In brief
Meteorological data released by Yonhap forecast variable temperatures and precipitation probabilities across South Korea on Sunday. Seoul and several mid‑peninsula cities face moderate chances of rain, while Busan, Daegu, and Jeju expect bright, warm weather. Residents can use these details to adjust plans for the day.
Short‑range numerical forecasts from South Korea’s national meteorological service have outlined a heterogeneous Sunday weather pattern across the country’s 12 largest cities. The report, released at 9:01 a.m. local time, lists temperature ranges, surface conditions and the probability of precipitation for each city, offering a clear snapshot of what residents might expect as they head out for the day.
Temperature Ranges and Surface Conditions
Temperatures on Sunday fall between 10 °C in the north‑eastern province of North Chungcheong and 22 °C near the volcanic island of Jeju. The forecast specifies a high‑low range for each locality: for example, Seoul’s daytime maximum is projected at 13 °C with a nighttime minimum of 5 °C, while Jeju enjoys a comfortable 22 °C high and 14 °C low. These ranges capture the anticipated diurnal swing caused by prevailing high‑pressure systems and shifting moisture transport across the Korean Peninsula.
Surface conditions vary as well. In the central and northern part of the country — comprising Seoul, Incheon, Suwon, Cheongju, Daejeon and Chuncheon — the predominant pattern is “rain” with signed probabilities ranging from 60 % to 70 %. Conversely, the southern half of the peninsula, including Gangneung, Jeonju, Gwangju, Jeju, Daegu and Busan, is forecast to remain largely “sunny,” with probabilities between 60 % and 70 %. This southeast‑to‑north contrast reflects the influence of a shallow cold front moving from the Korean Demilitarized Zone towards the Sea of Japan.
City‑by‑City Breakdown
Seoul is slated for a high of 13 °C and a low of 5 °C with a 60 % chance of rain. The capital’s weather closely mirrors that of its neighbors, Incheon and Suwon, which also have 60 % rain probabilities and similar temperature ranges (14 °C to 6 °C for Incheon, 12 °C to 6 °C for Suwon). These three cities together form a densely populated zone that is likely to experience a gentle, rain‑laden morning before the afternoon sun clears the skies.
Cheongju registers a 70 % likelihood of rain and a 13 °C high, 6 °C low, while **Daejeon** is marked by a 60 % probability of rainfall, both within the same temperature window as the previous trio. **Chuncheon**, further north in Gangwon Province, records a lower high of 10 °C with a 3 °C minimum, and a 70 % chance of rain, indicating a cooler, wetter micro‑climate that may see reduced sunshine even in the afternoon.
Turning south, **Gangneung** on the east coast enjoys a sunny day with a 60 % chance of clear skies and temperatures of 16 °C high and 9 °C low. **Jeonju** and **Gwangju** also have 70 % probabilities of sunshine, with highs of 14 °C and 15 °C respectively and lows hovering around 6–7 °C. These middle‑peninsula cities are expected to enjoy a reliably bright day, supporting routine outdoor activities such as markets and commuter travel.
The island of **Jeju** stands out with the highest anticipated temperatures: a 22 °C high and a 14 °C low, with only a 60 % chance of sunshine. **Daegu** follows with a sunny forecast and a 60 % probability of clear weather, matching a moderate temperature range of 13 °C/6 °C. Finally, **Busan** forecasts a comfortably warm day with its highest projected temperature of 18 °C and a low of 9 °C, paired with a 70 % sunshine probability.
Implications for Residents
These detailed metrics assist commuters, hikers, and planners in adjusting to an uneven weather picture. The high probability of rain in the northern and central urban core may prompt increased use of umbrellas, wet‑proof transport preparations and brief indoor schedules. Conversely, the sunny southern strip encourages outdoor leisure and may see higher attendance at waterfronts and city festivals.
While the forecast uses “probability” rather than a definitive weather statement, it offers a statistically grounded indication of likely conditions based on atmospheric data pooling. For instance, a 60 % rain probability means that, historically, 60 % of days with similar atmospheric signatures have culminated in measurable precipitation over those cities.
Overall, the Sunday forecast underscores the diverse micro‑climates characteristic of South Korea: a temperate winter climate that can swing from rain‑laden mornings in the province’s heart to clear, warm afternoons along the southern coast. Residents planning their day can now consult the provided temperature windows and precipitation chances to make informed choices about travel, outdoor plans, and wardrobe decisions.
