It's been so mild this winter that we've gone without heat until just lately. In fact, the heat's not on now, at ten minutes to midnight on December 29th. Amazing.
Tokyo winters are never terribly cold (compared to Chicago or Pittsburgh, that is) but this one seems warmer than average. Could be my imagination, but November into early December seemed warmer and wetter than usual. We're finally getting typical crisp, clear December days but it seems like they came a few weeks later than usual.
Weather's a little tricky to recall. I could be just misremembering past years. But according to this nifty page from the Japan Meteorological Agency I'm not off base. http://www.data.kishou.go.jp/normal-e/mrep_e.html
December's data's not in yet (of course) but I be it will be warmer and wetter than usual.
"... it will be warmer and wetter than usual."
Sounds ideal.
