Paris early February

I've not been to Paris in February but I'd plan for cold and rainy. I'd want a waterproof rain jacket with something like a puffy jacket underneath for warmth. I don't think you will necessarily need waterproof shoes, I usually don't when I am IN Paris. Have a warm hat, scarf and glove liners.

Have you been to Paris before? Asking to know what you might consider off the beaten track.

Gardens will likely be out unless you have some kind of fabulous sunny day!

Are you interested in some of the smaller, perhaps less visited museums/churches?

Any interest in WWII, Medieval Paris, any other time frame?

I'm following this conversation. I am also headed to Paris in Feb. Wanting to get reservations for Notre Dame. When I go to the website for the cathedral the only dates I can click on are The 1st, 2nd. and 3rd of Jan. But all are "sold out".
I can not forward to the month of Feb. Are entry reservations only open 3 days prior?

Jan, indeed, reservations are only open for three days at a time.

Here is a link to a post with information on how to (hopefully) obtain tickets.

The last two times I’ve been in Paris were in February for a two week stay, then the next year at the end of February into March, again for nearly two weeks.
A great time to visit!
I was glad that I had waterproofed my walking shoes, as it did rain a bit and one day I did get absolutely soaked.
I had a hip length winter jacket with a lined hood, a warm hat and gloves and a thick scarf.
All the same clothes I wear here in W. Canada in winter.
I don’t remember it being freezing cold and I am one who really feels the cold.
The one place I felt it was one evening at a concert in Notre Dame.
It did snow one day, but it didn’t stick for long.
I got sick with flu on my first trip, so was glad I had brought a set of silk long underwear to cosy up in till I recovered.
It’s a great time to visit….plenty of warm museums, galleries and cafes to warm up in.
I liked it in Winter much better than in warmer seasons.

Cold, grey, and wet with possible snow. Waterproof shoes (preferably boots) are recommended. I don't use an umbrella, preferring a hat with a brim, but they come in handy.

The regular museums should be a good bet as they will be less crowded, the place of tourists being, in many cases, taken up by school outings.

Off the beaten path? Consider going to Château-Thierry and seeing the WWI monument and the huge American graveyard at Belleau Woods. Into Aviation? The Musée de l'Air et de l'Espace is fantastic and rarely visited. The Carrefour City market is a really good way to get a close look at the differences between American and French supermarkets. (I love to take newbys to them, it's fun just to watch.) If you have a car consider Verdun. Or take a short train ride to Metz or Reims.

There's thread from last month on thrift shops that might interest you. And you may just want to google where the open air markets are on a daily basis.
