Highest temperature in Busan on August 17?

Platform comparison

Market context

On 17 August 2026, the highest temperature recorded at Gimhae International Airport Station in Busan will be measured and reported via Weather Underground's Daily Observations table. The market resolves to the temperature range containing that peak reading in degrees Celsius. Busan's August climate typically sees highs between 28–32°C, though tropical systems and heat waves can push readings higher. The 0% crowd probability suggests traders currently expect the outcome to fall outside the upper-bound range specified by this market's resolution brackets.

Historical August temperatures at Gimhae show considerable year-to-year variation. Since 2015, daily highs in mid-August have ranged from 26°C to 34°C, with extreme heat events (above 33°C) occurring roughly once every three to four years during this period. The current 0% probability may reflect either a narrow upper-range threshold or trader uncertainty about whether conditions will align with the hottest possible outcomes. Comparable Korean weather markets have typically seen probability shifts only when seasonal forecasts or active weather systems emerge within two to three weeks of the settlement date.

Traders should monitor the Korea Meteorological Administration's extended forecasts from early August 2026, particularly alerts regarding typhoon activity or heat dome formation over the Korean peninsula. Gimhae's coastal location means sea-surface temperature anomalies and monsoon patterns significantly influence daily maxima. The resolution source's reliance on Weather Underground's Daily Observations table—rather than summary high-low figures—means traders must verify the exact station methodology and any potential data corrections that might occur post-settlement.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Kalshi Legal in California has a different geo footprint.

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
