Paris May 2 Low Temp: Will Thirteen Degrees Hit?

A single temperature reading will settle this contract. Paris traders have converged hard on 13°C as the lowest temperature recorded in the French capital on May 2, 2026. At 75.5% implied probability, the market is treating this outcome as the clear favorite, but with resolution just hours away and thin total volume, one sharp data shift could reprice everything quickly.

Here’s what the measurements are telling us: early May in Paris typically sees overnight lows between 10°C and 14°C, with the long-run average for this date sitting close to 11°C to 12°C. Current synoptic patterns over northwest Europe are showing a mild airmass, which supports the higher end of that range. The 13°C outcome sits squarely in the zone where model guidance and recent temperature trends converge.

How the Paris May 2 Temperature Contract Works

This contract resolves YES if the lowest recorded temperature in Paris on May 2, 2026 equals exactly 13°C. Resolution occurs at 2026-05-02 12:00:00, based on official meteorological observation. The market offers a full range of outcomes from 9°C or below through 19°C or higher, making this a multi-outcome market where exactly one bucket wins.

• 13°C (YES): Current price 0.76, implied probability 75.5%
• 14°C: Alternative outcome, lower implied probability
• 12°C: Alternative outcome, lower implied probability
• 15°C: Alternative outcome, lower implied probability
• 11°C and below buckets: Require a significant cold intrusion
• 16°C and above buckets: Require an unusually warm overnight minimum

The NO scenario here means any outcome other than exactly 13°C resolves this specific contract worthless. Météo-France operational observations and synoptic model output both currently point away from the colder buckets (12°C and below). The warmer buckets (14°C and above) remain the more credible alternative if the mild airmass over France pushes overnight minimums higher than current guidance suggests. A cloud cover increase overnight on May 1 into May 2 would trap warmth and nudge the low toward 14°C or 15°C, which is the primary risk to this contract.

Momentum and Market Signals Show Sharp Conviction Shift

The momentum composite here is striking. A combined signal of plus 41% over one hour, plus 27% over 24 hours, and a trend score of 85.27 all point to one driver: updated numerical weather prediction output released in the past 24 hours shifted model consensus toward the 13°C bucket. That kind of intraday repricing in a short-fuse weather market typically follows a model run, not a change in trader sentiment.

Total market volume sits at $3,753, with $2,636 of that moving in the last 24 hours. Liquidity depth registers at $86,341, which is deep relative to volume. That liquidity gap matters: the order book can absorb trades without large price swings, but the thin total volume means this market has not seen heavy two-sided action. Any informed trade of meaningful size arriving before resolution could still move the contract price noticeably.

• The 1h and 24h momentum combine to show the strongest single-day repricing since this contract opened, driven almost certainly by model consensus tightening around 13°C.
• Liquidity at $86,341 is unusually deep for a $3,753 volume market, suggesting passive market makers are holding positions rather than active two-sided trading.
• The 75.5% YES price reflects model-aligned confidence, not just trader sentiment.
• With resolution at 2026-05-02 12:00:00, less than 19 hours remain for new data to arrive and reprice the contract.
• The 24.5% NO-side capital is spread across at least ten alternative temperature buckets, diluting any single opposing signal.

Lines Analysis: What the Temperature Data Supports

European Centre for Medium-Range Weather Forecasts and Météo-France operational guidance for Paris on the night of May 1 into May 2 both support a mild overnight minimum. The current surface pressure pattern over France shows southwesterly flow, which historically correlates with overnight lows in the 12°C to 14°C band for early May. The 13°C bucket sits at the center of that distribution. That is why traders moved hard to this outcome on updated guidance.

The realistic path to any outcome other than 13°C runs through cloud cover. A clearer sky overnight would allow radiative cooling, pushing the minimum toward 11°C or 12°C. A thicker low cloud deck would suppress cooling and push the low toward 14°C or 15°C. Current guidance shows partial cloud cover, which is precisely the condition that produces 13°C minimums. That ambiguity is the only thing keeping the 24.5% NO-side capital in play.

• Météo-France nowcast updates through the evening of May 1 will be the most important signal before resolution.
• Any shift in the European Center ensemble toward 14°C or higher would be the clearest catalyst to reprice this contract downward.
• Urban heat island effects in Paris consistently push overnight minimums 1°C to 2°C above rural surrounding areas, supporting the higher end of the plausible range.
• Synoptic model consensus narrowing further toward 13°C in the next operational run would likely push the contract price above 80%.
• A late-evening precipitation event, which would modify surface temperatures, remains a low-probability wildcard.

With $3,753 in total volume and resolution at 2026-05-02 12:00:00, the data clearly favors the 13°C outcome. The market is pricing uncertainty, not science, and right now the uncertainty is narrowing. The primary question before resolution is whether the final Météo-France observation confirms what the models are currently showing.

LINES VERDICT

Thirteen Degrees as the Favored Outcome

Current model consensus and synoptic pattern analysis both align with the 13°C bucket. The market repriced sharply on updated guidance, and the data does not care about the politics of whether this was a surprise move.

What the market says: 75.5% probability for 13°C as Paris’s overnight low on May 2, a price that jumped hard on fresh model output. With resolution in less than 19 hours, the contract is near its final configuration unless a late observation surprises.

Key unknown: The final Météo-France operational observation for the overnight period on May 1 into May 2 is the single data point that determines resolution. Any divergence between model guidance and actual measurement would immediately reprice the contract toward an alternative outcome.

Scientific Context: Early May Temperature Patterns in Paris

Paris overnight lows in early May average near 11°C to 12°C based on Météo-France historical records. The 13°C outcome is approximately one degree above that historical average, consistent with the mild airmass pattern currently over France. Urban heat island effects in central Paris are well-documented and add roughly 1°C to 2°C compared to Orly Airport observations, which matters for which official station governs resolution. The market price moved from 0.32 at open to 0.76 today, a shift fully explained by the convergence of operational model guidance around the 13°C threshold over the last 48 hours. Before resolution at 2026-05-02 12:00:00, the only events that would move this contract are a revised ensemble model run showing a temperature shift, a late-breaking precipitation or wind event over Paris, or a change in the observing station used for resolution.

Frequently Asked Questions

• What does 75.5% probability mean here? Traders are collectively placing roughly a three-in-four chance that the official lowest recorded temperature in Paris on May 2 equals exactly 13°C. Probability reflects collective market belief, not a meteorological guarantee.
• What happens to NO capital? Capital placed against the 13°C outcome is spread across ten or more alternative temperature buckets. Each alternative bucket is independently priced, and only the bucket matching the actual observation pays out.
• What single event would most move this price? A Météo-France operational forecast update or ensemble model run shifting consensus to 14°C or 12°C would immediately reprice the 13°C contract lower and alternative buckets higher.
• When does this contract resolve? Resolution occurs at 2026-05-02 12:00:00, based on the official temperature observation recorded in Paris on May 2, 2026.
• Is the volume reliable enough to trust this price? Total volume is $3,753, which is thin. Liquidity at $86,341 is deep, but low volume means prices can shift sharply on a single informed trade or data update before resolution.
