Monterrey

Climate Characteristics of Monterrey

General Overview

Monterrey features a hot semi-arid climate. Due to its northern location and proximity to the desert, the weather here is much more extreme than in central Mexico. Summers are scorching and long, while winters are short and can bring sudden, extreme temperature drops due to cold air masses from the north.

Summer and Warm Months (May to September)

Summer in Monterrey is hot and often humid. Daytime temperatures regularly exceed 35°C (95°F) and can even reach 40°C (104°F) or more. Although it is the hot season, most annual rainfall occurs in late summer and autumn (August-September) as a result of intense thunderstorms or tropical storm influences from the Gulf.

Winter Season (December to February)

Winter in Monterrey is generally mild but completely unpredictable. One day can be sunny and pleasant (20°C/68°F), and the next, temperatures can plunge near 0°C (32°F) due to cold fronts known as "Nortes". Snow is an extremely rare event in the city itself but is common in the surrounding mountains.

Spring Season (March and April)

Spring in Monterrey is very short and quickly turns hot. This is a time of strong winds and dust, but also the period when nature around the city is relatively green before the intense heat of July.
