Chongqing April 27 High Temp: Will It Hit Twenty-One?

Chongqing’s weather markets rarely move this fast. The contract on the city’s April 27 daily high has jumped 41 percent in 24 hours, landing at a 66.5 percent implied probability that the peak temperature lands exactly at 21 degrees Celsius. That is a sharp directional signal for a market resolving in less than a day. The momentum composite, combining the 24-hour surge, a 23.5 percent one-hour jump, and a trend score of 86.87, points to traders converging on one outcome with unusual conviction.

This is a hyperlocal weather market, but the mechanics are straightforward. Chongqing sits in the Sichuan Basin, where April temperatures are modulated by southwesterly moisture flows and occasional cold air intrusions from the north. Late April typically produces highs in the 19-to-24 degree range. The market is not pricing climate science. The market is pricing a 24-hour forecast window, and right now traders are clustering around 21 degrees Celsius with real money.

How the Twenty-One Degree Contract Works

This contract resolves on whether Chongqing’s highest recorded temperature on April 27 falls at exactly 21 degrees Celsius. Resolution is set for 2026-04-27 12:00:00. The outcome field that pays is a single-degree bin, which means adjacent outcomes at 20 degrees or 22 degrees are separate contracts. Traders here are not betting on a range. They are betting on a specific one-degree outcome.

• YES (21 degrees Celsius): Priced at 0.67, implying a 66.5 percent probability. Pays if the official high reading lands at exactly 21 degrees Celsius.
• NO (any other temperature): Priced at 0.34, implying a 33.5 percent probability. Pays if the high lands at 20 degrees, 22 degrees, or any other bin.

The alternative outcomes span a wide range: 15 degrees or below, 16, 17, 18, 19, 20, 22, 23, 24, and 25 or higher. Each is a separate contract. The 21-degree bin commanding 66.5 percent probability suggests the broader market has already resolved the temperature range question. The debate is whether the reading lands at 21 exactly or slips one degree in either direction.

What the Price Movement Is Telling Traders

The momentum composite here is not subtle. A 41 percent 24-hour gain, a 23.5 percent one-hour jump, and a trend score of 86.87 together suggest a weather model update or a new forecast release drove traders to reprice sharply. Chongqing’s National Meteorological Station typically updates its short-range forecasts in the early morning and afternoon. A forecast revision pegging the April 27 high at 21 degrees Celsius would explain exactly this kind of concentrated, fast-moving price action.

Total volume on this contract is $28,068, with $21,456 of that trading in the last 24 hours. That means roughly 76 percent of all activity happened in a single day. Liquidity sits at $3,084, which is thin. Thin liquidity means a single large trade can move the price significantly. The fast price action seen in the last 24 hours is partly a function of that shallow order book, not just trader conviction. New forecast data arriving before resolution could move this contract sharply in either direction.

• One-hour change of +23.5 percent and 24-hour change of +41.0 percent together signal a single catalyst, most likely a forecast update, drove the repricing rather than gradual opinion drift.
• Total volume of $28,068 with $21,456 in the last 24 hours confirms this is a late-stage, momentum-driven market, not a steady-state pricing environment.
• Liquidity of $3,084 means the market is vulnerable to sharp swings if any trader moves a meaningful position before the 2026-04-27 12:00:00 close.
• Trend score of 86.87 is one of the stronger directional readings in a short-window weather market. It reflects speed of movement, not duration of consensus.

Lines Analysis: Reading the Chongqing Forecast Window

The case for the 21-degree outcome rests on Chongqing’s late April climatology and what appears to be a converging numerical weather prediction. Late April in the basin typically produces highs between 19 and 23 degrees Celsius. The 21-degree bin sits in the center of that distribution. When forecast models align on a specific degree value in the 24-to-48-hour window, prediction markets for single-degree bins often see exactly this kind of rapid price compression. The market is telling you the models agree.

The risk for the 21-degree contract is real and specific. Single-degree bins lose when the actual high comes in one degree above or below the target. A 22-degree reading, driven by stronger afternoon sunshine or a shift in wind direction, moves the contract to zero. A 20-degree reading, driven by cloudier skies or earlier cold air, does the same. The NO contract at 0.34 is not priced at noise levels. It reflects genuine uncertainty about the final decimal-point precision of a 24-hour forecast.

• Any update from Chongqing’s National Meteorological Station revising the April 27 forecast up to 22 degrees would collapse the YES contract immediately.
• A downward revision toward 20 degrees, triggered by an approaching cloud system or cold advection from the north, carries similar repricing risk.
• Thin liquidity of $3,084 means the closing price could diverge significantly from the true probability if a single trader exits or enters a large position.
• The resolution timestamp of 2026-04-27 12:00:00 creates a hard stop. No late data adjustments affect the outcome after that point.
• Regional weather patterns for late April in Sichuan Basin historically show high day-to-day variability near the 20-to-22 degree range, which is precisely where this contract sits.

At $28,068 total volume and 66.5 percent implied probability, the market is leaning clearly toward 21 degrees Celsius. The data, as it stands, favors the YES side. But the 33.5 percent NO price is honest about one-degree bin risk. This contract resolves on precision, not direction. Here is what the measurements are telling us: the forecast window is narrow, the liquidity is thin, and the next meteorological update before 2026-04-27 12:00:00 is the only thing that matters now.

LINES VERDICT

Twenty-One Degrees Is the Market’s Best Estimate, but Precision Risk Remains Real

The momentum, volume concentration, and probability level all point to traders pricing a converging forecast. The thin liquidity means the number should be held loosely until resolution.

What the market says: At 66.5 percent, the 21-degree Celsius outcome is the clear favorite, but the 33.5 percent NO price reflects genuine single-degree bin uncertainty ahead of the 2026-04-27 12:00:00 close. With only $3,084 in liquidity, any late forecast revision could reprice this contract sharply in the final hours.

Key unknown: The next Chongqing National Meteorological Station forecast update before resolution is the single data point that could shift this contract. A one-degree revision in either direction moves the probability dramatically given how thin the order book is.

Scientific Context

Chongqing’s position in the Sichuan Basin creates a microclimate that amplifies temperature variability in spring. The basin’s topography traps warm air during anticyclonic conditions and accelerates cooling when cold fronts penetrate from the northwest. April daily highs in Chongqing span a historically wide range, from below 15 degrees to above 25 degrees, depending on synoptic conditions. The 21-degree target sits at the climatological mode for late April, which is why the market has gravitated toward it. But the standard deviation of daily highs in this period is large enough that adjacent bins remain live options. Before the 2026-04-27 12:00:00 resolution, any significant change in the synoptic pattern, particularly a faster-than-expected cold front or a stalling high-pressure system, would be the event that reprices this contract away from its current 66.5 percent level.

Frequently Asked Questions

• What does 66.5 percent probability mean here? The market is saying that, given current forecast information, there is roughly a two-in-three chance the April 27 high in Chongqing lands at exactly 21 degrees Celsius. It is not a guarantee. It is a collective estimate based on trader bets.
• What does the NO contract cover? The NO contract at 0.34 pays out if the Chongqing daily high on April 27 lands at any temperature other than 21 degrees Celsius, including 20 degrees, 22 degrees, or any other listed bin.
• What event would move this price most before resolution? A Chongqing National Meteorological Station forecast update shifting the expected high by even one degree would reprice this contract sharply, given the thin liquidity of $3,084 in the order book.
• When does this market resolve? The contract resolves at 2026-04-27 12:00:00. No post-resolution adjustments apply. The official high temperature reading at that point determines the outcome.
• Is $28,068 in volume enough to trust the price? It is a low-volume market. With only $3,084 in liquidity, the 66.5 percent probability can shift significantly on a single trade or a new forecast release. Treat the price as directional, not precise.
