Highest temperature in Seoul (Incheon) on August 11?

Platform comparison

Market context

Seoul's summer heat in early August typically peaks between 28–35°C, with occasional spikes above 36°C during heat waves. The Incheon International Airport weather station, which serves as the official observation point for this market, has recorded August highs ranging from 26°C in cooler years to 38°C during extreme heat events. The 0% crowd probability suggests traders currently expect the temperature to fall outside the uppermost range bracket—a positioning that reflects either confidence in moderate conditions or liquidity constraints limiting participation in Seoul weather markets.

Historical August data from Incheon shows considerable year-to-year variance. The 2018 heat wave pushed temperatures to 38.4°C; conversely, 2020 saw a cooler August averaging around 29°C. The distinction between Weather Underground's Daily Observations table and its Day High & Low summary matters operationally: the former captures sub-hourly readings and typically reflects the true peak, whilst the latter can lag or smooth data. This technical specification affects how traders should weight recent station calibration changes or reporting delays.

The settlement window closes mid-day on 11 August 2026, giving traders roughly eighteen months to monitor seasonal forecasts and deposit capital. Payment friction remains material: traders funding via Klarna instalments or SEPA transfers should account for settlement delays when positioning, whilst USDC on-ramp availability determines how quickly large positions can be deployed. Book depth in Seoul weather markets historically correlates with broader Asian market activity; sustained inflows from UK-based traders using alternative payment rails would likely tighten spreads and shift implied probabilities away from the current extremes.
