Seoul May 6 Low Temp: Will It Hit Eleven Degrees?

The Seoul temperature market for May 6 is telling a clear story right now, and the story is: 11°C is losing ground fast. Over the past 24 hours, the contract targeting an 11°C minimum has shed more than 12 percentage points in probability. That kind of move on a short-horizon weather market signals traders repricing based on updated forecast data, not noise.

The contract sits at 21% probability as of May 5, 2026. That means the market assigns a roughly one-in-five chance that Seoul’s lowest recorded temperature on May 6 lands exactly at 11°C. The other 79% is spread across competing outcomes ranging from 9°C to 17°C or higher. This is a multioutcome weather market, not a binary contract, so the real question is which temperature band the market thinks is most likely.

How the Eleven-Degree Contract Works

This contract resolves YES if Seoul’s official minimum temperature on May 6, 2026 is recorded as exactly 11°C. Resolution occurs at 2026-05-06 12:00:00 based on official meteorological data for Seoul. Any other minimum temperature means this specific contract pays out NO.

• YES (11°C minimum): Price 0.21, implied probability 21%
• NO (any other minimum temperature): Price 0.79, implied probability 79%

The NO side wins when Seoul’s minimum temperature on May 6 lands anywhere other than 11°C. Seoul’s Korea Meteorological Administration records hourly observations at multiple city stations. If the official daily minimum comes in at 10°C, 12°C, or any other value, NO collects. With eleven competing outcome bands available, the probability mass is naturally fragmented across multiple temperature targets.

Momentum and Market Signals Point Downward

The combined momentum signal here is bearish for the 11°C outcome. A 10.5% hourly drop and a 12% 24-hour decline, paired with a trend score of 64.87, suggest forecast models have shifted colder or warmer than 11°C in the most recent updates. One or two synoptic model runs can move a short-horizon temperature market sharply when resolution is less than 48 hours away.

Total volume on this contract is $5,981, with $2,999 trading in the last 24 hours. Liquidity sits at $123,508, which is deep relative to the trading volume. That liquidity figure reflects order book depth, not money wagered. With trading volume well below $1 million, this is a thin market. A single large bet could move the price significantly before resolution tomorrow.

Key Factors

• The 1-hour price change of -10.5% and the 24-hour change of -12.0% combine into a single bearish signal, most likely driven by updated numerical weather prediction output for Seoul on May 6.
• Trader sentiment is strongly bearish at 21% YES versus 79% NO, reflecting broad disagreement that 11°C is the most likely outcome band.
• Total volume of $5,981 is thin. Thin liquidity means the current 21% price can reprice sharply on any new forecast update before the 2026-05-06 12:00:00 resolution deadline.
• Seoul’s May climatology places average daily minimums in the 10°C to 14°C range, meaning several temperature bands carry plausible probability mass simultaneously.
• No whale trades are present in this market. Price movement is being driven by smaller retail-scale positions responding to forecast data.

Lines Analysis: Seoul Temperature on May Six

Here’s what the measurements are telling us. Seoul in early May sits in a transitional synoptic pattern. The Korea Meteorological Administration’s operational forecasts, combined with global ensemble guidance from models like the ECMWF and GFS, typically show meaningful spread for daily minimum temperatures at this time of year. A 2°C to 3°C spread across ensemble members is normal. That spread alone distributes probability across several outcome bands, which is exactly what this market reflects.

What makes the NO outcome real is straightforward. The Korea Meteorological Administration’s official minimum temperature observation for Seoul on May 6 landing at any value other than 11°C resolves this contract NO. Given that the market currently favors outcomes away from 11°C by a 79% to 21% margin, and given that momentum has been accelerating to the downside, the most recent forecast data appears to favor a temperature above or below the 11°C threshold. The specific competing band attracting the most probability would require checking the full outcome ladder across all eleven contracts.

Signals to Monitor

• Korea Meteorological Administration forecast updates for May 6 Seoul minimum temperature will directly reprice this contract in the final hours before resolution.
• ECMWF ensemble mean and spread for the Seoul region overnight May 5 to 6 will determine whether consensus tightens around a specific band.
• Any shift in the synoptic pattern over the Korean Peninsula, such as a cold front or blocking high, could push the minimum temperature outside the 10°C to 12°C range entirely.
• The thin volume environment means a single informed trader acting on private forecast data could move the 21% price by several points before the market closes.
• Resolution timestamp is 2026-05-06 12:00:00, so the official minimum temperature will already be recorded before resolution is confirmed.

The data doesn’t care about the politics, and in a weather market, the data is the forecast. The $5,981 in total volume tells you this is a niche contract, not a market with deep institutional conviction. The 21% price reflects genuine uncertainty about which temperature band captures the actual minimum, not confidence that 11°C is wrong. The market is pricing uncertainty, not science.

LINES VERDICT

LOW PROBABILITY, HIGH UNCERTAINTY ACROSS BANDS

The 11°C contract has lost significant ground in the last 24 hours, and momentum continues pointing downward. Updated forecast guidance for Seoul appears to be shifting probability mass toward adjacent temperature bands.

What the market says: At 21%, the market gives the 11°C outcome roughly one-in-five odds. That probability has been falling steadily and could continue moving before the 2026-05-06 12:00:00 resolution cutoff. Thin volume means the price remains volatile.

Key unknown: The Korea Meteorological Administration’s final operational forecast for Seoul’s overnight low on May 5 to 6 is the single variable that will determine where probability consolidates before this contract resolves tomorrow.

Frequently Asked Questions

• What does 21% probability mean here? The market assigns a 21% chance that Seoul’s official minimum temperature on May 6 lands exactly at 11°C. That is roughly one-in-five odds based on current forecast-driven trader positioning.
• What pays out on the NO contract? Any official Seoul minimum temperature on May 6 other than 11°C resolves this contract NO. The Korea Meteorological Administration’s recorded observation is the determining data point.
• What data event would move this price most? An updated Korea Meteorological Administration or global ensemble forecast shifting the expected overnight low away from or toward 11°C would reprice this contract immediately given its short resolution horizon.
• When does this contract resolve? Resolution is set for 2026-05-06 12:00:00. The official minimum temperature for May 6 will be available from Korea Meteorological Administration records before that timestamp.
• How reliable is the 21% price given low volume? Total volume of $5,981 is thin for a prediction market. The $123,508 in order book liquidity provides some depth, but a single significant trade could move the price sharply before resolution tomorrow.
