Highest temperature in Seoul on July 23?

Platform comparison

Market context

Seoul’s late-July heat is usually enough to keep the market centred in the high-20s Celsius, with the current book leaning to **27°C** and **28°C** the main alternative. That fits the broader July climate profile: average daytime highs in Seoul are around 28°C, with warm, humid conditions and a meaningful chance of rain even in midsummer.[1][3]

The clearest historical frame is that South Korea has already been running hot into the summer, with July 2025 ranked the country’s second-hottest July on record by the Korea Meteorological Administration.[2] That does not lock in a repeat, but it supports the idea that small shifts in cloud cover, humidity and wind can decide where the day’s maximum lands, which matters in a market sitting so close to the 27°C/28°C boundary.[2][3]

For traders, the key catalysts are the local forecast trend into the morning and any change in rain timing, since showers or thicker cloud cover can cap the high below the market’s upper cluster. The market resolves from the highest temperature at Incheon Intl Airport Station on the day, so the exact station reading matters more than city-wide averages; the main live watchpoint is whether the day opens under stronger sunshine or with early cloud and precipitation risk.[3]

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.

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.
