Highest temperature in Seoul (Incheon) on August 15?

Platform comparison

Market context

Seoul's weather on 15 August 2026 will be measured by the highest temperature recorded at Incheon International Airport Station, with settlement determined by the Daily Observations table on Weather Underground rather than summary figures. August in Seoul typically sees peak summer heat, with historical highs often exceeding 30°C and occasionally reaching 35°C or above during heat waves. The 0% crowd probability suggests traders currently see little conviction in any specific temperature band, likely reflecting uncertainty about which range the market has defined and the distance of the forecast window.

Seoul's August temperatures have shown considerable year-to-year variation tied to monsoon patterns and Pacific typhoon activity. The 2018 heat wave pushed temperatures above 39°C in parts of South Korea, whilst cooler Augusts have seen highs around 28–30°C. Incheon, as a coastal station, typically runs 1–2°C cooler than central Seoul due to maritime influence. Historical records from the Korea Meteorological Administration provide the baseline for understanding what constitutes an outlier versus a typical August day in the region.

Traders monitoring this market should track seasonal weather forecasts released in July 2026, particularly from the Korean Meteorological Administration and international models indicating El Niño or La Niña conditions. Typhoon activity in the Western Pacific during early-to-mid August will be the primary catalyst affecting actual temperatures; a system passing near Korea could suppress highs significantly, whilst a high-pressure system would favour extreme heat. Deposit friction via Klarna or SEPA transfers may influence order flow depth as traders position ahead of the settlement window, with USDC rails offering faster execution for those already funded.
