You may not believe this but it can be checked out if you wish to do so. I recieved and email from a friend that returned to Canada on the 11th of December and when they hit the airport in Edmonton Alberta early Saturday morning it was -54 degrees F with the wind chill. The airport nearly closed down and the next day Edmonton was the coldes place on the planet.

Things are relative, I am sure that the week after when it was
-30 my freinds from Edmonton found it bitterly cold, just the same as the San Pedranos fine 66 degrees bitterly cold.
