we'll be in NYC mid December and we usually try to take in a walking tour when we travel. Will it be too cold? Does anyone have a particular walking tour (or tour company) that they recommend? If it is too cold, what other tour (bus, boat, etc.) would you recommend? Thanks.

Weather changes so it's impossible to say now whether it will or won't be too cold. The foodsofny.com walking/eating tour of Greenwich Village is very popular. Bigonion.com does good tours.
2 excellent overview bus tours in enclosed buses are kingofnyc.com and nypartyshuttle.com

You will find some other tours specific to the dates you're here by checking the calendar on nycvisit.com
Here's an exact link since it's not easy to find.

It depends what temps you can handle. I'm from New England, so I know it wouldn't be too cold for me. If you're from the South and don't plan on packing/wearing a coat, it might be too cold for you.

Are you talking about walking in NYC? If so, it's not too cold if your are dressed correctly. I lived there for 30 years and took a walk every day. Some times I needed long underwear, two pairs of socks, gloves, hat, and several layers of clothing. Other times not.

The main problem in NYC during the winter snow (which can be deep) and the large puddles that accumulate at street corners when snow melts. Under these conditions I always wore overshoes of (which, I'm happy to report, I do not need here in Seattle).

While it is hard to predict weather, it is almost unheard of to have snow in mid December. It usually doesn't get very cold until around New Year's. I can't recall the last white Christmas. Your best bet is to have layers to wear. You probably won't need a hat, scarf and gloves, but you're safe if you bring them. Last winter was pretty mild - perhaps thanks to global warming.

Great links McLaurie.The food walking tours look really good, and may do one of them when we're there in November.

We had about 12" of snow I believe 4 or 5 Christmases ago. But it's true that more than light snow (an inch or two) is rare before Christmas.

But- you can get temps in the upper 40's or in the low 30's - and it can be damp and windy s well. You definitely need a winter coat, scarf, hat, gloves and waterproofed walking shoes or booties. Then, make sure you have a variety of sweaters and tops for layering.

(What feels only chilly in the few minutes from car to office or mall can get very cold when you're out in it for 2/3 hours at a time.)

Our winters have ben pretty mild the last few years. There was a snow storm a few Christmas' back 4 years or so, but that was the first "white" Christmas in a very long time. go here www.weatherunderground.com there is a "trip planner" icon which gives you the weather from years back and will give you an average so you know what to expect and what to pack. Right now we are having very high temps in the upper '80's....feels more like mid summer than autumn....go figure!
