This market asks whether Seoul's daily high temperature will be exactly 12°C on May 2, 2026. The 0% odds indicate traders believe this outcome is extremely unlikely. Early May in Seoul typically sees highs between 18-23°C as the region transitions from spring to early summer. A high of just 12°C would represent unseasonably cool weather, roughly 8-10 degrees below normal for this date. The market reflects trader conviction that Seoul's weather patterns will follow historical norms rather than produce an unusually cold day. Understanding what drives this prediction requires looking at recent Seoul temperature trends, seasonal patterns, and any weather systems that could unexpectedly cool the region. The specificity of the 12°C target makes resolution straightforward — Seoul's meteorological authority reports daily highs with precision, allowing definitive determination on May 2 at midnight UTC. Traders pricing this at 0% are essentially betting that spring's warming trajectory will continue uninterrupted.
Deep dive — what moves this market
Seoul's climate in early May reflects the region's transition from spring to early summer, with historical records showing daily highs typically ranging from 18 to 23 degrees Celsius. The 12°C threshold represents a significant departure from climatological norms — roughly 8 to 10 degrees cooler than the average May 2 high. Understanding what would be required for such unusually cool weather involves examining both historical patterns and meteorological systems that could influence early May conditions. A strong cold front from northern China or Mongolia could push unusually cold air into the Korean peninsula, suppressing temperatures well below seasonal norms. This occurs occasionally in early May, though infrequently — perhaps 5-10% of years see anomalously cold May days in Seoul. Persistent cloud cover combined with cool maritime influences from the Yellow Sea could also contribute to dampened temperatures. However, factors supporting typical warm conditions align more closely with historical expectations. Seoul typically experiences warming and lengthening daylight in early May, with increasingly frequent warm, sunny days as the region transitions into early summer. High-pressure systems from the Pacific and warming continental air masses dominate May weather patterns most years. Spring precipitation and cloud cover tend to decrease by early May, allowing solar radiation to warm daytime temperatures substantially. Historical data shows that cold May days in Seoul, defined as highs below 15°C, occur only 10-15% of the time on average. The 0% odds suggest traders believe the probability approaches zero that Seoul's high will be exactly 12°C — not just below that threshold but specifically that single measurement. Weather systems produce temperature ranges, not single-degree outcomes. Achieving exactly 12°C as a daily high requires both unusual meteorological conditions and specific timing. Recent years show Seoul's May 2 temperatures have ranged from roughly 14-25°C, with 12°C appearing in historical records perhaps once per decade or less. The market's pricing reflects this statistical rarity combined with seasonal momentum favoring warmth.
What traders watch for
Korea Meteorological Administration releases official May 2 high temperature at 23:59 UTC. Whole-degree precision determines resolution.
Weather forecast models released May 1 evening will indicate whether any cold front or system could suppress Seoul's peak temperature toward 12°C.
Seoul's historical May 2 highs average 18-22°C; temperatures below 15°C occur only 10-15% of years, supporting low probability.
Cloud cover and atmospheric moisture on May 2 will influence solar radiation balance; clear skies typically raise highs 5-8°C higher.
How does this market resolve?
The market resolves YES on May 2, 2026 at 23:59 UTC if Seoul's reported daily high temperature equals exactly 12°C according to the Korea Meteorological Administration. Any other recorded high resolves NO.
Prediction markets aggregate trader expectations into real-time probability estimates. On Polymarket Trade, every market question resolves YES or NO based on a specific event outcome; traders buy shares of the side they believe will resolve positively.
