Highest temperature in Seoul (Incheon) on August 20?

Platform comparison

Market context

On 20 August 2026, Seoul's Incheon International Airport weather station will record a daily maximum temperature in Celsius. The market resolves to whichever temperature band contains that figure, with Weather Underground's Daily Observations table serving as the authoritative source rather than summary displays that occasionally diverge from raw station data. August represents Seoul's peak summer season, with historical August averages near 29°C, though individual daily highs frequently exceed 32°C during heat waves.

The 0% crowd probability reflects genuine uncertainty about which specific temperature band will occur rather than doubt about whether a reading will materialise. Historical precedent from comparable weather markets shows that summer temperature ranges in East Asia attract modest trading volumes until late July, when seasonal patterns crystallise and traders gain confidence in narrow band predictions. Seoul's August temperatures have ranged from 23°C on cooler days to 38°C during extreme events over the past two decades, creating a wide resolution space. The Korea Meteorological Administration typically issues extended forecasts by early August, which often trigger repositioning in weather derivative markets.

Traders should monitor tropical cyclone activity in the Western Pacific during mid-August, as typhoons can suppress temperatures significantly. The East Asian monsoon pattern and any anomalous high-pressure systems over the Korean Peninsula will prove decisive. Historical data from Wunderground's Incheon station shows consistent recording protocols, minimising settlement disputes, though traders should verify the specific temperature band definitions before committing positions.

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.

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.

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.
