

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
