Highest temperature in Seoul on July 12?

Platform comparison

Market context

Seoul is currently experiencing its peak summer heat on 12 July 2026, with the Incheon International Airport station tracking the day’s maximum temperature in degrees Celsius. The market asks which range contains this peak, yet the crowd-implied probability for a “YES” resolution sits at 0%, suggesting traders expect the temperature to fall outside the offered ranges or doubt the market’s ability to resolve cleanly.

Historical precedent shows Seoul’s July highs frequently breach 30°C, with long-term averages hovering around 28°C and recent records hitting 41.2°C during an exceptionally sweltering July 2025 that included 22 tropical nights [2][5]. The 0% probability likely reflects uncertainty over the specific resolution ranges rather than an expectation of cold weather, as monsoon season typically brings high humidity that amplifies heat stress even when rainfall interrupts peak sunshine [4][6]. Traders should note that Incheon’s coastal location often records slightly lower peaks than inland Seoul, yet extreme heatwaves have still pushed temperatures above 35°C in recent years.

Key catalysts include the Korea Meteorological Administration’s short-range forecasts and real-time Wunderground data for the Incheon station, which will determine settlement [9]. Traders must monitor the timing of the monsoon front: if heavy rain clears before midday, solar heating could spike temperatures rapidly, whereas persistent cloud cover would cap the peak. The Sinchon Water Gun Festival in late July indicates cultural momentum for summer water events, but today’s weather depends entirely on atmospheric conditions rather than human activity [6]. Watch for updates on precipitation probability and wind direction, as light westerly winds combined with high humidity could push the “feels like” temperature well above the recorded dry-bulb value.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
