Monterrey has a [[semi-arid climate]] ([[Köppen climate classification]] ''BSh''), not having enough precipitation for a [[humid subtropical climate]]. Being inland at a modest elevation, it is one of the warmest major cities in Mexico.<ref>{{cite web |url=http://weather.com/ |title=National and Local Weather Forecast, Hurricane, Radar and Report |publisher=Weather.com |access-date=April 17, 2011 |archive-url=https://web.archive.org/web/20140509161400/http://www.weather.com/ |archive-date=May 9, 2014 |url-status=live }}</ref> Summers are generally hot, spring and fall temperate, and winters mild, with temperatures rarely below freezing.<ref>{{cite web |url=http://www.weatherbase.com/weather/weather.php3?s=049367&refer= |title=Monterrey, Nuevo León Travel Weather Averages |publisher=Weatherbase |access-date=November 17, 2012 |archive-url=https://web.archive.org/web/20131229121744/http://www.weatherbase.com/weather/weather.php3?s=049367&refer= |archive-date=December 29, 2013 |url-status=live }}</ref> The average high in August is {{cvt|36|°C|°F}} and the average low is {{cvt|24|°C|°F}}. The average January high is {{cvt|22|°C|°F}} and the average low in January is {{cvt|10|°C|°F}}. Rainfall is scarce in winter, but more frequent during May through September.

Monterrey frequently experiences extreme weather changes; for example, it sometimes reaches {{cvt|30|°C|°F}} in January and February, the coldest months. The most extreme weather changes in summer occur with rainfall, which can reduce temperatures significantly, and the temporary absence of the ''northern winds'' in winter, which can lead to abnormally high temperatures. Seasons are not well defined; the warm season may start in February and may last until September. In April and May 2011 temperatures reached {{cvt|45|°C|°F}} or higher, causing fires and extreme heat. Snow is a very rare event, although an accumulation of {{cvt|20|in|cm|-1|abbr=in|order=flip}} in 8&nbsp;hours occurred in January 1967.<ref name="Winkler">{{cite journal |last=Winkler |first=William |title=The Weather and Circulation of January 1967 |journal=Monthly Weather Review |volume=95 |issue=4 |pages=227–233 |url=http://docs.lib.noaa.gov/rescue/mwr/095/mwr-095-04-0227.pdf |access-date=January 29, 2013 |year=1967 |doi=10.1175/1520-0493(1967)095<0227:ammwuh>2.3.co;2 |bibcode=1967MWRv...95..227W |archive-url=https://web.archive.org/web/20130522204642/http://docs.lib.noaa.gov/rescue/mwr/095/mwr-095-04-0227.pdf |archive-date=May 22, 2013 |url-status=live |doi-access=free }}</ref> The most recent snowfall was in February 2021. Sleet and ice events occurred in January 2007, December 2009, January and February 2010, and February 2011,<ref>{{YouTube|23qSWFb-aE4|Monterrey Nevada Febrero 2011 }}</ref> caused by temperatures around {{cvt|-5|°C|°F}}.

From June 30 to July 2, 2010, Monterrey was hit by the worst natural disaster in the city's history when [[Hurricane Alex (2010)|Hurricane Alex]] delivered more than {{cvt|584|mm|in|0}} of rain in 72&nbsp;hours, with areas reaching up to {{cvt|1|m|in|0}} of rain during that same period, destroying homes, avenues, highways and infrastructure, and leaving up to 200,000 families without water for a week or more. The amount of water that fell was equivalent to the average precipitation for a year. This was about 3–4 times as much rain as [[Hurricane Gilbert]] produced in the city on September 15, 1988. The death toll of Hurricane Alex was estimated to be around 20.
