Warm summer breeze, definitely.
I lived in Seattle for two years and I think that's where I fulfilled my lifetime quota of rainy days. And I don't remember the rain ever being warm there...
I did prefer the rain in Seattle to the rain in Atlanta, however. In Atlanta, the rain is NEVER gentle. It's always accompanied by thunder and lightning which terrifies the cats. It can terrify me when I'm caught driving in a particularly heavy downpour.
So yeah, warm summer breeze all the way!
