Fog and winter at the airport
Roissy counts 40.1 fog days a year on average. Fog is a winter feature: November has 6.8 fog days, December 7.0 and January 6.7. In July the average is 0.8. About half of the year's fog days fall in those three winter months.
These are climate averages. They are not a forecast for your departure day and they say nothing about delays. Check the forecast and your flight status shortly before you leave, and allow extra time on foggy mornings if you have a tight connection.
Snow does not appear in the table, but winter temperatures stay close to freezing at night. Highs of 7.0 to 8.2 °C are normal from December to February, so a warm coat is enough for a day in Paris.

Highs of 22.6 to 25.1 °C and lows of 13 to 15 °C. The Air and Space Museum stays open until 18:00 from April to September, and warm days suit a walk through the old town of Senlis.
