Paris in January.  A bit dark and gloomy.  But probably better than Paris in July, all things considered.  April in Paris... well, that's a song (and Count Basie album).  Shoulder season is off limits for us because we teach.  So we generally travel when everyone else does - during the summer.  We visited cities that were hot and crowded.  Until recently.  For the second year in a row we decided to travel to Europe in January, in between semesters, the low-low season.  The weather in Paris this January was pleasant if one wore a jacket and didn't mind overcast skies.  The outdoor cafes were still open and plenty busy.   But the tourist/cultural attractions were pleasantly mob-free.  Is Paris still Paris in January?  I'm pretty sure it is.
