What is this water falling from the sky in summer?

Ok, California people, check this out, and let yourself gloat a bit:

In addition to the high temperatures and constant rain, the humidity is almost always over 90%. (at the time I posted this)

At least the rain washes off the sweat.

Korea people, take a look at this, and wonder why you aren't living in California:

Hmmm. Where I come from, summer means sunshine. Rain is not allowed in summer in California. And dry heat rules, I don't care what anyone says.

I would like to take every travel book and website I read about Korea that said "Korea has four distinct seasons," (which they ALL do) and replace it with this:

"Korea has shitty weather most of the year."
