Highest temperature in Busan on August 18?

Platform comparison

Market context

Busan's weather on 18 August 2026 will be assessed using the highest temperature recorded in Weather Underground's Daily Observations table at Gimhae International Airport Station, measured in degrees Celsius. The resolution methodology prioritises the granular observation data over summary figures, meaning intraday temperature fluctuations will determine the outcome rather than rounded daily highs.

August represents peak summer in South Korea's southern coastal region. Busan typically experiences temperatures between 28–32°C during mid-August, with occasional spikes above 33°C during heat waves. Historical data from the Korea Meteorological Administration shows that extreme heat events—temperatures exceeding 35°C—occur roughly once every three to five years in August at this location. The 0% crowd probability suggests traders are pricing in a scenario where the temperature remains below the lowest available range, though this conflicts with typical August conditions in the region.

Weather forecasting accuracy for specific daily highs degrades significantly beyond ten days. Traders should monitor tropical cyclone activity in the Western Pacific during early August 2026, as typhoons can suppress temperatures substantially. The East Asian summer monsoon pattern and any anomalous high-pressure systems developing over the Korean Peninsula will be critical. Real-time Weather Underground station data becomes reliable only in the final 48 hours before settlement; prior forecasts from the Korea Meteorological Administration should be cross-referenced given potential discrepancies between sources.

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.

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.

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%.
