Paris May 14 Low Temp: Will Seven Degrees Hit?

Paris weather markets resolve fast and hit hard. The question on the table is whether the lowest temperature recorded in Paris on May 14 lands exactly at 7°C. Traders are pricing that outcome at 36.5% probability, with the contract sitting at 0.37 YES after a sharp 17% jump in the last 24 hours. That move is the most interesting signal in this market right now.

The jump came as European forecast models began converging on a cooler-than-average pattern for mid-May. Paris in mid-May typically sees overnight lows between 9°C and 12°C. A reading of 7°C would sit meaningfully below that seasonal baseline. The market is pricing uncertainty, not science, and right now uncertainty is tilting toward the cooler end of the forecast envelope.

How the Paris May 14 Minimum Temperature Contract Works

This contract resolves based on the lowest temperature recorded in Paris on May 14, 2026. Resolution is set for 2026-05-14 12:00:00. The market offers a range of outcomes: 1°C or below, 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C or higher. Only the 7°C bucket pays out YES. Every other reading pays NO.

• YES (7°C resolves): priced at 0.37, implying a 36.5% probability that Paris records exactly 7°C as its daily minimum on May 14.
• NO (any other temperature resolves): priced at 0.64, implying a 63.5% probability that the minimum lands anywhere outside the 7°C bucket.

The NO contract covers a wide range. Anything above 8°C or below 6°C pays NO. That breadth is why NO holds such strong pricing. European weather forecasts for Paris on May 14 are still showing spread across the 6°C to 10°C range in ensemble models. A forecast doesn’t have to be dramatically wrong for NO to pay out. It just has to miss the 7°C target by one degree in either direction.

Momentum and Market Signals in a Thin Book

The 24-hour price change of +17.0%, a flat 1-hour reading, and a trend score of 48.04 combine into one signal: a sharp directional move that has stalled. That pattern typically means a catalyst hit, traders responded, and the market is now waiting for the next forecast update to confirm or undercut the move.

Total market volume sits at $4,904, with $4,695 of that trading in the last 24 hours. Liquidity stands at $13,494. These are thin numbers. Volume below $1 million means this price can move sharply on a single updated forecast model or a revised observation from Météo-France. A single large trade or a surprise ensemble shift could reprice the contract quickly. Treat the 36.5% figure as directionally meaningful, not as a precision probability.

• The 7°C outcome is priced at 36.5% YES after a 17% single-day move that signals fresh forecast data entered the market.
• The 1-hour flatline at +0.0% suggests the initial catalyst has been absorbed and traders are holding positions.
• Related market pricing shows the May 14 highest temperature at 40% and the May 13 lowest at 43%, framing a picture of a cooler-than-average day developing across both ends of the temperature range.
• The May 15 lowest temperature market sits at only 19%, suggesting traders expect any cool snap to be short-lived rather than a persistent pattern.
• Thin liquidity means the 36.5% price reflects a small pool of capital. It can move fast.

Lines Analysis: What the Forecast Envelope Says

The data doesn’t care about the politics. Here’s what the measurements are telling us. European ensemble models for Paris on May 14 are currently clustering overnight lows in the 6°C to 9°C range, with the modal forecast near 8°C. A 7°C reading is within the plausible range but sits roughly one degree below the most likely forecast center. That gap explains why YES is priced below 40% even after the 17% surge.

The NO side has natural width working in its favor. The minimum temperature would need to land within a single 1-degree band for YES to resolve. Météo-France ensemble spread for a 36-hour horizon typically carries plus or minus 2°C uncertainty. That spread means even a forecast centered on 7°C would produce a significant probability of landing at 6°C or 8°C instead. Both of those outcomes pay NO.

• Any Météo-France forecast update shifting the modal overnight low above 8°C would push YES probability lower and strengthen the NO side.
• A model run showing the low dropping to 6°C or below would shift probability out of the 7°C bucket entirely.
• The May 13 lowest temperature market at 43% is the most relevant comparable: if May 13 actually resolves cooler than expected, that data point could reprice May 14 quickly.
• Synoptic pattern: a clearer, calmer night on May 14 would favor radiative cooling toward 7°C or below. Cloud cover or wind would keep the low higher.

Total volume on this contract is $4,904. That thin book means the 36.5% price reflects a small group of traders responding to updated forecast data, not broad market consensus. The data is leaning toward a cool night in Paris but not decisively toward the 7°C bucket specifically.

LINES VERDICT

Forecast Uncertainty Favors NO, But the Window Is Open

The 7°C outcome is within the forecast envelope for Paris on May 14, but the natural spread of overnight low predictions makes hitting that exact bucket unlikely enough that NO holds majority pricing for good reason.

What the market says: 36.5% probability that Paris records exactly 7°C as its May 14 minimum, a sharp upward move in the last 24 hours that has now paused. With resolution at 2026-05-14 12:00:00 less than 36 hours away, this price will move fast on any updated Météo-France ensemble run.

Key unknown: The next Météo-France or ECMWF ensemble update for Paris overnight on May 13-14 is the single data point that will reprice this contract. If the model consensus shifts the overnight low center by even one degree, the 7°C bucket probability changes materially.

Scientific Context: May Temperatures in Paris

Climatological data from Météo-France shows Paris average overnight lows in mid-May near 9°C to 11°C. A reading of 7°C would represent roughly 2°C to 4°C below the seasonal norm. Such readings are uncommon but not rare in years with late-season blocking patterns or advection of continental air from the northeast. The 2026 European spring has tracked slightly cooler than the 2021-2025 average in western France, which gives the cooler forecast scenarios more credibility than they would have in a typical warm spring. The related market on the May 14 highest temperature at 40% YES also signals a cooler-than-average day is being priced across the full diurnal range, not just overnight.

Frequently Asked Questions

• What does 36.5% probability mean here? It means traders currently price a roughly one-in-three chance that Paris records exactly 7°C as its lowest temperature on May 14, based on available forecast data and market capital.
• How does the NO contract pay out? NO resolves if the Paris minimum on May 14 lands at any temperature other than 7°C. That includes 6°C, 8°C, or any other reading in the outcome list.
• What event would move this price most? A Météo-France or ECMWF ensemble update showing the overnight low shifting away from the 7°C range would reprice YES significantly in either direction.
• When does this market resolve? Resolution is set for 2026-05-14 12:00:00, using the official lowest temperature recorded in Paris on that date.
• Is this market reliable given low volume? Total volume is $4,904, which is thin. Prices can shift sharply on a single forecast update or trade. Treat the 36.5% figure as a directional read, not a precise probability.
