Highest temperature in Seoul (Incheon) on August 1?

Platform comparison

Market context

The event is the highest daytime temperature recorded at Incheon Intl Airport on 1 August, and the live setup has moved from a generic summer forecast into an actual heatwave read on how far the airport can push above seasonal norms. Early-morning readings were already elevated, with Incheon at 26.8°C by 9 a.m. and a national weather report expecting daytime highs of 32–39°C across South Korea, while another report put Incheon’s forecast peak at 34°C for the day. [1][17]

The **0% YES** crowd price is best read against that backdrop: it implies the market is currently treating the relevant temperature band as effectively out of reach, despite a nationwide heatwave and record-breaking conditions elsewhere. Reuters reported South Korea’s highest-ever temperature of 41.4°C on 31 July in Yangsan, showing that the broader synoptic pattern is extreme enough to support outsized highs, but Incheon’s coastal location usually runs cooler than inland and southern hotspots. [8][18] Historical August averages for Incheon are far lower than the current heatwave readings, so a print near the top of the forecast range would be the kind of outcome that can reprice a market quickly.

For accessibility and compliance, the market is best thought of as a weather contract rather than a discretionary sports-style bet, which matters because German GlüStV rules can treat online betting-style products as regulated gambling, while US CFTC jurisdiction can extend to certain event contracts offered to US persons depending on structure and venue. The practical meaning of “no-KYC up to $1,500” for this market is limited access friction: small participation may be possible without full identity verification, but larger deposits, withdrawals, or jurisdiction checks can still trigger onboarding constraints, so traders should assume availability depends on residence, payment rails, and platform policy rather than the headline threshold alone.
