Highest temperature in Taipei on August 8?

Platform comparison

Market context

Taipei is starting the day with **heavy rain and overcast conditions** in the live forecasts, which is a material change from the hotter, clearer August pattern that usually leaves room for a sharp daytime climb if the rain breaks later on.[7][9] AccuWeather’s Taipei outlook shows around 90°F / 80°F for today, while Timeanddate also points to very wet, unsettled conditions with a 99% chance of rain and a daytime high near 88°F, suggesting that the ceiling for the afternoon temperature may be constrained unless cloud cover thins quickly.[7][9]

For context, Taipei’s August climatology is hot and humid, with typical highs around 30–34°C, but the city can still spike well above that when sunshine dominates and winds are light.[3][8][13][15] The key historical reference for this market is the 39.3°C reading recorded on 8 August 2013, which remains Taipei’s benchmark for extreme heat and shows that the date has produced outsized highs before.[2][4] By contrast, the 0% crowd-implied probability looks consistent with a market that is treating a top-end temperature band as unlikely under today’s wet setup, rather than ruling out the possibility of a warm early or mid-afternoon reading.

Traders should watch the timing of Taipei’s rain bands, any late-morning clearing, and whether the official station at Taipei Songshan Airport gets a short window of solar heating before the settlement cut-off.[7][9][20] Because the market resolves to the **highest** value in Weather Underground’s Daily Observations table, even a brief spike matters more than the forecast high shown elsewhere.[20] The practical catalyst is whether the day turns from persistent downpours to broken cloud in time for the station to log a sharper midday peak; if not, the realised maximum is more likely to stay near the lower end of the August range than to approach record territory.[7][9]

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 Prediction Today, 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.

UK Frequently Asked Questions

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.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
