Winters in Manitoba are very cold. So cold, in fact that I avoid leaving my house as much as possible. This is especially true in January and February, two months during which -35 / -40°C (with the wind) are a common occurrence.
(The wind chill can actually lower temperatures to -50°C!)
When March shows up, "warmth" follows suit. It starts feeling like spring and we don't need to dress like the Michelin Man anymore. ;-)
My photo sessions for the year will usually start around that month. If you are a nature photographer, it is a great time to take your camera out. Snow and ice create beautiful views.
Here is an example below. I took this photo almost three years ago, during one of my first outings of the season...
