Highest temperature in Taipei on July 12?

Platform comparison

Market context

Taipei Songshan Airport is currently recording cloudy conditions with a maximum temperature of 32°C (90°F) as the day progresses, yet the market assigns zero probability to any temperature range exceeding this threshold. This 0% YES implied probability reflects a sudden shift in the last 24 hours where forecast models converged on a stable, cloud-covered pattern that suppresses peak heating, contrasting sharply with the typical clear-sky intensity expected in mid-July.

Historical data frames this current pricing as an outlier rather than a baseline expectation, as July is statistically the hottest month with average highs near 35°C (92°F) and temperatures rarely dipping below 26°C or exceeding 36°C (96°F) [2]. Comparable cases from previous years show that when cloud cover persists through the afternoon, peak temperatures often stall near 31–32°C, but the market’s absolute dismissal of higher ranges ignores the volatility inherent in late-summer heatwaves where sudden clearing can push readings toward 37°C within hours.

Traders must monitor the Central Weather Administration’s hourly updates for any break in the cloud layer, as the current 88% relative humidity and 0.0mm rain-of-hour reading suggest a stable atmosphere that could rapidly destabilise if wind patterns shift [6]. The primary catalyst is the scheduled 15:00 local forecast release, which will determine if the afternoon remains cloudy or clears to allow solar heating; Wunderground’s final settlement will depend entirely on whether this afternoon window delivers the typical July heat spike or maintains the current suppressed profile [7].

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today 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.
