Highest temperature in Seoul (Incheon) on August 3?

Platform comparison

Market context

The real-world event is the highest temperature recorded at Incheon International Airport Station on 3 August, measured during a day when the market settles against Wunderground’s daily history page rather than a national forecast. Current weather reporting for the Seoul capital area points to a persistent heatwave, with Seoul under a heatwave warning and daily highs around 37°C, while Incheon is forecast nearer 34°C and the broader region remains hot and humid[1][2][9].

For probability reading, the 0% YES crowd price is best treated as a thin-liquidity signal rather than a strong meteorological view, especially because the range-based settlement only depends on the day’s *observed* maximum at a single airport station. Comparable forecasts from the Korea Meteorological Administration-backed reporting and international forecasters show a wide but generally hot band for the capital area, with Seoul often a couple of degrees above Incheon on the day and tropical nights already established, which keeps upside risk alive if clear skies and inland heat advection dominate[1][2][7][10].

For traders, the main catalysts are the morning short-range forecast updates, any heatwave bulletins, and whether afternoon showers or sea-breeze effects limit the ceiling at the airport station; those operational details matter more than citywide averages because the market resolves only to the station-specific high. On accessibility and regulation, German residents face GlüStV restrictions on unauthorised gambling-style products, so practical access can be constrained regardless of price, while US persons may still face CFTC jurisdictional and platform-policy issues even if the event is weather-linked rather than financial. A “no-KYC up to $1,500” rule generally means limited participation without full identity verification up to that threshold, but it does not remove country-based blocks, sanctions screening, or exchange-specific limits for this market.
