Most people wait until warm weather before doing any outdoor caulking projects because they believe it's easier to work with caulk when it's not cold. They may also believe the myth that you can't do exterior caulking unless the temperature is at least 40° Fahrenheit.
In fact, siding companies will tell you that there are specific kinds of caulk you can use when the temperatures dip below freezing. There are a variety of caulk materials available, knowing which ones are appropriate for the job you're doing is essential to getting a good seal.

For outdoor use around windows and doors, avoid latex, which can contain filler ingredients and will freeze before it sets properly. It also can't be used below 40°F. Instead, look for a high quality rubber or solvent based thermo-plastic material that can be applied at temperatures as low as 20°F.
These cold weather versions are popular with siding companies because they cure over a period of several days and can successfully cure at temperatures as low as -20° and as high as 200°F, eliminating any worry about a change in the weather after you've caulked. The caulk itself should be at room temperature when you begin using it.
Siding companies stress the importance of always preparing the surface properly before you begin working. Make sure there isn't any ice, dirt or debris on the substrate and make sure it's dry. Applying caulk over a damp area or the smallest bit of ice or water will prevent a proper bond.
