Highest temperature in Seoul (Incheon) on August 10?

Platform comparison

Market context

Seoul’s late-summer pattern is the key determinant here: August climatology is hot, humid and still capable of producing 30°C-plus afternoons, with World Weather Information Service showing Seoul’s August mean maximum at about 30°C and a typical 10 August high near 34°C.[10] Recent history supports that range of outcomes, with Seoul’s past-week readings already reaching 99°F (37.2°C) and Weather Underground’s Seoul history page showing a current warm, dry profile rather than an early-autumn cooldown.[1][5]

For traders, the important catalysts are the same ones that drive any short-horizon temperature market: overnight cloud cover, morning rain, wind direction off the Yellow Sea, and whether the airport station gets sea-breeze moderation or a stronger inland surge. Weather Underground’s resolution rules make the Daily Observations table decisive, so an intraday spike matters more than the day-high summary if the two diverge.[5] With the market’s current crowd-implied probability still at 0%, the burden is on a genuinely cool day, and the most useful checks are the hourly observation updates at Incheon International Airport and any late-morning forecast revisions from major forecasters such as AccuWeather, which currently points to a high around 93–94°F for 10 August in Seoul.[6][13]

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
