It was rainy day today.

After correction from native speaker
It was rainy day today so it was very humid. I could not work without the air conditioner. When I came home, I thought my son had finished taing a bath because he had wet hair. My wife endured the humidity without the air conditioner. I immediately turned on it. My son had wet hair from his own sweat!!
