Recent forecast model runs from the Korea Meteorological Administration and global ensembles indicate a southerly flow advecting warmer air over the Korean Peninsula, positioning Busan’s expected daytime maximum near 29–31 °C for May 17. This places the market-implied odds for 30 °C at near-certainty, reflecting consensus on peak conditions under stable high pressure and minimal cloud cover. Coastal sea-breeze circulation may provide some moderation, yet current observations at Gimhae International Airport already show morning temperatures near 25 °C with continued warming projected through afternoon. Historical May climatology supports occasional early-summer spikes to this range when synoptic patterns favor advection from the south, though any earlier-than-expected onshore flow could cap the high below the leading outcome.
