Highest temperature in Munich on August 21?

Platform comparison

Market context

Munich's weather on 21 August 2026 will determine which temperature band captures the day's peak, measured at Munich Airport Station and sourced from Weather Underground's Daily Observations table rather than summary figures. The settlement window closes at midday UTC, meaning the highest temperature recorded up to that point becomes the resolution metric. For automated traders, this creates a specific data-fetch requirement: the Daily Observations granular dataset rather than the rounded Day High & Low display, which occasionally diverges by 0.5–1.0°C depending on observation timing and rounding protocols.

Historical August temperatures at Munich Airport show a median high of 24–26°C, with extremes ranging from 19°C in cooler years to 34°C during heat waves. The current 0% crowd probability suggests either extreme confidence in a narrow band below the market's lowest threshold or insufficient liquidity to establish meaningful pricing. Comparable European airport stations demonstrate that late-summer forecasting accuracy degrades significantly beyond ten days; traders relying on seasonal models rather than updated meteorological data typically misread probability distributions by 8–12 percentage points.

Traders should monitor European weather pattern shifts in early August 2026, particularly Atlantic ridge positioning and any heat dome development over central Europe. The German Meteorological Service (Deutscher Wetterdienst) publishes extended forecasts fortnightly; these updates typically shift market odds 2–4 weeks before settlement. For programmatic approaches, setting conditional orders tied to DWD forecast releases or anomaly thresholds in upper-air temperature data would capture volatility spikes more efficiently than manual monitoring.

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%.
