What kind of weather has the highest air humidity?

Due to the evaporation of raindrops, the air humidity is the highest in rainy days.

Compared with the humidity in rainy days, it is foggy days, especially coastal sea fog. This is because when humid and warm air flows over the colder sea surface, the lower layer will cool down and the air vapor will reach saturation.
