Highest temperature in Seoul on July 24?

Platform comparison

Market context

Seoul’s July weather is normally hot, humid and often unsettled, with average highs around 30°C and frequent rain during the monsoon season, so the daily maximum on 24 July is more likely to be driven by a short-lived break in showers than by a stable summer pattern.[1][4] A separate forecast source said Friday the 24th was expected to bring rain to the capital area, while also warning that parts of the country could still see maximum apparent temperatures above 33°C, which is the kind of split setup that can leave airport readings below inland city temperatures.[3]

The current **0% YES** price looks like a market that is either treating a specific temperature band as extremely unlikely or reflecting the fact that the event has not yet been observed; for weather markets, low probabilities often move sharply when morning clouds, rainfall timing or wind direction change. Historical July climatology for Seoul suggests a high-20s to low-30s Celsius outcome is common, but not guaranteed, and the airport-specific settlement source matters because coastal and airport stations can run cooler than central Seoul during rainy spells.[1][5] Comparable July forecasts also point to warm daytime conditions, which keeps most upside in play if precipitation is delayed.[2][6]

For accessibility, this contract’s structure sits within a wider regulatory split: in Germany, prediction markets can trigger **GlüStV** gambling-law issues if they are treated as games of chance rather than permitted financial-style products; in the United States, the **CFTC** may assert reach where a venue is offering event contracts to US persons, depending on structure and jurisdictional facts. A “**no-KYC up to $1,500**” policy means a user may be able to open and use the market with limited identity checks only until that threshold, but it does not remove any geo-restrictions, sanctions screening, or platform-level access rules that could still affect participation in this specific weather market.
