Rainning season?

July...It used to be raining season people called in Korea. I like the sound of rainning and getting rain on my body. I enjoyed that weather in Korea, but I do not feel these days. I do not see any rain these days. It just cloudy and a sudden shower....... more like east-Asia country weather it became. What happened to the earth and Korea? Even Korea forecast center does not make any announcement of rainning season officially. It is very difficult to tell when the rainning season begin and finish, because of changeable weather.
