Highest temperature in Munich on August 6?

Platform comparison

Market context

The key development in the last 24-48 hours is the same one traders watch every summer in southern Germany: whether Munich Airport can get a clean, hot afternoon before convection or cloud build-up caps the day’s high. At 4am UTC, the market is still effectively waiting for the daytime heating cycle, and the 0% yes probability mainly reflects that the session has not yet produced a reading near the higher temperature bands.

Munich’s August climate is usually warm rather than extreme, with an average daily high around 24.7°C and an average low around 14.1°C, while the long-run August record high at Munich is 37.0°C, set on 13 August 2003.[1] Recent August history also shows that very hot outcomes are possible but uncommon: the daily record for 6 August in the same climatology is 35.3°C, which is well above the seasonal norm and illustrates why a high-end resolution needs a genuine heat episode rather than a routine summer day.[1]

The main catalysts to watch are the actual daytime forecast for Munich Airport, especially any shift in cloud cover, humidity, rainfall risk or thunderstorm timing, because those factors can sharply limit the afternoon maximum even on otherwise warm days.[1][5][15] The settlement source is Wunderground’s Munich Airport Station history page, so traders should focus on the highest observed temperature there before the window closes rather than city-wide forecasts or nearby-station readings.[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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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%.
