The final tallies are in, and state climatologist Justin Glisan says 2023 is going down as one of Iowa’s warmest and driest years in more than 150 years of record keeping. Glisan says when you average out the temperatures over 365 days, it’s rare for Iowa’s year-long average temperature to vary by even one-degree above or below the previous year, but that changed during 2023.
As 2023 concluded, he says it ended 182 consecutive weeks of at least D-1 moderate drought in some part of the state. That’s more than three-and-a-half years of continuous drought and some sections of the state have very dry conditions.
The only corner of the state that recorded above-average precipitation during 2023 was northwest Iowa, which saw between one and three inches more than the norm. However, he says the rest of the state was exceptionally dry.
After three consecutive La Nina winters, we’re now in an El Nino pattern, which Glisan says tends to bring the Midwest warmer temperatures in addition to wetter conditions.
