Highest temperature in Taipei on July 10?

Platform comparison

Market context

The underlying event is the peak of summer in Taipei, where July typically delivers the year’s highest temperatures, yet a frontal system or afternoon thunderstorm forecast for 10 July 2026 is expected to cap the daily maximum below 33°C. Historical data confirms Taipei Songshan Airport’s average July high sits at 33°C (92°F), with peak summer conditions often reaching 33–35°C, but recent meteorological models indicate a sharp divergence: while long-term averages suggest a high probability of exceeding 33°C, the current weather outlook points to rain showers and heavy precipitation that will suppress temperatures to the 30–32°C range[1][4].

This 0% YES implied probability on the prediction market reflects a clear consensus among analysts that the day’s maximum will not breach 33°C, contrasting with sportsbook lines that still offer odds on higher thresholds due to historical volatility[9]. Traders should monitor the Central Weather Administration’s hourly updates for rain intensity and cloud cover, as these are the primary catalysts determining whether temperatures stay below the threshold; a recent forecast from Yr.no confirms heavy rain and a maximum of 31°C for the day, reinforcing the market’s bearish stance[7]. The key dependency is the persistence of the frontal system, which, if it weakens unexpectedly, could allow temperatures to rebound toward the historical average, though current evidence strongly supports the market’s 0% probability[3].

No moralising is needed on whether to trade; the facts show a high-confidence scenario where weather patterns align with the market’s low probability. The settlement window ending 2026-07-10T12:00:00Z will resolve based on Wunderground’s recorded high, which, given the forecast, is unlikely to exceed 32°C[9]. This case illustrates how prediction markets can outperform traditional odds by integrating real-time meteorological data, as seen in the divergence between historical averages and current forecasts[1][7].

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.
