I hate to say it but the Paris weather is not always sunny. On average it rains 171 days per year, during a total of 548 hours - the rain is pretty well distributed over the year (even though the dryest season is spring). Snow is pretty rare (15 days on average) and so is the wind (44 days per year). Now the good news! In Paris, on average, the sun shines 1 798 hours per year.
