What September feels like
September is when Juneau goes back to being Juneau — the last ships pull out and downtown empties inside a week. The hillsides turn yellow, the rain is relentless, and this is the month locals quietly prefer despite all of that.
This is the wet season: rain on about 17 days, so pack accordingly.
