YUMA, Ariz. (KYMA) - All of September, we had more days BELOW normal for the month. Now, Yuma didn’t break any new temperature records, but Yuma did have a pretty mild month overall. The coolest daytime high was Saturday, September 27, reaching only 83 degrees, which was 15 degrees BELOW normal.
We also had multiple days where Yuma had measurable rain, which is great for us. We definitely had an active end to the monsoon season.
