In terms of comparisons, it’s true that Canton is Minnesota cold. Looking at some of the colder Northeastern schools on this thread, SLU is 3 degrees (F) colder than Colby, 3.7 degrees colder than Middlebury, 3.8 degrees colder than Bates, and 3.9 degrees colder than Bowdoin. It’s a matter of perspective, however, as to whether differences within this range would be important.
