Like most of the Texas Panhandle, Amarillo has a temperate [[semi-arid]] climate ([[Köppen climate classification]] ''BSk'').<ref>Depending on the climatologist's threshold, ''BSk'' if based upon the annual mean temperature (<{{convert|18.0|°C|1|disp=or}}), ''BSh'' if based upon the daily average temperature in the coldest month (≥{{convert|0|°C|disp=or}}).</ref> Both the city and most of the county as a whole lie in [[Hardiness zone|USDA Plant Hardiness Zone]] 7a.<ref>{{cite web|title=USDA Plant Hardiness Zone Map|url=http://planthardiness.ars.usda.gov/PHZMWeb/#|url-status=dead|archive-url=https://web.archive.org/web/20140227032333/http://planthardiness.ars.usda.gov/PHZMWeb/|archive-date=February 27, 2014|access-date=February 24, 2014|publisher=Agricultural Research Center, PRISM Climate Group Oregon State University}}</ref> Amarillo is characterized by a winter season featuring large [[diurnal temperature variation]], great day-to-day variability, possible sudden and/or severe Arctic air outbreaks (in Texas, called "blue northers"), possible [[blizzard]]s and hot summers with generally low humidity. The average annual precipitation is {{convert|20.4|in|mm|disp=or}}. Much of Amarillo's precipitation falls during heavy convective showers and thunderstorms during the late spring and summer months.

According to 'Cities Ranked and Rated' (Bert Sperling and Peter Sander), Amarillo averages 48 days per year during which thunder and lightning is reported. This is above the national average. These storms can be severe: Amarillo and the Texas Panhandle are situated in the western portion of "[[Tornado Alley]]" and are prone to severe weather events, occurring primarily between April and July. Severe thunderstorms can produce damaging straight-line winds, large hail, tornadoes, and flash flooding. Amarillo is no stranger to devastating tornadoes. Tornadoes have occurred in and around the city in 1968, 1970, 1982, 1986, 2001, 2007, and most recently in 2013, 2015 and 2016. The strongest tornado to ever hit Amarillo was a deadly F4 tornado that struck the city in the night time hours of May 15, 1949. Amarillo suffered a direct hit, causing catastrophic damage and loss of life in Amarillo's most densely populated areas. The tornado devastated the south and east sides of the city, killing 7 people, and injuring more than 80 others. The monthly daily average temperature ranges from {{convert|38.6|°F|1}} in January to {{convert|79.6|°F|1}} in July. Sunny weather prevails year-round, with nearly 3300 hours of bright sunshine annually. The [[National Weather Service Amarillo, Texas|National Weather Service in Amarillo]] forecasts and provides climatic data for the city.

Extreme temperatures range from {{convert|−16|°F|1}} on [[Great Blizzard of 1899|February 12, 1899]] to {{convert|111|°F|1}} on June 26, 2011, but lows do not typically dip to {{convert|0|°F|1|disp=or}} in most years, while highs above {{convert|100|°F|C|1|disp=or}} are seen on 4.7 days on average. On average, there are 5.9 days of lows at or below {{convert|10|°F|1|disp=or}}, 8.8 days where the temperature fails to rise above freezing, and 61 days of {{convert|90|°F|1}}+ highs. Unlike in the Rio Grande Valley or eastern portions of Texas, days where the low does not fall below {{convert|70|°F|1|disp=or}} are relatively rare, due to the aridity and elevation. Blizzards occur occasionally, but snowfall is typically light, averaging nearly {{convert|18|in|cm|0|disp=or}} seasonally and the median figure is near {{convert|10|in|cm|0|disp=or}}.<ref>{{cite news |author=Doyle, Thomas |title=Experts say tornado season nears |date=March 29, 2001 |work=Amarillo Globe-News |url=http://www.amarillo.com/stories/032901/new_tornadao.shtml |access-date= January 26, 2007}}</ref> Amarillo is also recorded as the windiest city in the U.S. by the Weather Channel.<ref>{{cite web |url= http://www.weather.com/tv/tvshows/americas-morning-headquarters/10-windiest-large-cities-america-20140408?pageno=10 |title= America's Windiest Cities |year= 2014 |publisher= weather.com |access-date= April 16, 2014 |archive-date= April 15, 2014 |archive-url= https://web.archive.org/web/20140415190715/http://www.weather.com/tv/tvshows/americas-morning-headquarters/10-windiest-large-cities-america-20140408?pageno=10 |url-status= dead }}</ref>
