2017 Phoenix & Yuma Climate Year in Review |
|
The year 2017 ended up being the all-time warmest year recorded in the history of central Arizona (Phoenix), as well as the warmest ever recorded for southwest Arizona (Yuma). In fact, the year will go down as one of the top 2 warmest for the state as a whole after all data are compiled. Records for Phoenix began in 1896, first taken in downtown and since moved to Sky Harbor airport in the 1950s. Records in Yuma began in 1878. Heat was obviously one of the biggest stories in 2017. Not only from an annual record setting average, but also periodically on a daily basis. In fact, Phoenix experienced its 4th hottest temperature ever recorded on Jun 20th. While extreme heat was certainly a major impact, the total number of 100 and 110 degree days in Phoenix and Yuma were not particularly unusual (ironically, both cities had exactly the same number of 100 & 110 degree days). The other predominant weather story in 2017 was the prolonged periods without rainfall. The first 3 months of the year began very optimistically, however Monsoon rainfall was very spotty and the last 4 months of the year turned exceptionally dry. In fact, the complete lack of rainfall in Phoenix exceeded 100 days by the beginning of December and became one of the longer rain-free streaks in the climate history of the city.
