Trader consensus on Polymarket has locked in a 100% implied probability for Busan's highest temperature reaching exactly 24°C today, driven by the Korea Meteorological Administration's (KMA) latest short-range forecast, which projects a daytime peak of 24°C under partly cloudy conditions with light southerly winds and moderate humidity limiting further warming. Current observations from KMA stations confirm morning temperatures climbing steadily toward this cap, consistent with regional ensemble model runs showing minimal convective activity and no heat advection from inland areas—aligning with May climatology where Busan averages highs of 22–24°C. Scenarios challenging this include prolonged solar insolation from unexpected clearing skies or microscale urban heating effects, potentially nudging readings to 25°C; KMA's evening update will provide final observational data for market resolution.
