Weather conditions can utterly vary within the mountainous areas of northern Mexico, where winter seasons are very cold (late December to early March), usually freezing during the night time.

The fecund lands and thick jungles in the Yucatan Peninsula
and Southern Mexico
are characterised for their high temperatures
