توقع: Highest temperature in London on August 19?

Platform comparison

Market context

The market concerns the highest temperature recorded at London City Airport on 19 August 2026, with resolution determined by the Daily Observations table on Weather Underground rather than summary figures. The settlement window closes at midday on that date, meaning afternoon temperature spikes after noon will not factor into the outcome.

London's August temperatures have historically clustered between 20–26°C, with extremes rare but not unprecedented. The city recorded 40.3°C in July 2022 during an exceptional heatwave, though August typically sees slightly lower peaks. Over the past decade, August highs at London City Airport have exceeded 28°C on fewer than three occasions, with most years settling in the 22–25°C range. The 0% crowd probability suggests traders are pricing in a scenario where temperatures remain well below any upper threshold the market may have defined, reflecting baseline seasonal expectations.

Catalysts affecting August 2026 temperatures include Atlantic weather patterns, jet stream positioning, and any developing high-pressure systems across northern Europe in the weeks preceding the date. The UK Met Office's seasonal outlooks, typically issued in July, will provide guidance on whether conditions favour above or below-average warmth. Traders should monitor late July forecasts from established meteorological services, as these will sharpen probability estimates closer to the settlement window. Any significant deviation from typical August conditions—such as a continental air mass pushing northward—would shift expectations materially.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
