Highest temperature in Seoul (Incheon) on August 16?

Platform comparison

Market context

Seoul's Incheon International Airport will record a daily high temperature on 16 August 2026, measured at the official meteorological station. The market resolves based on the highest reading in Weather Underground's Daily Observations table—the granular data feed rather than the rounded summary figure—ensuring precision in settlement. This distinction matters; intraday spikes often appear in raw observation logs before being smoothed into headline figures.

Seoul's August climate is remarkably consistent. Historical data from the Korea Meteorological Administration shows that mid-August highs cluster between 28–32°C, with extreme readings above 35°C occurring in roughly one in five years during heat waves. The 0% crowd probability suggests traders are pricing in a specific threshold that sits well above the seasonal norm—likely 35°C or higher. This reflects the rarity of such extremes rather than any forecast certainty; August 2026 remains two years distant, and seasonal models carry substantial uncertainty at that horizon.

The relevant catalysts are the East Asian monsoon pattern and any developing tropical systems. The Korea Meteorological Administration publishes extended outlooks in June and July 2026 that will sharpen expectations around atmospheric circulation. Traders monitoring Pacific typhoon activity and upper-air ridge positioning in late July will gain early signals; a stationary high-pressure system over the Korean peninsula typically drives the most extreme heat. Deposit flows into the market will likely spike in early August as forecasts crystallise and traders position ahead of the settlement window.
