توقع: Highest temperature in London on August 4?

Platform comparison

Market context

London City Airport’s 4 August maximum will be set by how much warmth survives into the afternoon, not by the early-morning conditions now on the board. August in London is usually a low-20s Celsius month, with long-run expectations around 22°C by day and 14–15°C by night, while recent day-specific guides for 4 August cluster near 21–22°C and place England-wide recent 4 August averages around the low-20s rather than the high-20s or 30s.[1][2][3][7]

That is why a 0% yes line looks more like a reflection of the market’s range buckets than a true zero chance of a warm spike. Forecasts published late last week split the picture: some outlets saw a warm start to the week with highs around 28–31°C in London, while others had 4 August closer to 21–22°C with overcast or light-rain conditions.[3][6][13][14] For this contract, the relevant comparison is not the citywide average but the single highest reading at London City Airport Station, so even brief sunshine, wind direction and any sea-breeze effect matter more than the daily mean.[8][14]

Traders should watch for any updated morning forecast from the Met Office or other same-day services, because the key dependency is whether cloud breaks and heating arrive before the noon settlement cut-off. Rain risk is not the main issue by itself; a dry but overcast day can still cap the maximum near the low 20s, while a short sunny window can push the airport station into a higher bucket before conditions turn.[3][5][15] The main catalyst is any revised high-temperature guidance for east London between now and midday UTC, especially if later model runs keep the warm air in place longer than expected.[5][17]

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.

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.

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.
