The biggest feature of today's weather is the strong showers that will fall from the afternoon to the night, mainly in the inland parts of the country. This is because the cold air staying in the upper atmosphere meets the sunlight that heats the ground during the day, causing rising air currents, forming showery clouds in various places. About 5 to 40 mm of rain is expected in inland areas across the country, including Seoul and the metropolitan area, and in some areas, it is highly likely that gusty winds will be accompanied by thunder and lightning. In particular, in the mountainous areas of northern Gyeonggi and central and northern Gangwon, there is a risk of hail or hailstones larger than 0.5 cm in diameter falling, so special vigilance is needed to manage facilities and prevent damage to crops. Since precipitation can vary greatly even within the same area, wisdom is required to check real-time weather information.

This is a day that requires extra caution for those visiting the coast and the sea. Currently, a storm warning is in effect centered on the East Sea, and the wind is blowing very strongly at 9 to 18 meters per second and the wave height is also 1.5 to 4.0 meters. In the east coast area, swell waves are expected to surge onto the white sandy beach or over the breakwater and seaside rocks for the time being, so you should refrain from approaching the coast. In the case of Jeju Island, rain of more than 20 to 60 mm is expected to continue from morning to night due to the influence of a trough approaching from Shanghai, China. As maritime safety accidents occur without warning, safety rules must be strictly observed when operating a ship or engaging in coastal activities.

As much as bad weather, what increases citizens' discomfort is the mass appearance of red-backed velvet flies, so-called 'love bugs'. Experts believe that this insect, which is active from mid-June to early July, has recently completely adapted to the ecosystem and is likely to appear repeatedly every year. Adult insects are beneficial insects that help with pollination, but when they occur in large numbers, they stick to car windows or get on clothes, causing extreme discomfort to citizens. Accordingly, major local governments, such as Gyeyang-gu in Incheon and Jongno-gu in Seoul, are doing their best to relieve citizens' anxiety by preparing preemptive response measures such as installing collectors and sticky traps and mobilizing water sprinklers and drones for pest control when necessary.

Looking at air quality and temperature distribution, the concentration of fine dust in most areas of the country is maintained at a ‘good’ level, showing relatively comfortable air quality. However, ozone concentration is predicted to soar to ‘poor’ levels in some areas, including the Seoul metropolitan area and South Chungcheong Province, excluding the northern part of Gyeonggi Province, in the afternoon, so you must be careful about your respiratory health when engaging in outdoor activities. The highest daytime temperature will fluctuate between 21 and 29 degrees, showing a cool temperature distribution similar to or slightly lower than previous years. However, as the atmosphere is unstable, it is necessary to make it a habit to carry a small umbrella in case of sudden rain. Even though it is a time when temperature changes are not large, we must not forget that environmental factors such as ozone and rain showers can threaten our health.
