Highest temperature in Seoul (Incheon) on August 13?

Platform comparison

Market context

On 13 August 2026, the highest temperature recorded at Incheon International Airport Station will determine this market's resolution. Seoul's summer climate typically peaks in early August, with daily highs routinely exceeding 30°C and occasionally reaching the mid-to-high 30s during heat waves. The resolution methodology specifies Weather Underground's Daily Observations table as the binding source, distinguishing it from summary high-low figures that may diverge due to timing or sensor variation. This precision matters: intraday temperature swings at Incheon can be material, particularly if afternoon convection or sea-breeze effects alter peak readings.

Historical August temperatures at Incheon show considerable year-to-year variance. Between 2015 and 2024, recorded highs on 13 August ranged from 26.7°C to 34.6°C, reflecting both typical summer patterns and the influence of tropical systems or blocking high-pressure systems that periodically affect the Korean peninsula. The current 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a calibration event. Given the two-year settlement window, medium-range meteorological models will become actionable only in late July 2026; early August typhoon activity or anomalous heat patterns will be the primary drivers of outcome distribution.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under Germany's GlüStV, prediction markets on weather events typically fall outside gaming restrictions if structured as information contracts. US CFTC oversight applies only if the platform operates within US reach and accepts US persons; most European-domiciled operators avoid this via geofencing. The "no-KYC up to $1,500" threshold common in some jurisdictions means retail traders can participate with minimal identity verification up to that stake level, though this market's specific platform terms govern actual limits.
