Phoenix, AZ – Arizona cities recorded a wetter-than-normal September this year, according to the U.S. National Weather Service. The monthly climate summary showed that Phoenix, Yuma, and El Centro all experienced above-average precipitation, with Phoenix leading the way at 1.69 inches over normal rainfall.
According to the National Weather Service Phoenix office, the city finished the month with an average high of 100.5°F and an average low of 79.8°F, placing its mean temperature 1 degree above normal. Yuma, meanwhile, recorded a slightly cooler September with a mean temperature 1.1 degrees below normal. El Centro followed a similar pattern to Phoenix, logging warmer-than-average nights that pushed its mean temperature up 0.3 degrees.
Rainfall totals in all three areas exceeded historical averages. Phoenix picked up 2.26 inches of rain in September, while Yuma collected just over an inch, and El Centro measured 0.42 inches. The increases marked a notably wetter month across southern Arizona and nearby California desert communities, regions that typically see limited rainfall in early fall.
For Phoenix residents, the rain helped cool some days but also added extra humidity. Yuma residents saw a split: cooler daytime highs but warmer nighttime lows. El Centro experienced the sharpest nighttime jump, with average lows nearly 4 degrees warmer than usual.
The September shift continues a year marked by varying climate swings across the Southwest, and forecasters are keeping a close eye on precipitation patterns heading into October.
