Recent KMA and international model runs indicate Seoul's July 16 minimum temperature—defined as the lowest reading between 3–9 a.m. local time—will likely fall in the 22–24°C range amid typical East Asian monsoon conditions with moderate humidity and variable cloud cover. The market's leading 19°C-or-below bracket at 38% implied probability reflects trader emphasis on potential overnight cooling from increased precipitation chances and recent cooler analogs, such as the confirmed 22°C low on July 7. Updated short-range forecasts showing highs near 31–33°C and variable steering patterns support the clustered probabilities around 21–23°C, while historical July baselines near 21–23°C provide climatological context for the uncertainty. New KMA updates expected within 24 hours could refine these odds.
