Daytime Highs Reach 11 to 17 Degrees Celsius
Daily Temperature Range to Vary by 15 to 20 Degrees

March 20 is the vernal equinox, when the length of day and night are equal. The weather across the country is expected to be clear, with significant temperature differences between day and night, especially in inland areas.

The morning low on this day is forecast to range from -4 to 6 degrees Celsius. In inland areas, morning temperatures are expected to drop below freezing, leading to the possibility of frost and cold damage, so caution is advised.

The nationwide daytime high is expected to range from 11 to 17 degrees Celsius. In inland regions where temperatures drop below zero in the morning, the daily temperature difference is expected to reach as much as 15 to 20 degrees.

Temperatures will be similar to or slightly higher than the seasonal averages. The clear skies and large temperature differences between day and night are expected to continue through the weekend.

On the east coast and mountainous areas of Gangwon, as well as the northern east coast of North Gyeongsang Province, strong winds with gusts of around 55 km/h (up to 70 km/h in the mountains) are expected through the afternoon of March 20. Swells will also affect the east coast through March 21. High waves may surge forcefully onto the coast and, at times, sweep over rocks, breakwaters, and coastal roads. Precautions should be taken to prevent accidents.
