Paris June 7 Low Temp: Will 12°C Hit?

A single-day temperature market for Paris is about as narrow as prediction markets get. The contract asks one question: does the lowest recorded temperature in Paris on June 7, 2026 land exactly at 12°C? Traders are pricing that outcome at 33%. With eleven possible buckets spanning 7°C or below all the way to 17°C or higher, that’s actually a meaningful concentration of probability on one value.

The market question is: what is the lowest temperature in Paris on June 7? The 12°C outcome trades at $0.33 YES and $0.67 NO. The market closes June 7, 2026 at 12:00 UTC. Total volume stands at $1,546, with all of that arriving in the last 24 hours.

How the 12°C Contract Works

A YES resolution requires the official lowest temperature recorded in Paris on June 7 to fall precisely at 12°C, not 11°C, not 13°C. The resolution source is the market’s designated weather data feed for Paris. Ten other temperature buckets each carry their own separate contracts.

• YES ($0.33, 33% implied): Paris records a June 7 overnight low of exactly 12°C.
• NO ($0.67, 67% implied): Paris records any other temperature, from 7°C or below to 17°C or higher.

The NO side collects if the overnight low lands on any of the ten competing buckets. June in Paris typically sees overnight lows ranging from 9°C to 16°C, so multiple outcomes hold real probability. That spread across eleven buckets explains why even the leading outcome carries only a 33% price.

Momentum and Market Signals

The momentum composite here is thin but directional. The trend score sits at 47.52, the 1-hour change is flat at 0.0%, and the 24-hour price history showed a sharp move up 14.5% earlier on June 6 before pulling back 7.5% later the same day. That pattern suggests a weather forecast update repriced the contract mid-day, then partial reversal as forecast uncertainty reasserted itself. The net effect: 12°C moved from a $0.26 open to the current $0.33.

Total volume is $1,546, and all of it came in the last 24 hours. This is a brand-new, highly illiquid market. Liquidity stands at $14,790 against near-zero open interest. At this volume level, a single large bet moves the price sharply. The $14,790 in the order book is the real story: market makers have posted depth, but trader conviction is thin.

• The 12°C bucket moved from $0.26 to $0.33 on June 6, a 27% price increase driven by what appears to be a forecast revision toward warmer overnight lows.
• The 1-hour change of 0.0% suggests the market has stabilized temporarily ahead of the June 7 resolution.
• Volume below $1,000 per bucket is common in single-day weather markets. Price can move 10+ points on a single trade.
• Liquidity at $14,790 is the deepest signal here. Market makers are willing to provide two-sided quotes, but active trading is minimal.
• Trader sentiment reads strongly bearish: 33% YES, 67% NO, consistent with the multi-outcome structure.

Lines Analysis: Paris June 7 Temperature

Here’s what the measurements are telling us. European numerical weather prediction models, including ECMWF and the French national model run by Météo-France, typically lock in overnight low forecasts within one to two degrees of actual outcomes at 24-hour lead time. As of June 6, the forecast for Paris overnight lows on June 7 appears centered near 12°C to 13°C, which explains why the 12°C bucket has attracted the most probability. The data doesn’t care about the politics of which bucket wins. It cares about the 850 hPa temperature advection and surface radiative cooling overnight.

The competing buckets are the real risk. The 11°C and 13°C outcomes each likely carry 20% or more of market probability on their own contracts. A one-degree forecast error, which is well within normal model spread for a June night in Paris, shifts the winning bucket entirely. The 12°C contract is the market’s best single guess, but a 33% price on eleven outcomes means the market is explicitly acknowledging it probably won’t be 12°C. The market is pricing uncertainty, not science.

• Météo-France 24-hour forecast verification: if the June 7 low shifts to 11°C or 13°C in updated model runs, the 12°C contract reprices sharply lower.
• Overnight cloud cover: clear skies over Paris would enhance radiative cooling and push the low toward 11°C or below. Cloud cover holds temperatures higher, favoring 13°C or above.
• Wind direction: a southerly flow on June 7 brings warmer air off the continent. A northerly component would cool the surface boundary layer faster.
• Final Météo-France or ECMWF ensemble forecast issued June 6 evening: the strongest single signal for this contract before resolution.
• Resolution timing: the market closes at 12:00 UTC on June 7, before daytime warming obscures the overnight minimum reading.

Total volume at $1,546 is too thin to treat as strong collective wisdom. The 33% price on 12°C reflects the logical concentration of probability around the most-forecast value, but a meteorological model update in the next 12 hours could move this contract 10 to 15 points in either direction. The data tilts toward 12°C as the single most likely outcome. It does not tilt toward 12°C as a probable outcome. Those are different claims.

LINES VERDICT

LEADING BUCKET, THIN CONVICTION

The 12°C bucket holds the highest single-outcome probability in a fragmented eleven-way market, but a 33% price means the market is mostly pricing the adjacent buckets as equally plausible. The overnight forecast, not current trader positioning, is the decisive input.

What the market says: 33% implied probability means traders believe 12°C is the single most likely Paris low on June 7, but the eleven-bucket structure means NO (any other outcome) holds a commanding 67%. With a resolution date of June 7 at 12:00 UTC, volatility will concentrate in the final 12 hours as overnight temperature readings come in.

Key unknown: The final Météo-France ensemble forecast issued June 6 evening is the single most important data point. A one-degree shift in the modeled overnight low would reprice this contract and the adjacent 11°C and 13°C buckets simultaneously.

Scientific Context

Paris June overnight lows have historically ranged from 8°C to 16°C across the first ten days of the month, based on Météo-France climatological records. The long-run June 7 average low sits near 12°C to 13°C, which is consistent with the current market pricing. Urban heat island effects in central Paris tend to keep overnight lows 1°C to 2°C above suburban and airport reference stations. Resolution depends on which station the market designates. That station choice is the quiet technical variable that rarely gets discussed in weather prediction markets.

Before June 7 resolution, two events could move the 12°C contract price materially: a Météo-France forecast update showing the low trending toward 13°C or above, or a clear-sky radiative cooling signal overnight that pushes the low toward 11°C. Either would shift volume to adjacent buckets and pull price away from 12°C.

What is the 33% probability actually telling me?

It means traders assign a one-in-three chance the Paris overnight low lands exactly at 12°C on June 7. Ten other temperature buckets share the remaining 67% of probability.

What pays out on the NO side?

Any Paris overnight low other than exactly 12°C resolves NO. That includes 11°C, 13°C, and all other listed buckets.

What data event would move this price most?

A Météo-France or ECMWF forecast update on June 6 evening showing the overnight low trending away from 12°C would reprice this contract and adjacent buckets sharply.

When does this market resolve?

The market closes June 7, 2026 at 12:00 UTC, capturing the overnight minimum temperature before daytime heating begins.

Is the $1,546 volume enough to trust the price?

Volume this thin means price can move 10 or more points on a single trade. The $14,790 in liquidity provides order book depth, but the price signal here reflects forecasts more than collective trader wisdom.
