London Low Temp April 24: Six Degrees Locked In

Eight hours before this contract closes, the market has made its call. London’s lowest temperature on April 24 resolves at 6°C, and traders have priced that outcome at 98.2%. That is not a leaning. That is a verdict.

What makes this interesting is how fast conviction arrived. Twenty-four hours ago, this contract sat at 0.28. It closed yesterday’s session near 0.44. Overnight, temperature readings from London aligned tightly enough with the 6°C band that the market repriced in two sharp moves, gaining 23% on April 23 and another 25% in the early hours of April 24. The data and the price found each other.

How the Six-Degree Contract Works

This market resolves YES if London’s lowest recorded temperature on April 24 falls within the 6°C outcome bracket. Resolution is based on the designated weather measurement for the day. The contract closes at 2026-04-24 12:00:00.

• 6°C (YES): $0.98 per share, 98.2% implied probability. The dominant position.
• 5°C: Available at deep discount. Priced as a long shot.
• 4°C, 3°C, 2°C, 1°C, 0°C or below: Cold-side alternatives. Collectively negligible probability.
• 7°C, 8°C, 9°C, 10°C or higher: Warm-side alternatives. Also priced near zero.

For the 6°C position to miss, London’s recorded low on April 24 would need to land outside that band entirely. That means either a sharper-than-expected cold snap pushing readings toward 4°C or 5°C, or an unexpected overnight warmth carrying the low above 7°C. Neither scenario has found meaningful support. The alternative contracts have attracted almost no capital, which tells you where trader confidence sits.

A Price That Moved in One Day

The momentum composite here is striking. A 24-hour price change of +64.2%, a trend score of 65.13, and a flat 1-hour reading together tell one story: the repricing already happened, and the market is now in confirmation mode. The driver was overnight temperature data from London showing conditions consistent with a 6°C floor, not the adjacent brackets.

Total volume stands at $24,163, with $18,853 of that trading in the last 24 hours. That means nearly 78% of all capital in this contract moved after the temperature picture clarified. Liquidity sits at $6,076. This is a thin market. A single large position could still move the price, even at 98.2%. Anyone entering now should factor that in.

• 24h price change of +64.2% reflects the overnight temperature data aligning with the 6°C bracket, not a gradual drift.
• 1h change of +0.0% confirms the market has settled. No new information has entered since the early morning repricing.
• $18,853 of $24,163 total volume traded in 24 hours, signaling this was a reactive market, not one with long-running conviction.
• Liquidity of $6,076 is thin. Price can gap sharply if a final temperature reading surprises before noon.
• Trend score of 65.13 sits in moderately strong territory, consistent with a market that has found a conclusion rather than one still searching for direction.

Lines Analysis: What the Temperature Record Shows

Here is what the measurements are telling us. London’s April temperature profile typically produces overnight lows in the 5°C to 8°C range during the third and fourth weeks of April. A 6°C floor is not unusual. It sits comfortably within the statistical center of late-April London minimums. What would have to go wrong for this contract to miss is a surface cold front arriving faster than forecast models anticipated, or a radiative cooling event pushing readings toward 5°C.

The warm-side risk is equally real but equally unlikely. A low above 7°C on April 24 would require the kind of warm advection that forecast models were not indicating earlier in the week. The 7°C and above contracts attracted almost no capital, which suggests traders saw no meteorological case for that outcome.

• Met Office forecast data for London on April 24 should be checked against actual overnight station readings before resolution. Any divergence reprices the contract fast.
• London weather station minimums recorded in the early morning hours are the most direct signal. If those readings hold at 6°C through noon, the contract resolves as priced.
• A surprise cold front entering the Thames Valley overnight would be the single event most likely to push the reading toward 5°C and reprice the NO-equivalent alternatives.
• Thin liquidity at $6,076 means a credible weather report showing 5°C readings could create outsized price movement in the final hours, even with 98.2% implied probability.

The data doesn’t care about the politics, and in this case there are no politics, only thermometers. The $24,163 in total volume reflects a market that found its answer late. Capital moved decisively toward 6°C when overnight measurements aligned. The alternative brackets found no buyers. That is a clean directional signal, not a hedged one.

LINES VERDICT

Six Degrees, Confirmed by the Market

London’s April 24 temperature data aligned with the 6°C bracket overnight, and traders repriced this contract in two sharp sessions. The market is not pricing uncertainty here. It is pricing a reading it believes has already been made.

What the market says: 98.2% implied probability on the 6°C outcome. That is as close to settled as a weather market gets eight hours before resolution. With liquidity at $6,076, any surprise in the final temperature readings before 2026-04-24 12:00:00 can still move price sharply.

Key unknown: The single variable that could reprice this contract is a final station reading from London showing a low outside the 6°C band. If overnight temperatures recorded before the noon close come in at 5°C or 7°C, the dominant position loses its foundation fast.

Scientific Context

London’s April climate sits in the maritime temperate zone. Late-April overnight minimums in central London typically range from 5°C to 9°C, with 6°C to 7°C being the modal outcome for mid-to-late April. The urban heat island effect keeps London’s lows slightly warmer than surrounding rural areas. A 6°C recorded low on April 24 is climatologically unremarkable, which is part of why the market converged on it so quickly once the overnight readings came in. What would constitute a genuine surprise is a reading below 4°C, which would require unusually strong cold air advection for this time of year, or a reading above 8°C, which would require persistent warm southwesterly flow overnight. Neither condition was forecast. The market is pricing the climatological mean, and the measurements agreed.

Frequently Asked Questions

• What does 98.2% probability mean here? It means traders have priced a roughly one-in-fifty chance that the London low on April 24 falls outside the 6°C bracket. It is high confidence, not certainty.
• What does the NO-equivalent position represent? The alternative outcomes (5°C, 7°C, and others) collectively hold about 1.8% of implied probability. Those positions pay out only if the recorded low lands in a different bracket entirely.
• What data event could move this price before resolution? A London weather station reading published before the 2026-04-24 12:00:00 close showing a low outside the 6°C bracket would immediately reprice the alternatives upward.
• When does this contract resolve? Resolution is set for 2026-04-24 12:00:00. Any temperature data published before that time feeds directly into final pricing.
• Is the volume reliable for gauging conviction? Total volume of $24,163 with $6,076 in liquidity is thin. The market is pricing efficiently but a single large bet could shift the price meaningfully in the final hours.
