The following table lists records of extreme temperature in territories of North America, which here includes Central America and the Caribbean. The elevation in metres above sea level of locations reporting record minimum temperatures is given where relevant.
^†ʘ Record observed in an area with a permanent resident population. Unless otherwise stated, this will be the case.
^†O Territory or location has no permanent resident population.
^†50 Record in the last 50 years; only given if the all-time record occurred more than 50 years ago.
