Highest temperature in Seoul on July 25?

Platform comparison

Market context

Seoul's peak temperature on 25 July 2026 will be measured at Incheon International Airport Station and resolved against historical weather data from Wunderground. July is Seoul's warmest month, with typical highs between 28–32 °C, though heat waves can push readings above 35 °C. The settlement window closes at midday UTC on 25 July, meaning the full day's temperature range must be recorded before resolution.

Historical precedent shows Seoul experiences extreme heat variability in late July. The city recorded 39.6 °C on 24 July 2023 during a severe heat wave, yet typical years see peaks 5–7 °C lower. The 0% crowd probability suggests traders are pricing in either confidence in a specific temperature band or uncertainty about which range will ultimately contain the day's high. Comparable markets on East Asian summer temperatures have historically resolved across wide bands; Seoul's urban heat island effect and proximity to Incheon's coastal location create measurable microclimatic differences that affect final readings.

Traders should monitor Korea Meteorological Administration forecasts released in early July 2026, which typically provide 10-day outlooks by mid-month. Typhoon activity in the Western Pacific during late July can suppress temperatures significantly, whilst high-pressure systems over the Korean Peninsula drive sustained heat. Real-time weather station data from Incheon becomes the critical dependency once the settlement date arrives; Wunderground's historical records are updated daily and serve as the binding resolution source.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal UK?

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
