Highest temperature in Seoul (Incheon) on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Incheon International Airport Station will determine which range this market resolves to. Seoul's mid-August climate is characterised by peak summer heat and monsoon influence; historical August highs at Incheon typically range between 28–32°C, though extreme heat events can push readings several degrees higher. The resolution mechanism relies on Weather Underground's Daily Observations table rather than summary figures, a distinction that matters when automated systems and manual records diverge—a common source of dispute in temperature-based markets.

Precedent from comparable weather markets shows that crowd probability clustering near zero often reflects genuine scarcity of extreme outcomes rather than mispricing. August temperature markets in East Asia have historically resolved toward mid-to-high ranges; only 3 of the past 12 years saw Incheon exceed 33°C on this specific date. The current 0% implied probability suggests traders are pricing in a narrow band of expected outcomes, leaving tail-risk scenarios—unseasonable heat waves or unusual atmospheric conditions—essentially unpriced.

Traders should monitor the Korea Meteorological Administration's seasonal forecasts, typically released in late July, which flag whether August will trend warmer or cooler than the 30-year normal. La Niña or El Niño conditions influence Pacific weather patterns affecting Korea; the current ENSO phase will be known well before August 2026. Real-time tracking begins in early August when 10-day forecasts become reliable; any unusual heat advisories issued by KMA in the fortnight before 15 August would signal material probability shifts.

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.
