Highest temperature in Seoul (Incheon) on August 12?

Platform comparison

Market context

Seoul's maximum temperature on 12 August 2026 will be recorded at Incheon International Airport Station and resolved against Weather Underground's Daily Observations table. The market currently shows 0% implied probability across all temperature bands, suggesting either insufficient liquidity or a data-loading issue rather than genuine consensus that no temperature will be recorded. August in Seoul typically peaks between 28–32°C, with extreme heat events pushing above 35°C becoming more frequent; the 2018 heatwave saw Incheon reach 38.3°C on multiple days, establishing the upper bound for plausible outcomes.

Historical August temperatures at Incheon reveal a tight clustering: the past decade's daily highs have ranged from 23°C to 37°C, with readings above 34°C occurring in roughly 15–20% of years. The 0% crowd probability likely reflects either market initialisation friction or traders awaiting deposit confirmation through Klarna or SEPA rails before committing capital. Once funding flows activate—particularly from UK-based traders using Klarna's staggered payment option or continental users settling via SEPA—book depth should establish realistic odds reflecting seasonal norms and any emerging weather forecasts.

Traders should monitor the Korea Meteorological Administration's mid-range forecasts (typically issued 7–10 days prior) and track any tropical systems developing in the Western Pacific. Current seasonal patterns favour temperatures in the 29–33°C band, though the market's zero liquidity state means early depositors will face wide spreads until competing positions accumulate sufficient volume to narrow pricing.
