Highest temperature in Seoul on July 11?

Platform comparison

Market context

Seoul is expected to face peak summer heat on 11 July 2026, with the Incheon International Airport station serving as the official benchmark for the day’s highest temperature in degrees Celsius. Historical data shows July highs in Seoul typically range between 28°C and 35°C, rarely exceeding 38°C, though extreme outliers have occurred. In early July 2023, Seoul hit 37.8°C—the hottest such day in 117 years—while the national all-time record reached 41.0°C in Hongcheon in 2018[1][2]. Given that the current crowd-implied probability for any specific high-temperature range is 0% YES, the market appears to reflect either a lack of liquidity or an assumption that temperatures will fall within a default, unlisted band, rather than a genuine expectation of no heat.

Traders should monitor the Korea Meteorological Administration’s daily forecasts and real-time updates from Weather Underground, the designated resolution source, as cloud cover and monsoon activity can sharply suppress temperatures even in mid-July[2]. Recent reports note South Korea experienced its second-hottest July since 1973 in 2025, with an average of 27.1°C, suggesting a warming trend that could elevate 2026’s peak[6]. For this market to gain book depth, funding flows must align with clear on-ramp friction reductions—particularly seamless Klarna deposits and low-fee SEPA or USDC withdrawals—since payment ease directly correlates with trader participation and market liquidity on platforms like polymarket-klarna.co.uk.
