how long can this last?

It's been mercifully cool, with low humidity, over the past week or so here in Seoul. I suspect the other shoe is going to drop, and we'll be back to oppressive heat before long. September is normally a hot month, and things don't truly cool down until about mid-October. So I don't think we're experiencing the leading edge of fall; this is more like some cool front that's hanging over us, but which will eventually move on, allowing summer to return in all her wrath. Then again, if this really is a bizarrely early fall, I welcome it. Korean autumn is normally so brief, which is a sad thing, given how beautiful it usually is.
