توقع: Highest temperature in Seoul (Incheon) on August 4?

Platform comparison

Market context

Incheon International Airport is set for a severe heatwave day, with local forecasts calling for around 37°C in Incheon and Seoul under mostly clear skies before afternoon cloud increases. Official reporting this morning placed Seoul at 38°C and warned that parts of the capital area would come under a severe heatwave warning from 11 a.m., which is consistent with a market that has to clear in the upper 30s rather than the low 30s.[1][2]

For context, this sits well above the usual August pattern in Seoul, where average highs are typically in the high 20s to around 30°C and the month is normally warm, humid and often rainy. The key market question is whether Incheon Airport actually prints above 37°C before any showers or cloud cover blunt the afternoon peak; in similar heatwave set-ups, airport stations often come in a touch below inland city forecasts, but still comfortably inside the 35°C-plus bands when the warning level is this elevated.[1][14][18]

Traders should watch the first half of the day closely: the hottest reading often arrives before late-day cloud and isolated showers become relevant, and the current warning timing suggests the strongest heat is front-loaded into the midday window.[1][4] If updated forecasts hold at 37°C for Incheon, the live risk is concentrated in whether the airport station matches the headline city forecast or underperforms by a degree or two because of sea influence, local winds, or a slightly earlier convective turn.[1][2][10]

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.

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.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.

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.
