Highest temperature in Seoul on July 28?

Platform comparison

Market context

Seoul's peak temperature on 28 July 2026 will be measured at Incheon International Airport Station and reported in Celsius. July is Seoul's warmest month, with historical daily highs typically ranging from 28 to 32°C, though extreme heat events have pushed readings above 35°C in recent years. The 0% crowd probability suggests traders are either uncertain about the settlement mechanism or expect the market to remain unresolved due to data unavailability.

Historical precedent matters here. Seoul experienced a record high of 39.6°C in August 2018, and July 2023 saw multiple days exceeding 33°C as part of a broader East Asian heatwave. Weather prediction markets on specific dates often show compressed probabilities early on because atmospheric conditions remain genuinely uncertain weeks in advance. Comparable markets tracking daily temperature extremes at fixed stations typically see probability distributions widen as the settlement date approaches, with traders incorporating seasonal norms, medium-range forecasts, and any emerging heat-wave signals.

Traders should monitor the Korea Meteorological Administration's monthly outlook, typically released mid-June, which flags anomalous temperature patterns for July. Real-time catalysts include tropical cyclone activity in the Western Pacific—storms can suppress peak temperatures through cloud cover and precipitation—and the strength of the North Pacific high-pressure system, which drives sustained heat. Wunderground's historical data feed for Incheon RKSI has proven reliable for settlement purposes in prior weather markets, though traders should verify the station's operational status ahead of the settlement window closing on 28 July at 12:00 UTC.

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 Tax UK has a different geo footprint.

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.

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).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
