I am typing this form a coffee shop. Right now the (actual) temperature outside is -25 C (-13 F). I walked 20 minutes to get here, and I will walk 20 minutes to get back home. So far this winter, we have had 16 calendar dates for which the (actual) temperature has been -20 C (-4 F) or colder, and temperatures of -28 C (-18.4 F), -26 C (-14.8 F), -29 C (-20.2 F), and -24 C (-11.2 F) are forecast for the next four nights.
One morning, my 10-year-old daughter and I walked 30 minutes to her school when the temperature was -26 C (-14.8 F). Last Sunday afternoon it was -16 C (3.2 F), so my daughter and I decided that it was warm enough to go sledding for an hour. The hill was quite busy, so quite a few other people here had the same idea.
