Highest temperature in Seoul on June 2?

Platform comparison

Market context

Seoul's weather on 2 June 2026 will be measured at Incheon International Airport Station, which serves as the official meteorological reference point for the capital region. Early June typically marks the transition into South Korea's rainy season, with temperatures generally ranging between 20–28°C, though heat waves can push readings considerably higher. The 0% crowd probability suggests traders are either uncertain about the resolution mechanism or expect cooler conditions than historical norms for this date.

Historical data from Incheon shows considerable variability in early June temperatures. Between 2015 and 2024, the highest daily temperatures on 2 June ranged from 19°C to 29°C, with an average around 24–25°C. Years with anomalously warm readings typically coincided with high-pressure systems establishing over the Korean peninsula in late May, whilst cooler years reflected maritime air masses or cloud cover from developing monsoon systems. This spread indicates that temperature ranges spanning 5–10°C intervals would capture most plausible outcomes.

Traders should monitor weather forecasts released in the final week of May, particularly from the Korea Meteorological Administration, which publishes extended outlooks roughly seven days ahead. Atmospheric patterns in late May—including sea surface temperatures in the Yellow Sea and positioning of the subtropical high-pressure ridge—will be critical indicators. Any official heat-wave warnings issued for the Seoul metropolitan area in early June would signal elevated probabilities for higher temperature ranges, whilst tropical cyclone activity in the western Pacific could suppress temperatures through increased cloud cover and precipitation.

FAQ

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.

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.
