Highest temperature in Taipei on August 7?

Platform comparison

Market context

Polymarket prices this Taipei heat contract at **0% YES** right now, even though the underlying benchmark is the highest Celsius reading at Taipei Songshan Airport on 7 August, settled from Weather Underground’s Daily Observations table rather than the summary high-and-low panel.[3] That setup matters for traders because the market is not paying on “what the app says” in broad terms; it pays on the exact observed peak in the station record, and the winning outcome is whichever temperature band captures that reading in the final data.[3]

The broader weather backdrop does not point to an extreme outlier. August climate guides for Taipei consistently describe hot, humid conditions, with typical highs around 32–36°C and occasional peaks into the mid-to-high 30s Celsius.[2][5][12] AccuWeather’s August forecast for Taipei City shows daily highs mostly in the mid-to-high 80s Fahrenheit, roughly 30–34°C, which fits a warm but not obviously exceptional day.[1] The market’s current pricing also sits against a recent precedent: another Taipei temperature market on 5 August resolved to 37°C, showing that late-day spikes can and do matter when traders are marking to the station record rather than the forecast headline.[20]

For a Polymarket user, the practical catalysts are the final station observations on Weather Underground and any late revision or anomaly in the Taipei Songshan Airport feed before settlement.[3] The contract runs on Polygon and settles through conditional tokens, so the on-chain outcome is fixed by the data source, not by consensus in the chat or by the day’s advertised forecast.[3] Traders will typically watch the Central Weather Administration forecast cadence, local cloud cover, rainfall timing, and whether afternoon convection suppresses or boosts the peak reading, because those factors drive the last few degrees that decide the band.[15]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
