Current Weather Situation: A Dual Threat
The Korea Meteorological Administration (KMA) is forecasting continued cloudy conditions and rainfall throughout Tuesday, August 26th, building on precipitation from the previous day. Expected rainfall totals range from 30-80mm in the metropolitan area, with some regions exceeding 100mm. Gangwon inland, mountainous areas, Chungcheong, and Jeolla provinces are also bracing for significant rainfall (20-60mm, potentially exceeding 80mm). Gyeongsang province will see lighter showers (5-30mm), while the east coast of Gangwon will receive around 5mm. Jeju Island is expected to receive 5-40mm over the next two days.
However, the rain isn’t providing significant relief from the heat. Daegu is forecast to reach a high of 34 degrees Celsius even with the showers. Morning lows will range from 23-28 degrees Celsius, and daytime highs from 29-34 degrees Celsius. This combination of humidity and heat creates a dangerous environment, particularly for vulnerable populations.

The combination of high humidity and temperatures also increases the risk of heatstroke. Staying hydrated, seeking shade, and avoiding strenuous activity during peak hours are crucial. “Tropical nights” – where temperatures remain above 20°C – are also expected in urban centers and coastal areas, further emphasizing the need for health precautions.
Did you know? South Korea experiences a distinct monsoon season, typically from late June to early August. However, climate change is leading to more unpredictable weather patterns, including more intense rainfall events and prolonged heatwaves. Understanding these trends is vital for preparedness.
