Highest temperature in Taipei on July 12?

Platform comparison

Market context

Taipei Songshan Airport is currently overcast with heavy rain expected, suppressing any chance of extreme heat on 12 July 2026. The market prices the “YES” outcome at 0%, reflecting the immediate reality that precipitation and cloud cover will prevent temperatures from reaching the thresholds required for a high-heat resolution.

Historically, July is Taipei’s hottest month, with an average high of 92°F (33.3°C) at Songshan, yet wet-season thunderstorms frequently cap daily peaks well below 35°C[3]. In comparable wet-weather scenarios, recorded highs have clustered around 30–32°C, making outcomes above 34°C improbable when rain is active. The current 37% probability for 34°C and 29% for 35°C on Polymarket aligns with this pattern, while the 96% consensus for 37°C on the adjacent July 12 contract appears mispriced given today’s conditions[1].

Traders should monitor the Central Weather Administration’s hourly METAR updates for RCSS, which currently show 29°C temperature, 88% humidity, and zero rainfall per hour[8]. The key catalyst is whether the predicted heavy precipitation (>0.8") materialises and persists through midday, as sustained rain would lock temperatures below 33°C[6]. Settlement depends entirely on Wunderground’s published daily maximum for RCSS, so real-time METAR data is the primary on-chain dependency for recalibrating conditional token positions in USDC on Polygon.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.
