Highest temperature in London on July 13?

Platform comparison

Market context

London City Airport is currently experiencing a high of 24°C on 13 July 2026, with humidity at 94% and falling pressure, conditions that make a significant temperature spike unlikely before the settlement window closes at noon UTC [4][6]. The market’s 5% YES probability for a higher outcome reflects the immediate reality that the day’s peak has likely already been reached or is capped by the current overcast, southerly flow and high moisture content, which suppress further heating [6][7].

Historically, July is London’s hottest month with an average high of 22°C (72°F), but extreme spikes are rare and usually tied to specific heatwave events like the 40.2°C record set at Heathrow in July 2022 [1][5]. That record, however, occurred at a different station under distinct atmospheric conditions; London City Airport, situated in a more urban, river-adjacent location, typically records lower peaks than Heathrow, and recent July maxima here have clustered around 27–29°C, making a break above that threshold without a clear heatwave signal improbable [5][7].

Traders should monitor the Met Office’s final daily summary for 13 July, which will confirm the official high once the day closes, as well as any sudden shifts in wind direction or cloud cover that could alter the final reading before 12:00 UTC [4]. With the settlement time imminent and no incoming heatwave forecast, the 5% probability aligns with the lack of a catalytic weather event; the key dependency is simply whether the current 24°C high holds or if a late-morning surge pushes the temperature into a higher bracket before the cut-off [4][6].

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.

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.

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.
