Highest temperature in Paris on August 4?

Platform comparison

Market context

Paris is set up for a fairly ordinary early-August thermal profile rather than a clear spike: the local August forecast sits around the mid-20s Celsius, with several sources putting daily highs near 25–26°C and one broader monthly view allowing highs as high as 30–32°C later in the week. That makes a final reading in the low-to-mid 20s the base case, while a hotter outcome would need a proper surge in the afternoon maximum rather than just a warm start. [2][7][16]

For framing, the current 0% implied probability looks more like a pricing quirk than a statement that the event cannot land in the relevant range. Paris’s August climate is normally warm but not extreme, with average highs clustered around 23–26°C and only limited rainfall on many days, while the warmest day of the month is typically early August. Historical August extremes show that Paris can reach much higher levels in heatwave conditions, with records around 40°C in the city, so the market still depends on whether today behaves like a standard summer day or a brief hot-weather outlier. [11][12][19]

The key catalyst is the live daytime evolution over Paris-Le Bourget, because this market settles on the highest temperature recorded there before the window closes at 12:00 UTC. Traders should watch for updated short-range forecasts and any mention of morning showers or thunderstorms giving way to sunnier conditions, since that would affect how fast temperatures can recover into the afternoon. Sortiraparis’ latest Paris and Île-de-France bulletin said Tuesday should improve after possible morning showers and thunderstorms, with highs around 30–32°C regionally, which is materially warmer than the monthly averages.

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.

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.

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.
