Unlike yesterday (June 20), which was cool with rain and wind, today, the summer solstice, has seen temperatures return to their seasonal averages.

Early summer heat is expected to continue for the time being.

In the Jeju region, light rain of around 5mm will continue until this evening before stopping. From Monday morning through the night, a pressure trough will approach, bringing between 20mm and up to 60mm of rain.

Showers are also forecast for inland regions.

They are expected to fall heavily, particularly between the afternoon and evening when atmospheric instability is high.

The showers will be accompanied by gusts of wind, thunder, and lightning. In northern Gyeonggi, central and northern Gangwon inland areas, and mountainous regions, hail or graupel may also fall.

Let's take a look at the satellite imagery.

A high-seas warning is in effect, centered around the East Sea.

Strong winds are expected to continue through tomorrow, and high waves are anticipated, so vessels navigating or operating in the area need to exercise extra caution.

Strong swells will also roll in along the east coast.

Please be mindful of safety accidents in coastal areas.

Looking at tomorrow's temperatures, the morning low will be 20°C (68°F) in Seoul and 19°C (66°F) in Daegu. Daytime highs will rise to 28°C (82°F) in Seoul and 25°C (77°F) in Gwangju.

Rain is forecast for Wednesday, mainly in the Jeju region.
