Pronóstico: Highest temperature in Seoul on July 10?

Platform comparison

Market context

Seoul is currently experiencing extreme heat, with temperatures reaching 37.8°C on 8 July, the highest ever recorded in the city during the 1–10 July window since records began[1]. This event frames the current 0% YES probability for a higher temperature on 10 July 2026, as the historical ceiling for early July has just been breached. While July averages in Seoul typically hover between 25–30°C with occasional spikes near 30°C, the 2026 forecast shows daily highs ranging from 82°F to 95°F (27.8°C to 35°C), with an average high of 87°F (30.6°C)[2][4]. The all-time Korean heat record of 41.0°C occurred in Hongcheon, not Seoul, and the city’s highest early July temperature in 117 years was 37.7°C, just 0.1°C below the current peak[6][7].

Traders should monitor real-time Wunderground data for the Incheon Intl Airport Station, as the market resolves based on the highest temperature recorded at that specific location on 10 July 2026, not Seoul city centre[1]. Key catalysts include sudden shifts in humidity, which can elevate the “feels like” temperature and push actual readings higher, as well as the timing of afternoon heatwaves that typically peak between 2–4 pm[4]. Recent reports confirm South Korea is enduring record-breaking summer heat, with the country recording its second-hottest July since 1973, suggesting sustained high-pressure systems may persist through mid-July[8]. Any announcement of a typhoon or heavy rain system approaching the region could drastically lower temperatures, but current conditions point to continued scorching heat[10]. The settlement window ends at 12:00 UTC on 10 July 2026, so traders must watch for the final hourly readings before that cutoff.

FAQ

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.

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.
