Highest temperature in London on August 1?

Platform comparison

Market context

London’s outcome is the **highest temperature recorded at London City Airport** on 1 August, not the citywide maximum, so the key question is how warm that specific station gets during the day. The market is currently pricing **26°C** as the most likely reading, with **25°C** and **27°C** next in line, which fits the usual summer range for London rather than an extreme heat event.[1][4]

That pricing is easier to read against London’s August climatology. Long-run averages put London’s August daytime highs around the low-20s Celsius, while early August is often warm enough for upper-20s readings without requiring a full heatwave.[4][10] The market is also consistent with the fact that London can run a little hotter or cooler than the airport depending on cloud cover, wind, and the urban heat-island effect, so a one-degree spread around the modal forecast is common when traders are anchoring on a near-normal summer day.[1][4]

For traders, the main catalyst is any late change in the short-range forecast from the Met Office or other model updates, especially if sunny spells persist long enough to push the airport station from 25–26°C into 27°C territory.[1][13] The relevant dependency is timing: the market resolves on the day’s highest reading at the station, and revisions are only considered until the first datapoint for the following date is published, so any late evening update or rapid post-peak weather shift would matter less than the actual daytime maximum.[1]

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.

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?

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.
