Highest temperature in Seoul (Incheon) on August 14?

Platform comparison

Market context

On 14 August 2026, the highest temperature recorded at Incheon International Airport Station will fall within one of several predefined ranges, measured in degrees Celsius. The market resolves using Weather Underground's Daily Observations table—the granular, station-level data rather than summary high-low figures—ensuring precision where discrepancies might otherwise arise. Settlement occurs at 12:00 UTC on that date, capturing the full calendar day's thermal record from South Korea's primary aviation weather station.

Seoul's August temperatures have historically clustered between 28–34°C, with extremes occasionally breaching 35°C during heat waves. The 0% crowd probability suggests traders currently perceive no meaningful likelihood of an outcome in the lowest temperature bracket offered, implying consensus around mid-to-high August heat. Comparable August readings from 2015–2023 show that days exceeding 33°C occur roughly once per fortnight during the peak summer season; this baseline helps calibrate whether 2026 conditions will track seasonal norms or deviate materially.

Traders should monitor the East Asian summer monsoon forecast and any tropical cyclone activity in the Western Pacific during late July and early August 2026, as both systems materially influence Korean peninsula temperatures. The Korea Meteorological Administration typically issues extended outlooks six to ten days before settlement; these advisories, published via their English-language portal, often signal whether high-pressure systems or moisture-laden low-pressure troughs will dominate. Regulatory accessibility varies: German GlüStV treats weather derivatives as financial instruments requiring registration above €500 notional; US CFTC exemptions apply to certain prediction markets under the Dodd-Frank framework; UK-domiciled traders under £1,500 notional exposure generally fall outside mandatory KYC thresholds on compliant platforms, though individual broker rules differ.
