Highest temperature in Munich on August 21?

Platform comparison

Market context

On 21 August 2026, the highest temperature recorded at Munich Airport Station will determine which range this contract settles into. The market currently prices all temperature bands at 0% YES, reflecting the settlement window closing at midday UTC on that date—a constraint that eliminates any meaningful trading activity once local morning observations are published. Weather Underground's Daily Observations table, not the Day High & Low summary, will serve as the authoritative source, a distinction that matters when discrepancies arise between real-time station data and rounded daily summaries.

Munich's August climate provides a baseline for interpreting this contract's current valuation. Historical data from the past two decades shows peak temperatures in late August typically range between 24–28°C, with extremes occasionally reaching 30°C during heat waves. The 0% pricing across all bands suggests traders are either absent from this market or awaiting closer proximity to the event date, when meteorological forecasts become actionable. The settlement window's early closure at noon UTC—before Munich's typical daily maximum occurs in mid-afternoon local time—creates an unusual constraint: only morning readings and any early-afternoon observations uploaded before the deadline will count.

Traders monitoring this contract should track European weather patterns in early August 2026, particularly Atlantic pressure systems and any high-pressure ridges establishing themselves over central Europe. The German Meteorological Service (Deutscher Wetterdienst) publishes extended forecasts roughly two weeks ahead; these updates typically drive liquidity shifts in weather markets. Any sustained heat advisory or extreme weather warnings for Bavaria would signal potential movement toward higher temperature bands, though the noon UTC cutoff remains the binding constraint on what data can actually settle the market.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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%.
