===Climate===
Provo's climate can be classified as either a [[hot-summer Mediterranean climate]] classification ([[Köppen climate classification|Köppen]]: ''Csa'') or as a [[semi-arid climate#Cold semi-arid climates|cool semi-arid climate]] (Köppen: ''BSk''). Overall, annual rainfall at the location of BYU is around {{convert|17.23|in|mm|-1|sp=us}}; however, the western part of the metropolitan area near Orem is substantially drier, receiving only around {{convert|13.5|in|mm|-1|sp=us}} of precipitation and consequently has a [[semi-arid climate#Cold semi-arid climates|cool semi-arid climate]] (Köppen: ''BSk'').<ref name = NOAA /> The wettest calendar year in Provo has been 1983 with {{convert|37.54|in|mm|1}} and the driest 2020 with {{convert|7.28|in|mm|1}}.<ref name = NOAA />
 
Winters are cold with substantial snowfall averaging {{convert|57.2|in|cm|sp=us}} and a record monthly total of {{convert|66.0|in|cm|sp=us}} in January 1918, during which the record snow cover of {{convert|34|in|cm}} was recorded on the 17th. Seasonal snowfall has ranged from {{convert|127.5|in|cm|sp=us}} in 1983–84 to {{convert|10.1|in|cm|sp=us}} in 2014–15. Very cold weather may occur when cold air from over the [[Continental Divide]] invades the region: although only four mornings fall to or below {{convert|0|F|C|1|disp=or}} during an average winter and this temperature was not reached at all between 1999 and 2006, during the very cold January 1917 (average temperature {{convert|14.9|F|C|1|disp=semicolon}}), seventeen mornings fell this cold.<ref name = NOAA /> By contrast, in several recent winters like 1994–95, 1995–96, 1999–2000, 2004–05, and 2005–06, averages have been above freezing every month.
 
Temperatures warm rapidly during the spring, with the first afternoon over {{convert|70|F|C|1}} on March 21, the last freeze expected on April 29, and the first temperature equal to or hotter than {{convert|90|F|C|1}} on May 30. Rainfall is not infrequent during the spring: over {{convert|5.10|in|mm|-1|sp=us}} was recorded in the Mays of 1995 and 2011, and a total of {{convert|12.29|in|mm|1}} fell during the four-month span of March to June 2005 – in contrast as little as {{convert|2.04|in|mm|1}} fell in the same months of 2012.<ref name = NOAA />
 
Being too far north to gain any influence from [[North American Monsoon|the monsoon]] except in rare cases like the {{convert|4.38|in|mm|1}} of rainfall of August 1983, Provo's summers are hot and dry, though relatively short – no maxima above {{convert|100|F|C|1}} have been recorded outside the range of June 7 to August 27. Monthly maxima average over {{convert|91|F|C|1}} in July and August, and precipitation averages under one inch per month with a two-month total in 2016 as low as {{convert|0.06|in|mm|1|sp=us}}. The hottest month on record is July 2003 with a mean of {{convert|81.8|F|C|1}}, and a mean maximum of {{convert|99.0|F|C|1}}. The hottest temperature on record is {{convert|108|F|C|1}} on July 13, 2002.<ref name = NOAA />
 
The fall season sees steady cooling and a transition to winter weather, with rare influences of rain systems from further south, as in the record wet month of September 1982, which saw {{convert|6.53|in|mm|1}} of total precipitation, including {{convert|4.15|in|mm|1}} over the last six days from a storm moving in from Arizona. The last maximum of {{convert|90|°F|°C|1}} can be expected around September 10, and the first morning below freezing on October 14.<ref name = NOAA />
