Highest temperature in Seoul on July 31?

Platform comparison

Market context

The key real-world event is the **highest temperature recorded at Incheon Intl Airport Station on 31 July 2026**, with settlement tied to the daily maximum on that date rather than to general Seoul weather. July in Seoul typically sits in the mid-20s Celsius on average, but forecasts for late July have shown highs in the low-to-mid 30s Celsius, which keeps the upper temperature bands live even when the market has been priced at **0% YES**.[1][9][11]

For context, that zero probability is best read as a statement about the market’s current information set, not as a forecast of impossibility. Late-July Seoul weather is often volatile because monsoon season can produce abrupt changes in cloud cover, rainfall and humidity, and the clearest day of the month is often near the end of July.[11][18] Comparable summer cases in Korea show that strong heat can build quickly when clear skies persist, with Seoul highs around 34°C and other regions higher still, while Incheon’s airport location can differ from central Seoul because coastal influences can moderate or delay peak heat.[2][16]

A trader should watch the official airport-day reading on Wunderground, plus any short-term updates from the Korea Meteorological Administration and major forecast providers that may signal cloud bursts, sea breeze shifts or rain timing before the midday settlement cut-off.[3][14] On accessibility, Germany’s GlüStV framework is relevant because it can restrict or block some online gambling-style products for German residents, while US CFTC reach matters because American users may still face jurisdictional limits even if the market is accessible elsewhere. “No-KYC up to $1,500” means a user may be able to open and use the market with reduced identity checks until cumulative activity passes that threshold, which improves access but does not remove location-based or legal restrictions.
