Highest temperature in Taipei on July 6?

Platform comparison

Market context

The 0% YES probability for Taipei’s highest temperature on 6 July 2026 reflects a sudden shift in short-term forecasts: heavy rain and saturated air have dominated the last 24 hours, suppressing daytime highs well below the ranges needed to trigger a “yes” outcome. Current conditions at Songshan Airport show 100% humidity, light rain, and winds of 44km/h, which will continue to limit solar heating and keep temperatures near 13°C this morning—far from the 30°C+ thresholds typical for midsummer peaks[3].

Historically, July in Taipei sees average highs of 29.9°C to 30°C (85.8°F–86°F) in the first ten days, with Songshan Airport’s hottest month averaging 92°F[4][5]. Yet the current 0% probability aligns with comparable cases where persistent cloud cover and rain in early July have repeatedly capped highs below 28°C, making extreme heat events unlikely unless a sudden dry spell or typhoon-induced clearing occurs.

Traders should monitor the Central Weather Administration’s hourly updates for any forecast revisions indicating reduced cloud cover or rising dew points, as these are the primary catalysts for temperature spikes[6]. A recent AccuWeather forecast confirms July highs typically reach 86°F–96°F, but only if rain subsides; until the rain stops and humidity drops, the market’s 0% stance remains grounded in real-time meteorological data[2].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
