According to the Korea Meteorological Administration, the central region will be mostly cloudy tomorrow, while the southern regions and Jeju Island will see occasional clouds.

Inland areas of northern Gyeonggi and northern Gangwon may experience showers in the afternoon, with precipitation ranging from 5 to 20 millimeters. The five West Sea islands are also expected to receive about 5 to 20 millimeters of rain.

In areas where showers occur, there may be gusty winds, thunder, and lightning.

Morning lows will range from 23 to 28 degrees Celsius, and daytime highs will be between 27 and 36 degrees Celsius, higher than average for this time of year.

With heat advisories issued for most parts of the country, the maximum perceived temperature is expected to reach around 33 degrees Celsius for the time being. Some areas, including parts of Gyeonggi, the east coast and mountainous regions of Gangwon, southern regions, and eastern Jeju Island, may see temperatures rise to 35 degrees Celsius.

On July 2, the daytime high is forecast to reach 36 degrees Celsius in Daegu and Ulsan, 35 degrees in Gangneung, 34 degrees in Jeonju, Gwangju, and Changwon, and 32 degrees in Seoul.

In areas where showers occur, temperatures may temporarily drop, but after the rain stops, humidity will remain high and temperatures will rise again during the day.

Until the morning, dense fog with visibility less than 200 meters is expected along the west coast of Chungnam, the coast of Jeonnam, and the coast of Gyeongnam, which may also result in light drizzle. In other areas, fog may reduce visibility to less than 1 kilometer.

Waves in the seas off the east, west, and south coasts are expected to be 0.5 to 1.0 meters high. In the outer seas (up to about 200 kilometers from the coastline), wave heights are forecast to be 0.5 to 1.5 meters in the East Sea and West Sea, and 0.5 to 1.0 meters in the South Sea.
