Pronóstico: Highest temperature in London on August 14?

Platform comparison

Market context

The market resolves on the highest temperature recorded at London City Airport on 14 August 2026, using the Daily Observations table from Weather Underground as the authoritative source. This specific station and data hierarchy matter for settlement, as discrepancies between summary and detailed observation records have historically caused disputes in weather markets.

London's August temperatures typically range between 20–27°C, though extremes do occur. The city recorded 40.3°C on 19 July 2022 during an exceptional heatwave, and 36.4°C on 25 July 2019. August averages sit lower than July, with the warmest days usually clustering in the first fortnight. Historical data from the Met Office shows that temperatures exceeding 30°C in mid-August happen roughly once every three to four years in London, whilst readings above 35°C remain rare events confined to perhaps one summer per decade.

Traders should monitor long-range weather models from late July onwards, particularly the North Atlantic Oscillation and jet stream positioning, which determine whether continental heat systems can reach the British Isles. The UK Met Office typically issues extended forecasts by early August. Any significant atmospheric pattern shifts—such as a blocking high-pressure system establishing over Scandinavia—would be the primary catalyst for material temperature moves. The current 0% probability reflects typical August conditions; material shifts would require forecasts indicating anomalous heat well before the settlement window closes.

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.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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.
