Highest temperature in Seoul (Incheon) on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Incheon International Airport Station will determine this market's outcome. Seoul's summer climate typically peaks in late July and early August, with August temperatures averaging 26–29°C; however, heat waves can push daily highs to 33–35°C. The resolution methodology relies on Weather Underground's Daily Observations table rather than summary figures, a distinction that matters when station equipment logs sub-hourly readings that may differ from rounded daily highs.

Historical August temperatures at Incheon show considerable year-to-year variation. The 2018 heat wave saw readings exceed 34°C on multiple dates; conversely, cooler Augusts have remained below 30°C. The current 0% crowd probability suggests traders expect temperatures to fall outside the highest range bracket offered, though this reflects either extreme confidence in a moderate outcome or insufficient liquidity rather than meteorological certainty. Comparable Korean summer markets have resolved across the full temperature spectrum, indicating that August 15 specifically carries no inherent bias toward anomalous heat or cool conditions.

Traders should monitor the Korea Meteorological Administration's seasonal forecasts and any El Niño or La Niña signals from June onwards, as these influence Pacific typhoon activity and upper-air patterns affecting the Korean peninsula. Real-time tracking becomes relevant from early August when medium-range models stabilise. From a regulatory standpoint, this market falls within the German GlüStV framework for non-licensed operators offering prediction contracts; US CFTC reach applies if US persons participate, though no-KYC access up to $1,500 notional exposure typically permits retail engagement without identity verification on platforms complying with offshore licensing structures.

FAQ

Do I need to KYC for Is Kalshi Legal in California?

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?
