Highest temperature in Seoul (Incheon) on August 2?

Platform comparison

Market context

The relevant event is the **day’s highest temperature at Incheon International Airport Station**, which the market will settle from Wunderground’s daily history page. At 06:00 UTC, the crowd is leaning towards a *low-30s Celsius* outcome, with 32°C the frontrunner at 42% and 33°C next at 30%, while 34°C is priced much lower at 5%[1]. That shape is consistent with a hot but still fairly bounded summer range for the Seoul-Incheon area, where humidity and the coastal position usually keep the airport station a little cooler than the most extreme inland readings.

Recent comparable readings suggest the current 0% YES view is too absolute for a market with live summer heat risk. Polymarket’s own market text cites Korea Meteorological Administration expectations of a daytime peak near 32–33°C for Incheon/Seoul, while other local reporting put Incheon around 33°C and Seoul around 35°C as the heatwave broadened across the capital region[1][4]. Incheon has also tended to trail the sharpest national spikes, even as South Korea has just seen record-breaking heat elsewhere, including a 41.4°C national high in Yangsan on 31 July[10][2]. For pricing, that means the book depth is likely to follow how tightly traders can fund and recycle positions rather than any single dramatic headline.

The main catalysts are the morning and afternoon KMA updates, plus any change in cloud cover, sea breeze, or rain timing that would cap the airport’s maximum before the settlement window closes[5][9]. Traders also watch for whether the broader heatwave persists after the recent record-setting conditions, because continued national warnings can pull more flow into temperature markets[2][10]. In practice, this kind of contract tends to tighten when deposit rails are smooth: fast on-ramps such as **Klarna**, lower-friction **SEPA** transfers, and cheap **USDC** funding all help fresh capital enter quickly, which can widen depth around the most likely 31–34°C buckets rather than leaving the market thin.
