Highest temperature in Seoul on July 5?

Platform comparison

Market context

The market hinges on the highest temperature recorded at Incheon International Airport on 5 July 2026, with current crowd sentiment assigning zero probability to any outcome above the lowest threshold. This stark 0% YES implies traders believe extreme heat is impossible, yet recent data contradicts such certainty. July 2025 was South Korea’s second-hottest July on record, averaging 27.1°C nationwide, while the summer overall reached a new peak of 25.5°C since 1973 [1][3]. Incheon and Seoul routinely see daily highs climb to 85°F (29.4°C), rarely dipping below 74°F (23.3°C) or exceeding 91°F (32.8°C) [2]. Historical extremes include Seoul hitting 37.7°C in early July 2025—the highest in 117 years—proving that record-breaking heat is not just theoretical but recently documented [7].

Traders must monitor immediate weather bulletins from the Korea Meteorological Administration and real-time updates from Wunderground, the official resolution source [4]. A sudden shift in monsoon patterns or an intensifying heat dome could trigger temperatures far above seasonal norms, as seen when Hongcheon recorded 41.0°C in 2023 [4]. Recent reports confirm South Korea endured its hottest summer ever in 2025, with tropical nights persisting longest in 117 years [8]. With settlement ending 12:00 UTC on 5 July, any pre-dawn temperature spike will be decisive. Watch for announcements regarding air quality alerts or emergency cooling measures, which often precede extreme heat events in the region [1]. The zero probability line appears fragile given the trajectory of rising summer temperatures across East Asia.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.
