Weather tracker: Mexico swelters under season’s first heatwave

Anticyclonic conditions have allowed temperatures to reach 35-45C across much of the country

Mexico has been undergoing its first heatwave of the season. The heatwave started on Sunday 14 April, when Mexico City saw a new date record with a high of 32.9C, surpassing the previous record of 32C from 1998.

Anticyclonic conditions over the region have been responsible for this heatwave by inhibiting cloud formation, allowing temperatures to rise significantly. These conditions persisted through much of last week, allowing temperatures to reach 35-45C across much of the country.
