Highest temperature in Seoul (Incheon) on August 13?

Platform comparison

Market context

Seoul's maximum temperature on 13 August 2026 will be measured at Incheon International Airport Station and recorded in Weather Underground's Daily Observations table. The settlement hinges on this specific data source rather than summary figures, meaning traders must track the granular hourly readings rather than published day-high estimates. Current crowd pricing at 0% suggests either extreme confidence in a narrow temperature band or insufficient liquidity to establish meaningful odds across the full range.

Seoul's August climate is remarkably consistent. Historical data from the past two decades shows daily highs in mid-August cluster tightly between 28–32°C, with readings above 34°C occurring in roughly 15–20% of years during heat-wave conditions. The 2018 heat wave pushed temperatures to 39.6°C in central Seoul, though airport stations typically record 1–2°C lower than city-centre sites. This historical clustering explains why the crowd has priced out extreme outcomes; the real trading opportunity lies in distinguishing between the 29–31°C band (most probable) and the 32–34°C tail (less common but plausible).

Traders should monitor the East Asian summer monsoon pattern through late July and early August 2026, as the timing of the Changma (rainy season) directly affects whether high-pressure systems dominate. The Korea Meteorological Administration publishes extended forecasts from mid-July onwards. Deposit friction via Klarna or SEPA transfers may suppress participation in lower-liquidity temperature bands; deeper book depth typically emerges once traders can fund accounts without minimum thresholds, allowing micro-positions on specific 1–2°C ranges rather than broad buckets.
