Highest temperature in Paris on August 18?

Platform comparison

Market context

On 18 August 2026, the highest temperature recorded at Paris-Le Bourget Airport will fall into one of several defined ranges. The market resolves using the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when stations report multiple readings throughout a day. Le Bourget, situated north of central Paris, typically experiences summer highs between 24–28°C, though heat waves can push readings substantially higher.

Historical August temperatures in the Paris region show considerable year-to-year variation. The summer of 2022 saw extreme heat across Europe, with Paris recording 40°C on multiple days; conversely, cooler Augusts have produced highs around 20°C. The 0% crowd probability suggests traders are either confident in a specific temperature band or uncertain about which range will resolve. Recent precedent from comparable weather markets indicates that crowd estimates tend to cluster around seasonal norms unless significant weather alerts precede the settlement date. Meteorological forecasts become reliable only 10–14 days before the event, meaning early traders are pricing largely on climatological averages rather than actual synoptic conditions.

Traders should monitor European weather models and heat-wave alerts from Météo-France as August approaches. Any Atlantic low-pressure systems or high-pressure domes forming over continental Europe in mid-August will shift probabilities materially. The settlement window closes at midday on 18 August, so readings must be finalised before afternoon peak temperatures occur—a timing constraint that occasionally creates discrepancies between daily highs and intraday observations.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
