Highest temperature in Seoul on July 15?

Platform comparison

Market context

Seoul is bracing for peak summer heat as traders assess the likelihood of a record-breaking high on 15 July 2026, with the market currently pricing any YES outcome at zero per cent. The settlement hinges on the maximum temperature recorded at Incheon International Airport Station, the official reference point for Seoul’s climate data, rather than the city centre itself. Incheon typically runs slightly cooler than central Seoul due to its coastal location, though both areas experience intense heat during mid-July.

Historical precedent suggests extreme July temperatures are plausible but not guaranteed. In early July 2025, Seoul hit 37.7°C—the hottest early-July day in 117 years and the highest since 1908[1]. That record underscores the city’s vulnerability to climate-driven heat spikes, yet Incheon’s airport station has not matched that intensity in recent years. The current 0% probability implies the crowd expects temperatures to stay well below the 35–37°C threshold that would trigger a YES resolution, despite the 2025 anomaly.

Traders should monitor the Korea Meteorological Administration’s weekly heatwave forecasts and Wunderground’s real-time hourly data for Incheon, as sudden shifts in monsoon patterns or Pacific high-pressure systems could alter the outlook. A sudden spike in humidity or a stalled heat dome over the Yellow Sea could push temperatures higher than models predict. No official heatwave warning has been issued for mid-July 2026 as of early Wednesday, but the window remains open for rapid changes before the 12:00 UTC settlement deadline.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
