Recent official forecasts from the Korea Meteorological Administration align closely on a daily maximum temperature of 25°C in Seoul today, May 17, driving the market’s near-certain consensus at that exact threshold. Mid-May climatological patterns typically feature progressive warming from solar insolation and southerly flow, with current model runs showing minimal deviation around this peak under stable high-pressure conditions. Traders price in this outcome based on real-time observational data and ensemble guidance that places the high squarely at 25°C rather than adjacent buckets. While the probability exceeds 90 percent, a late-day shift in cloud cover, stronger afternoon winds, or slight model bias toward cooler advection could still nudge the official reading one degree lower or higher before final verification.
