Climate Data Historical

The climate in Mexico varies, largely by altitude, with some areas experiencing desert-like conditions and others experiencing a more tropical climate. The northern part of the country experiences cooler temperatures and peak rainfall during the winter months. The southeast of the country experiences a tropical rainy climate that ranges from no dry season to a short dry season. El Nino events typically bring cool, wet conditions to northern Mexico (in winter), and La Nina bring warmer, drier conditions during this same period.


  • Mean annual temperature has increased by 0.6°C since 1960, at a rate of approximately 0.13°C per decade.
  • The rate of increase is most rapid in the dry seasons (March-May and December-February) at a rate of 0.18-0.2°C per decade and slower in the wet seasons (June-August and September-November).


  • Mean rainfall over Mexico does not show any consistent increase or decrease since 1960.
  • A particularly wet autumn in 2004 caused an apparent increasing trend in September-November.
