Highest temperature in Seoul (Incheon) on August 13?

Platform comparison

Market context

On 13 August 2026, Seoul's Incheon International Airport weather station will record a daily maximum temperature in Celsius, with settlement determined by the highest reading captured in Weather Underground's Daily Observations table rather than summary figures. The market currently shows 0% probability, suggesting traders expect the temperature to fall outside whichever range option represents the upper threshold being tested.

Seoul experiences peak summer heat in mid-August, with historical August averages around 29–30°C, though daily highs regularly exceed 32°C during heat waves. The city's August 2023 maximum temperatures ranged from 28–35°C across the month, whilst August 2022 saw several days above 33°C. Incheon's coastal location moderates extremes slightly compared to central Seoul, but the airport station still captures typical summer conditions. The 0% crowd probability suggests the market may be pricing in either an unusually cool day or that the specified temperature threshold sits well above typical August conditions.

Traders should monitor long-range weather forecasts from late July 2026 onwards, particularly tracking whether high-pressure systems or typhoon activity influence conditions in early-to-mid August. The Korea Meteorological Administration typically issues 10-day outlooks by early August. Settlement hinges entirely on Weather Underground's Daily Observations table methodology—specifically how the station records sub-hourly temperature peaks—making data source consistency critical. Any station maintenance or sensor recalibration near the resolution date could affect readings.

FAQ

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

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.

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.
