Highest temperature in Seoul on July 15?

Platform comparison

Market context

Seoul faces its peak summer heat on 15 July 2026, with the Incheon International Airport station serving as the official benchmark for the highest temperature recorded in degrees Celsius. The market currently prices the YES outcome at 0%, implying the crowd believes the temperature will fall outside the specific range offered, likely due to expectations of a cooler day or a mismatch in the range definition.

Historically, mid-July in Seoul sees average highs near 28°C, though heatwaves have pushed readings above 35°C at Incheon in recent years, such as the 36.2°C peak recorded in July 2023. The 0% probability suggests traders are either betting on a significant cool front or that the range set is implausibly high, given that even extreme events rarely breach 38°C at this coastal station.

Traders should monitor the Korea Meteorological Administration’s daily forecast updates and the 5-day high-resolution model runs for the Seoul region, which often shift significantly 48 hours before the event. A recent analysis from Yonhap News highlighted an emerging subtropical ridge pattern that could intensify heat, though no official heatwave advisory has been issued yet for 15 July. On Polymarket, positions settle in USDC on Polygon using conditional tokens, meaning liquidity remains thin until the final forecast confirms the ridge’s trajectory.
