Highest temperature in Seoul (Incheon) on August 9?

Platform comparison

Market context

Seoul is set up for another very warm day, with forecast highs clustered around **34–35°C** and only scattered shower risk, so the market’s current **0% YES** looks hard to square with the prevailing weather guidance. AccuWeather has Seoul at **93°F** for 9 August with a shower in spots, while Korea Meteorological Administration guidance for the Seoul/Incheon area points to **34–35°C** maximums and continued heat advisory conditions[2][10][12][14].

For context, late-summer highs in Seoul often sit well below this level, so a mid-30s Celsius print would be a meaningful hot-day outcome rather than an ordinary August reading. Comparable daily forecasts from multiple providers are tightly grouped, which matters because this market resolves off the **Daily Observations** record at Incheon Intl Airport Station, not the summary high/low box; that means the traded range depends on the actual observed peak, not the headline forecast number[4][7][10].

The main catalysts are the timing and intensity of any afternoon showers, cloud cover and whether the heat advisory pattern holds through the observation window. Seoul forecasts show possible afternoon precipitation and temperatures still rising into late morning and early afternoon, so traders should watch for any updated KMA short-term bulletins or airport-observation changes that could trim the realised high by a degree or two[2][9][10][12].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

How fast do sports winnings settle?

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.
