Location

Gangweon-do is located near the center of the Korean peninsula, while Yangyang-gun is located in the center of Gangweon-do. Its latitude is north 37˚10’41”, while its longitude spans from 128˚22’28” to 128˚55’47”. The 38th parallel passes almost right through the heart of the county. Therefore, the east-west distance of Yangyang-gun is approximately 31km. It is situated most across the Taebaek mountain range having a mountainous terrain. Approximately 74% is situated at an altitude between 100m~1,360m above sea level, while its urban areas are located in areas under 100m. It is a mecca for tourism in which the Outer Seorak at Sokcho, the Inner Seorak at Inje and Southern Seorak at our county unfolds like a painting on a folding screen.

 
Area
The total area of Yangyang-gun is 628.60 km2, of which 535.20km2 (85%) is forestland, 58.6km2 (9%) is farming areas, while 34.8km2 (6%) is classified as others. It has only a small amount of agricultural land, while communities are formed across the valleys of the mountain to have a vast amount of land. On the other hand, it sometimes appears to be narrow because it is surrounded by high mountains, as apparent in the fact that over 85% of the area is made up of forestland.
 
Topography
It stretches out to the East Sea for about 40 kilometers. The Taebaek mountain range is in the west that stretches from north to south and becomes the boundary for Yeongdong and Yeongseo. Seoraksan (Daecheonbong), which is the most celebrated mountain in the Taebaek mountain range, stands 1,708 meters above sea level and has rich tourism resources with its natural environments in mountains and seas. Namdaecheon (Riv.) has its source at Dunobong in Odaesan (Mt.) and flows to the north. It then meets Hucheon and Osaekcheon and flows from southern Yangyang-eub to the northeast and then flows out to the East Sea for 37.1km, making it the longest river in the East Coast.
 
Climate
While Yangyang is situated at the steep slopes of the Taebaek mountain range, it is also located along the East Sea. Therefore, it has an oceanic climate. Its average temperature is 12˚C and its annual range is less than 34˚C, making it have a relatively warm winter and cool summer compared to its latitude.
The annual average rainfall is around 1,300mm making it a high precipitation area of northeastern Korea. In the autumn season, there is approximately 350mm of rainfall and 150mm in the winter time. Thus it has a late monsoon season and blizzards. Its annual average wind speed is 2.9mm/s, and there are 10 days or more of windstorms in a year. There are strong westerlies in the winter and spring season, while the max wind speed recorded was 46.0mm/2 (April 19, 1980), which was the highest recorded wind speed in the province.
Meanwhile, the continuing westerlies create a fan phenomenon and when northeasterly winds flow in, there are severe changes in the weather regardless of the season, and therefore, there is a high chance of accidents that occur due to the weather.
