Trader consensus on Polymarket reflects Korea Meteorological Administration short-range forecasts and global models like ECMWF and GFS projecting Busan's highest temperature on May 17 near 29-30°C, with 26.5% implied probabilities tied for each amid a high-pressure ridge delivering clear skies and warm southerly flow. This marks a warming trend from recent days' mid-20s highs, fueled by above-normal temperatures across southern Korea, but coastal sea breezes introduce uncertainty—potentially capping peaks at 29°C by enhancing low-level mixing or allowing 30°C if lighter winds prevail. Model ensembles show tight spreads around 29.5°C, with resolution hinging on official KMA station readings; expect volatility from tomorrow's 12z updates as diurnal heating patterns clarify. Historical mid-May norms hover at 22-24°C, underscoring the atypical heat.
