Highest temperature in Seoul (Incheon) on August 11?

Platform comparison

Market context

Seoul's summer heat in August regularly exceeds 30°C, with daily highs frequently reaching 32–35°C during the peak monsoon season. The 11th of August falls within the most intense period of Korean summer, when Pacific high-pressure systems and tropical moisture converge over the peninsula. Historical records from Incheon International Airport—the official observation point for this market—show August averages around 29°C, though individual days commonly spike 3–5°C above that mean. The 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a baseline calibration ahead of the 2026 summer season.

Comparable August temperature markets in East Asia have resolved across the full spectrum of offered ranges, with outcomes heavily dependent on whether tropical cyclones or stationary fronts dominate the week in question. The Korea Meteorological Administration publishes 10-day forecasts each Friday; the final update before 12 August 2026 will be the most actionable signal for traders. Monsoon onset timing, intensity of the Pacific anticyclone, and any typhoon activity in the region between 5–11 August will determine whether temperatures cluster in the 28–30°C band or breach into the 33–35°C territory typical of Seoul's hottest years.
