Highest temperature in Busan on August 18?

Platform comparison

Market context

Busan's weather on 18 August 2026 will be measured by the highest temperature recorded in the Daily Observations table at Gimhae International Airport Station, expressed in degrees Celsius. The market currently shows 0% implied probability, suggesting traders expect the actual high to fall outside the range specified in the settlement criteria. Resolution depends on Weather Underground's primary data source—the Daily Observations table rather than the Day High & Low summary—a distinction that matters when station instruments record multiple peaks throughout the day.

August in Busan typically peaks between 28–32°C, with historical records showing extremes near 35°C during heat waves. The 2018 summer saw South Korea experience temperatures exceeding 39°C in some regions, though coastal Busan moderates slightly due to maritime influence. The current zero-probability reading suggests either the market's temperature range sits well above or below historical norms for this date, or liquidity constraints have left the book unbalanced. Traders depositing via Klarna or SEPA transfers should verify settlement windows align with their funding timelines, as August weather data finalises within hours of the observation period closing at 12:00 UTC.

South Korea's meteorological forecasts typically become reliable 10–14 days ahead. The Korea Meteorological Administration publishes seasonal outlooks in July that can shift trader positioning if they signal anomalous heat or cooling patterns. Watch for typhoon activity in late July or early August—tropical systems approaching the peninsula can suppress temperatures or create sudden spikes depending on timing and intensity. Withdrawal rails like USDC settlement may offer faster capital return than traditional banking if the market resolves quickly after the observation window closes.
