For sightseeing, the weather is normally best in May, June and September, although this is not guaranteed.
In the summer, the weather is warm and traffic less intense. But the top attractions are crowded and city life is at a minimum, specially between August 1st and 15th.
We advise you to stay a minimum of two days in Paris if you can and want to see the top sights. As there is so much to see, a guided sightseeing tour is a fast and convenient way of discovering most of the city the first day.
Your trip to Paris will stay in your memory for ever.
You have 7 hours at Charles de Gaulle Airport: try our 4 hour Paris walking tour or visit Charles de Gaulle Airport Shopping Mall. You have one day: take a one day guided tour to see the most of the city. You have two days: take a guided tour the first day. Spend the second day focusing on what you prefer: shopping, sightseeing, nightlife.
