Highest temperature in Seoul on July 25?

Platform comparison

Market context

Seoul's highest temperature on 25 July 2026 will be measured at Incheon International Airport Station and reported in Celsius. July is Seoul's hottest month, with historical daily highs typically ranging from 28–32°C, though heat waves can push readings above 35°C. The settlement will draw from Wunderground's historical weather database, which aggregates official meteorological records from the airport's monitoring station throughout the day.

The 0% crowd probability reflects genuine uncertainty rather than consensus that extreme heat is unlikely. Seoul experienced a peak of 39.6°C in July 2023 and has seen multiple days exceeding 35°C in recent summers. Comparable East Asian cities show similar volatility: Tokyo recorded 41.1°C in 2021, and Busan hit 40.3°C in 2018. Historical precedent suggests traders should calibrate expectations against the upper tail of Seoul's July distribution rather than dismiss high-temperature ranges as implausible.

Traders should monitor seasonal weather forecasts released by the Korea Meteorological Administration in early July 2026, particularly alerts regarding Pacific high-pressure systems and tropical moisture patterns that drive heat waves across the Korean peninsula. El Niño or La Niña conditions in the preceding months will influence summer circulation patterns. Real-time tracking begins in late June when extended forecasts become more reliable; daily updates from Wunderground become the operative reference only after 25 July itself. No regulatory announcements or policy changes affect the underlying weather event, though market accessibility depends on jurisdiction: UK traders face no KYC requirement up to £1,200 equivalent under Gambling Commission guidance, whilst US participants encounter CFTC restrictions on weather derivatives, and German traders must comply with GlüStV licensing requirements for derivative positions.

FAQ

Do I need to KYC for Polymarket Tax 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.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Tax 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.

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.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
