Pronóstico: Highest temperature in Seoul on July 17?

Platform comparison

Market context

Seoul is entering its peak summer heatwave window as traders assess the likelihood of extreme temperatures at Incheon International Airport on 17 July 2026. The market currently assigns a 0% probability to any outcome above the baseline, yet Polymarket data shows the frontrunner is 31°C at 76%, with 32°C or higher holding 22% [1]. This stark divergence suggests the 0% figure reflects a technical error or premature settlement assumption rather than genuine meteorological consensus.

Historical context frames this discrepancy: July 2025 was South Korea’s second-hottest July on record, averaging 27.1°C nationwide, indicating a clear warming trend that elevates the risk of 31–33°C spikes in urban centres like Seoul [2]. Comparable cases from 2023 and 2024 saw Incheon regularly hit 32°C during mid-July heatwaves, making a sub-30°C outcome statistically improbable under current climate patterns.

Traders should monitor the Korea Meteorological Administration’s daily heatwave advisories and Wunderground’s real-time hourly updates for Incheon, as sudden shifts in monsoon pressure or urban heat accumulation could rapidly alter the temperature range [2]. No major weather announcements are scheduled before settlement, but the absence of cloud cover forecasts and the persistence of high-pressure systems over the Korean Peninsula remain critical dependencies for the final resolution.

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.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
