Highest temperature in Seoul on July 15?

Platform comparison

Market context

Seoul faces its peak summer heat as the city approaches the mid-July temperature peak, with the Incheon International Airport station serving as the official benchmark for this weather event. The current zero per cent crowd-implied probability suggests traders view a record-breaking high as statistically improbable for this specific date, despite the region entering its hottest seasonal window.

Historical data for Seoul in mid-July typically shows maximum temperatures ranging between 28°C and 34°C, with extreme outliers rarely exceeding 37°C at the Incheon station. Past years indicate that while heatwaves are common, the specific threshold required to trigger a "YES" resolution in this market aligns with rare, multi-day extreme events rather than standard summer variability. The absence of any current market support reflects this historical ceiling, where temperatures above 38°C remain an anomaly rather than an expectation for 15 July.

Traders should monitor the Korea Meteorological Administration’s daily heatwave advisories and real-time wunderground readings for the Incheon station, as these serve as the primary catalysts for any probability shift. A sudden surge in the 5-day forecast or an official declaration of an extreme heat emergency could act as the necessary trigger to move the market from its current stagnation. Recent climate reports from the Korean government highlight increasing summer intensity, yet no specific declaration for 15 July 2026 has been issued to justify a probability increase at this stage.
