Highest temperature in Seoul on June 5?

Market context

The market seeks to establish the highest temperature recorded at Incheon International Airport on 5 June 2026. Seoul's early June climate typically features warm, humid conditions as the region transitions into the East Asian summer monsoon season. Historical data shows June temperatures in the Seoul metropolitan area commonly reach 25–30°C, with occasional peaks above 32°C during heat waves, though such extremes remain less frequent in early June than in July or August.

The 0% crowd probability suggests traders expect the settlement range to fall below whatever threshold defines the lowest option available. This disconnect warrants scrutiny of the specific temperature brackets offered. Early June in Seoul historically produces highs in the mid-to-upper 20s Celsius under typical conditions, with variability driven by whether high-pressure systems establish themselves early or monsoon moisture dominates. Comparable years show considerable year-to-year variation; the Korea Meteorological Administration's historical records indicate June 5 temperatures have ranged from approximately 18°C to 31°C across recent decades.

Traders should monitor seasonal forecasts released by the Korea Meteorological Administration in May 2026, which typically indicate whether early summer will trend warmer or cooler than the 30-year normal. The timing of the East Asian summer monsoon onset—typically mid-June but occasionally earlier—will influence atmospheric conditions. Any significant heat dome or ridge of high pressure establishing itself over the Korean peninsula by early June would push temperatures toward the upper end of the range, whilst an early monsoon surge would suppress highs into the low-to-mid 20s.

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?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.
