Sun Jun 01 03:50:00 UTC 2025: ## Jeju Swimmers Enjoy Last of Sunny Weather Before Rain Arrives Nationally

**Jeju Island, South Korea** – Swimmers flocked to Hyeopjae Beach on Jeju Island on Tuesday, enjoying the last of the sunny weather before a nationwide rain system arrives. The Jeju Regional Meteorological Administration reported a high of 22.2 degrees Celsius (approximately 72 degrees Fahrenheit) for the island on Tuesday.

However, the good weather is not expected to last. Starting Wednesday, a low-pressure system will bring rain to Jeju and the southern regions of the country, expanding to the central regions overnight. While the rain is expected to clear by dawn on Thursday, Election Day, skies should gradually clear throughout the day.

The Korea Meteorological Administration forecasts daytime highs across the country on Wednesday to reach up to 31 degrees Celsius (approximately 88 degrees Fahrenheit) before the rain arrives. Inland areas are expected to experience a significant daily temperature range of around 15 degrees Celsius (27 degrees Fahrenheit) due to radiative cooling.

Rainfall amounts are predicted to be highest on Jeju (20-60mm), followed by the southern coast of Jeonnam and Busan/Gyeongnam (5-30mm). Other regions, including Gwangju/Jeonnam (excluding the southern coast), Ulsan/Gyeongnam inland, Daegu/Gyeongbuk, and Ulleungdo/Dokdo, can expect 5-20mm of rainfall. Smaller amounts are expected in Gangwon-do, Daejeon/Sejong/Southern Chungnam, Chungbuk, Jeonbuk, and eastern Gyeonggi (5-10mm).

The rain will cause a slight drop in daytime temperatures on Wednesday and Thursday. High winds are also expected, particularly on Jeju on Wednesday and in the mountainous regions of Gangwon on Thursday, with gusts reaching up to 20 meters per second (approximately 45 miles per hour) in the mountains. The seas off the southern coast will also experience strong winds and high waves.

The KMA advises the public to be aware of potential hazards due to the strong winds and high seas and to take precautions against the significant daily temperature range in inland areas.
