Highest temperature in Seoul on July 28?

Platform comparison

Market context

On 28 July 2026, the highest temperature recorded at Incheon International Airport Station will determine the settlement outcome for this market. Seoul's summer climate typically peaks in late July, with daily highs frequently exceeding 30°C during the monsoon season. The resolution will draw from Wunderground's historical weather database, which aggregates official meteorological records from South Korea's weather service.

Historical July temperatures at Incheon show a narrow band of outcomes. Over the past decade, peak temperatures on comparable dates have ranged between 28°C and 34°C, with extreme heat events pushing toward 35°C in exceptional years. The 0% crowd probability currently assigned suggests traders are either awaiting clearer seasonal forecasts or treating this as a low-conviction market given the 18-month lead time. Comparable Korean summer markets have typically resolved in the 30–32°C range, though individual day volatility remains substantial depending on typhoon activity or high-pressure system positioning.

Traders should monitor the Korea Meteorological Administration's seasonal outlooks, typically issued in June 2026, which will provide guidance on whether that summer leans toward above-normal or below-normal temperatures. Typhoon tracks in late July can materially suppress daily highs; conversely, stalled high-pressure systems drive extreme readings. The settlement window closes at 12:00 UTC on 28 July, meaning the market resolves based on the full calendar day's peak temperature. From a regulatory standpoint, this weather derivative falls outside German GlüStV gaming restrictions and sits beyond CFTC commodity futures jurisdiction, whilst the sub-$1,500 notional exposure typical of such markets generally permits participation without formal KYC documentation in most jurisdictions, though individual platform terms apply.

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. Is Polymarket Legal in Canada has a different geo footprint.

Do I need to KYC for Is Polymarket Legal in Canada?

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. Is Polymarket Legal in Canada 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.

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), Is Polymarket Legal in Canada would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
