Paris When to Go : As the old song says, Paris is at its best in springtime, even if it is sometimes a little wet. In winter Paris has all sorts of cultural events going on, while in summer the weather is warm and lazy - sometimes sizzling. In August, when Parisians flee for the beaches to the west and south, many restaurateurs lock up and leave town too, but this is changing rapidly and you'll find considerably more places open in summer than even a decade ago. Things can get a bit hectic around Bastille Day and towards the end of the year so reservations at this time are a good idea.
