Nuevo Leon Weather Radar

Nuevo Leon climate

Nuevo Leon has a semi-arid to subtropical climate with extremely hot summers and mild to cool winters. Monterrey, the state capital and Mexico's third-largest city, regularly sees summer temperatures exceeding 40°C in the urban heat island, making it one of the hottest major cities in the country.

The Sierra Madre Oriental mountain range creates dramatic weather contrasts, with the eastern slopes receiving significantly more rainfall than the dry western plains. Monterrey averages about 600mm of annual rainfall, but tropical systems can dump that amount in just a few days, causing catastrophic flooding in the city's river channels.

Hurricane Alex in 2010 devastated Monterrey with unprecedented flooding, permanently reshaping the city's relationship with weather preparedness. Winter cold fronts bring occasional freezing temperatures and rare ice storms to the metropolitan area, while the northern plains experience more extreme cold snaps that can drop temperatures below -10°C.
