Highest temperature in Paris on August 3?

Platform comparison

Market context

Paris on 3 August is being priced as a fairly ordinary summer heat outcome rather than a breakneck extreme, with the market leaning to a maximum around **35–36°C** and only a **1%** chance on the highest bracket. That sits in line with the current crowd split on Polymarket, where 35°C is the front-runner at 38% and 36°C is next at 29%, while the tails above 37°C are thin[2]. For a Paris station-based settlement, the key question is not whether the city is warm, but whether it pushes far enough to challenge the upper bins before the daily high is locked in[2].

Recent heat has given traders a useful frame of reference. Paris reached **40.9°C** during the late-June 2026 heatwave, one of the most intense spells in recent memory, but official reporting also showed temperatures across France easing from the sharpest peaks as the event matured[6][7][12]. That matters because August highs in Paris can still be elevated without repeating the June extremes; the current pricing implies the market expects hot but not exceptional conditions, with a bias towards the mid-30s rather than a run at 38°C-plus[2].

The main catalysts are the next runs of mesoscale guidance and any updated local forecasts from Météo-France and ECMWF ensembles, which have already been described as fairly tight for this lead time[2]. Traders should also watch for whether the warm air mass over western Europe persists into the day itself, since small shifts in cloud, wind and timing of afternoon heating can move the station maximum by a degree or two and decide whether the result lands in 34–35°C or 36–37°C bands[2][7].

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.

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.

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.
