Highest temperature in Seoul on July 7?

Platform comparison

Market context

On 7 July 2026, Seoul will experience peak summer heat, with long-term averages suggesting daytime maximums near 28°C, though humidity can push the “feels like” temperature well over 34°C by midday. This is the heart of the monsoon season, where short but intense rainfalls dominate, yet high temperatures often persist even after showers clear the streets.

Historically, July in Seoul sees average highs hovering in the upper 20s, occasionally nudging 30°C, with the hottest day of the month typically reaching 31.9°C. The current 0% YES probability on Polymarket implies the market expects the temperature to fall below the threshold defined for a “YES” outcome, likely a range above 30°C. Given that 30°C is an upper-bound average rather than a guaranteed daily peak, and that rain can suppress temperatures, this pricing aligns with comparable years where July highs stayed below 30°C despite humid conditions.

Traders should monitor the Korea Meteorological Administration’s short-range forecasts, which currently show a 40% chance of precipitation and a daily high of 31°C, as well as any updates from Wunderground on the Incheon Intl Airport Station. A sudden shift toward prolonged overcast spells or heavy rainfall could suppress temperatures below the threshold, while a dry, high-pressure spell could push them higher. The Sinchon Water Gun Festival in late July may also influence local humidity and temperature patterns, though its timing is after the settlement window.
