Highest temperature in Seoul on June 29?

Platform comparison

Market context

Seoul is bracing for an early wave of extreme heat as June 2026 mirrors the record-breaking patterns seen across South Korea in recent years. The current crowd-implied probability of 24% for a specific high-temperature range reflects uncertainty about whether this year will surpass the historic highs set in 2024 and 2025. In June 2025, 59 out of 97 climate stations nationwide reported new all-time highs for average daily temperatures, with Busan reaching 26.2°C on 30 June—the hottest June day since records began in 1904[1]. The previous national record of 25.8°C, set on 15 June 2024, was broken on 29 June 2025 with 25.9°C, then surpassed again the following day[1]. Seoul itself has previously hit 39.6°C on 1 August 2018, its hottest day in 111 years[5][7].

Traders should monitor real-time data from Wunderground for the Incheon Intl Airport Station, as the market resolves based on the highest temperature recorded at this specific location on 29 June 2026[4]. The key catalyst is whether the early heatwave intensifies to match the 2025 pattern, where Pohang reached 31.6°C and Gwangju hit 29°C during the same period[1]. Any sudden shift in wind patterns or cloud cover could suppress temperatures below the threshold implied by the 24% probability. The settlement window ends at 12:00 UTC on 29 June 2026, meaning the final resolution depends entirely on the peak temperature recorded before that deadline[4]. Watch for updates from the Korea Meteorological Administration, which flagged South Korea as experiencing its hottest summer on record in 2024[2].

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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.

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.
