2024 Climate Year in Review for Phoenix, Yuma, and El Centro

The year 2024 ended up being the warmest year recorded in the history of Phoenix, Arizona. Extensive missing temperature data at Yuma and El Centro precludes any definitive ranking this year. Rainfall in Phoenix for the year was much below average, and ranked as the 23rd driest. Equipment failures at Yuma failed to record events required to make an annual total. Records for Phoenix began in 1896, first taken in downtown and since moved to Sky Harbor airport in the 1950s.

An El Nino pattern was prevalent early in 2024, though conditions gradually turned neutral during the spring. Not all El Nino's produce wet weather in the Southwest, however drier weather earlier in the winter became wetter towards the beginning of spring. This wet period was much needed after a hot, dry 2023 monsoon. With this pattern of periodic storm systems early in 2024, temperatures oscillated around the monthly averages through April.

The late spring and beginning of the 2024 summer monsoon marked a distinct change in the overall pattern as the cooler and wetter early spring turned dry and hot. Moisture intrusions typical for the monsoon and supportive of thunderstorm development were slow to arrive into the region, and prolonged periods of dry weather persisted through the summer. As a result, the summer months repeatedly ranked in the top 5 hottest months on record, and the summer as a whole ranked as the hottest on record for the entire region.

Occasional thunderstorm days were few and far between for much of the area, and the recording station at Phoenix Sky Harbor airport reported its 7th driest monsoon on record at only 0.74". However, there were a few notable events during the monsoon including a series of microbursts around the Phoenix metro on July 24th that caused a warehouse to collapse. On August 6th, there was a larger downburst resulting in wind damage around the McCormick ranch area. And on August 22nd, a large dust storm with isolated wind damage moved through the Phoenix metro.

The hot, dry weather did not come to an end with the cessation of the monsoon. In fact, an unprecedented string of exceptionally hot days persisted well into October before the typical cooler autumn weather finally arrived in November. This spell of climatologically normal temperatures were fairly short-lived as abnormally warm weather returned in December with the arrival of a weak La Nina pattern. All told, 2024 will go down as one of the hottest years on record for the entire Southwest region.
