2018 Weather Summary

In 2018, Iowa received 45 inches of rainfall — nearly 10 inches more than normal.
That puts 2018 second only to 1993 for average statewide precipitation, according to the year-end Water Summary Update from the DNR.

While there was some dryness in the southwestern portion of the state, 27 northern Iowa counties marked their wettest year on record. Streamflow was above normal for most of the year, while shallow groundwater levels recovered from low levels in southern Iowa to become normal to above normal for the entire state.

DNR coordinator of hydrology resources Tim Hall says the entire state is in pretty good shape for groundwater going into the normally dry months of winter.

Temperatures were typical of Iowa weather in 2018 — all over the map. April was the coldest on record. May was the third warmest, and this June was the 10th warmest. November was six-point-four degrees below average and December was five-point-one degrees above average.
