Highest temperature in Paris on August 5?

Platform comparison

Market context

Paris’s daytime high is being set by a warm August setup rather than anything volatile in the wider calendar, with forecast services clustering around the mid-to-high 20s Celsius for 5 August and some showing roughly 29°C for the day in the city. The market resolves on the *highest* temperature at Paris-Le Bourget Airport, which matters because airport readings can run a little differently from central Paris, especially under clear skies and light winds. The current 0% yes price looks very low against those forecasts, but it may simply reflect thin early liquidity rather than a strong view on the weather itself.[1][11][13]

The historical frame is straightforward: Paris in August is usually comfortable, with long-run daytime highs around the low-to-mid 20s Celsius, yet recent European summers have shown that short-lived heat spikes can lift French temperatures well above seasonal norms.[7][10][15] France’s June 2026 heatwave produced extreme readings nationwide and Paris itself reached 40.9°C, underlining that a single hot ridge can overwhelm the monthly average.[3][12][15] For a one-day market like this, traders should focus on whether the synoptic pattern stays benign or shifts into another heat dome, because even a modest forecast revision of a few degrees can move the relevant range.

The main catalysts are the next short-range forecast updates, cloud cover and wind expectations for the airport specifically, and any official Météo-France escalation if heat-risk language appears. Paris weather outlets currently lean dry and sunny for the day, which supports a middling high rather than an extreme, while broader services still show a small tail risk into the low 30s Celsius if heating is stronger than expected.[13][11][2] The settlement source is Wunderground’s Paris-Le Bourget history page, so the key dependency is the station’s recorded daily maximum rather than a citywide estimate.[0]

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.

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.
