Highest temperature in Paris on July 23?

Platform comparison

Market context

Paris is set to stay warm rather than extreme, with the latest local forecast pointing to a partly cloudy day and no rain, and temperatures in the Île-de-France range around 15°C to 28°C. That leaves the **25°C** outcome consistent with the market’s current 100% pricing, while anything materially hotter would need a clear forecast upgrade or an unexpected late spike at Paris-Le Bourget Airport Station.[1][4]

For context, July in Paris typically produces highs in the mid-20s, with some forecast services describing recent July conditions as warmer than average but still clustering around the mid-to-high 20s rather than the low 30s.[2][3] The current 0% on **21°C or below** fits a month that is usually well above early-autumn temperatures, but it also shows how narrow the settlement range is if clouds, wind, or a weaker-than-expected warm spell cap the afternoon peak.[2][3]

The main trader watchpoints are the day’s updated official forecast, any late changes to cloud cover or wind, and the actual high recorded at Paris-Le Bourget, which is the resolution source rather than city-centre readings. With settlement tied to the day’s maximum temperature and the market open until the midday UTC cut-off, the only meaningful catalyst now is whether the observed peak lands above the currently implied 25°C band or remains within it.[1]

FAQ

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.

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.

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.

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.
