The market's near-certain positioning on 30°C for Busan's daily maximum today reflects the latest ensemble forecasts from regional meteorological models, which project peak afternoon temperatures under stable high-pressure conditions and light southerly winds. Morning observations already show readings climbing into the upper 20s, consistent with a seasonal anomaly driven by suppressed cloud cover and above-average sea surface temperatures in the Korea Strait. Historical May baselines for Busan center near 22–24°C, underscoring how today's synoptic pattern supports this specific threshold without crossing into higher ranges. Minor uncertainties remain around localized sea-breeze timing or brief convective development that could trim the final reading by 1–2°C before official close-of-day verification.
