Ulsan Sees Byeonsan Windflower Bloom as Weekend Temperatures Swing

In Ulsan’s northern Buk District, the hillside near Hyangtojeonmaeul village is drawing attention as the Byeonsan windflower, a herald of spring, comes into bloom.

Weather officials say the coming weekend will be largely cloudy across the city, with notable temperature swings between morning and afternoon, around 10 degrees Celsius. Residents are advised to dress in layers and monitor health, as rapid changes can affect the vulnerable.

On Saturday, the forecast calls for a morning low of 2°C and a daytime high near 12°C, roughly in line with seasonal averages.

Sunday is expected to be a touch warmer, with an overnight low near 4°C and a high near 14°C.

Air quality is expected to be favorable, with fine dust levels ranging from good to moderate across the region.

Sea conditions along the East Sea front are forecast to run 0.5 to 3.0 meters, while offshore waters within about 200 kilometers of the coast could see waves of 1.0 to 3.5 meters. Those conditions can affect coastal activities and coastal shipping near Ulsan’s port facilities.
