Monsoon 2022

Lightning hits behind Tumamoc Hill just after sunset as a several monsoon storms move through Tucson, Ariz., August 23, 2022. The storms produced localized flooding from heavy rains, especially in the southern portions of the area.

Despite storms across Tucson on Friday, the 2022 monsoon still fell short of the average.

The 2022 monsoon, which started on June 15, officially ended on Sept. 30 with Tucson receiving a total of 4.94 inches of rain. The Tucson International Airport, where the National Weather Service houses its official records, received 0.27 inches of rain on the season’s last day.

The average amount of rain seen during this time period is 5.69 inches, the NWS said.

While the airport saw a below average monsoon, other areas in Pima County saw a wetter season, the NWS said. Western Pima County saw an above average season while some areas in Eastern Pima County saw a normal amount of rainfall.Β

Even though this monsoon didn’t measure up to last year’s record-breaking season (which finished as the third-wettest on record, ending with 12.79 inches of rain), it is not as bad as other below average years. The NWS said the top 10 driest monsoons are all below 2.79 inches of rain.

And if you remember, 2020 was dreadful. It was the second-driest monsoon on record, tallying only 1.62 inches of rain the entire season.

For the next three months, Tucson is predicted to be drier and warmer than normal. For October, November and December, Tucson will likely see slightly below precipitation and above average temperatures, the NWS said.
