Highest temperature in Seoul (Incheon) on August 12?

Platform comparison

Market context

On 12 August 2026, Seoul's Incheon International Airport will record a daily high temperature, with this market resolving to whichever Celsius range contains that peak reading. The resolution hinges on Weather Underground's Daily Observations table rather than its summary figures—a distinction that matters when automated systems and manual readings diverge, as they occasionally do during extreme heat events. August is Seoul's hottest month, with historical daily highs typically ranging from 28 to 32 degrees Celsius, though heat waves have pushed readings above 35 degrees in recent years.

The 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a placeholder market pending typical summer patterns. Historical precedent from comparable Korean weather markets shows that crowds tend to underweight August heat until mid-July forecasts materialise, at which point probability distributions sharpen considerably. The 2023 Seoul summer saw multiple days exceed 33 degrees; the 2024 season proved cooler, with fewer extreme peaks. This variance underscores why early-season weather markets often sit at extreme probabilities until meteorological data becomes more granular.

Traders should monitor the Korea Meteorological Administration's monthly outlook, typically released in late July, which flags whether August 2026 is expected to track warmer or cooler than the 30-year average. El Niño or La Niña conditions, if present, would influence Pacific typhoon activity and upper-air patterns affecting Korean peninsula temperatures. The settlement window closes at noon UTC on 12 August, meaning real-time temperature readings from Incheon Airport become the decisive factor in the final hours.

FAQ

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.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

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.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
