Highest temperature in London on August 1?

Platform comparison

Market context

London’s highest temperature on 1 August will be set by the day’s peak reading at London City Airport, with the market resolving only after the Wunderground daily record is finalised. The current 0% yes price implies traders see an extremely low chance of an outcome in the market’s defined range, but the historical backdrop does not support treating early zeros as meaningful in weather markets when the relevant date has not yet played out.[2][3]

For context, London is usually warm rather than hot at the start of August: WeatherSpark says 1 August typically sits between about 60°F and 74°F, which is roughly 16°C to 23°C.[1] City-centre and airport stations can still spike above that band during short-lived heat surges, and London’s August record highs have reached the high 30s Celsius in past years, including 38.1°C at Kew Gardens on 10 August 2003 and 36.4°C at Heathrow on 31 July 2020.[7][8][13]

The main catalysts for traders are the day’s synoptic setup and how much warmth survives into the afternoon over east London, where urban heat and light winds can matter more than the broad city average. The market’s resolution also depends on the final Wunderground data publication, because revisions made before the first reading for the following day are still counted.[2][3]

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?

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
