Highest temperature in Paris on August 1?

Platform comparison

Market context

Paris on 1 August will be judged by the day’s maximum temperature at Paris–Le Bourget Airport, so the market is really about whether the city’s early-August warmth reaches the upper 20s or pushes into the low 30s. The crowd is pricing a **29°C** outcome at **70%**, with **28°C** next at **18%**, which implies expectations for a warm but not extreme day rather than a sustained heatwave spike.[2]

That pricing sits close to the seasonal norm. AccuWeather’s August outlook for Paris shows average highs around **26°C**, while historical August data also centres on the mid-20s, so a reading around 28–29°C would be a modestly warm day rather than a statistical outlier.[1][4] The comparison case that matters is recent French heat, not deep-summer averages: Reuters and other outlets reported France’s June 2026 heatwave pushing Paris to **40.9°C** and triggering broad warnings, but that was an exceptional synoptic set-up, not the baseline for early August.[12][14][16]

For traders, the key catalyst is the evolving late-July to early-August pattern over northern France. The current Polymarket note cites numerical weather models from **Météo-France** and **ECMWF** pointing to a daytime maximum near **28.5°C** under persistent high pressure, which would leave the market concentrated around **28–29°C** unless the ridge strengthens further or cloud/sea-breeze influence trims the peak.[2] The practical watchpoints are any updated model runs, Météo-France advisories, and whether the station’s published daily high is revised before the first datapoint of 2 August, since that is the settlement cut-off.[2]

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.
