Highest temperature in Seoul on July 24?

Platform comparison

Market context

The event here is the **highest temperature recorded at Incheon International Airport Station on 24 July 2026**, which is the settlement variable for this market, not Seoul city centre itself. With the market currently showing **0% YES**, the implied pricing says traders are treating a qualifying warm reading as extremely unlikely, so any movement will depend on the day’s actual afternoon maximum reaching the relevant Celsius band on Wunderground’s station history page.

For context, July in South Korea is normally hot, humid and rain-affected, with average highs often near 30°C and frequent monsoon showers, while Seoul’s July rainfall is substantial enough to suppress extremes on many days.[2][3][5] Current market pricing on Polymarket also shows the low-end buckets leading, with **22°C or below** and **23°C** both at 19%, which is consistent with a base case that leans cool rather than heat-spike territory.[1] For a programmatic trader, that makes the market behave like a live weather-data scrape: monitor the station-specific maximum, not city averages, and map the reported value to the settlement range only after the day has completed.

The main catalyst is whether rain over the Seoul–Incheon area keeps daytime temperatures pinned down or clears early enough for heating to build later. A recent Korean weather report said rain was still expected across the capital region on 24 July, with daytime highs nationwide forecast in the high-20s to high-30s and “full-fledged scorching heat” only building later next week.[4] That kind of setup matters for bots, conditional orders and copy-trading logic because the trade is sensitive to timing: a wet morning can still settle into a warmer afternoon if cloud cover breaks, so the useful workflow is to track the hourly observation trail and the final daily max rather than headline forecasts alone.
