Highest temperature in Seoul on July 25?

Platform comparison

Market context

Seoul's summer temperatures in late July routinely exceed 30°C, with the city's urban heat island effect often pushing daily highs several degrees above surrounding regions. The Korea Meteorological Administration records official temperatures at Incheon International Airport Station, which serves as the settlement reference for this market. Historical data from the past decade shows July 25 highs ranging from 28°C to 34°C, with 2018 and 2022 recording particularly elevated readings near 33–34°C during extended heat waves. The 0% crowd probability suggests traders are either awaiting updated seasonal forecasts or treating the outcome as too uncertain to price meaningfully at present.

Regulatory accessibility differs markedly across jurisdictions. Under Germany's GlüStV (Glücksspielstaatsvertrag), weather derivatives fall outside gaming classification when structured as financial instruments, though prediction markets remain in legal grey territory. US CFTC oversight applies to contracts with US-based participants, though weather markets typically escape direct commodity regulation. Many platforms operate under a no-KYC threshold up to $1,500 notional exposure, meaning traders can access this market without identity verification provided their position size remains modest—a practical consideration for retail participation in niche weather contracts.

The Korea Meteorological Administration publishes 10-day forecasts every morning; the final update before July 25 will arrive approximately 48 hours prior to settlement. Typhoon activity tracking and upper-atmosphere pressure systems warrant monitoring from mid-July onwards, as tropical systems can dramatically suppress daytime highs or, conversely, trap heat beneath descending air masses. Recent years have seen increased volatility in East Asian summer weather patterns, making historical averages less predictive than real-time atmospheric data.

FAQ

Is Polymarket legal in my country?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
