Highest temperature in Paris on July 5?

Platform comparison

Market context

The underlying event is the daily maximum temperature recorded at Paris-Le Bourget Airport on 5 July 2026, with the market currently pricing a 0% chance that this peak hits exactly 30°C. Historical data for early July in Paris shows average highs near 25°C, yet the 2026 European heatwaves have pushed temperatures well above seasonal norms, with recent days in July 3–4 reaching 36–37°C across northern France[4]. While the market treats 30°C as the single most likely discrete outcome in other venues (implied at 44.5% elsewhere), the current 0% probability here suggests a sharp divergence, possibly reflecting a belief that the peak will land in adjacent buckets like 29°C or 31°C rather than hitting the exact 30°C mark[1].

Traders must watch the next Météo-France or ECMWF medium-range forecast update, as the contract resolves in under 48 hours and is highly sensitive to these revisions[1]. The prevailing heatwave building across France has issued red alerts for 54 departments, indicating persistent high temperatures around the clock, which increases the likelihood of peaks exceeding 30°C but not necessarily landing exactly on it[6]. Recent news confirms dry conditions with almost no rain expected and intense sunshine driving UV levels higher, limiting overnight cooling and sustaining warm nights near 21–23°C[4]. Any sudden shift in cloud cover or precipitation forecasts before the 12:00 UTC settlement window could instantly alter the probability mass across the ten alternative temperature buckets that count as NO.

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.
