Iowa Weekly Weather Summary
Oct. 13 – Oct. 19, 2025
DES MOINES, Iowa (Oct. 20, 2025) — Iowa Secretary of Agriculture Mike Naig commented on the Iowa Department of Agriculture and Land Stewardship’s weekly weather summary released today. Information from the Iowa Crop Progress and Condition Report, which is released weekly by the United States Department of Agriculture National Agricultural Statistics Service from April through November, was not available due to the federal government shutdown.
“With only light rain in parts of the state last week, the warm temperatures provided another wide window for farmers to continue steady harvest progress. Looking at the past five years of reported averages, Iowa farmers have harvested about 85 percent of soybeans and 60 percent of corn by this point in the season. Based on what I am hearing from farmers around the state, we are on pace this year and maybe even a little ahead of schedule,” said Secretary Naig. “While northern Iowa may see the first widespread freeze of the season this week, warmer temperatures with more chances of rain remain in the forecast through the end of October.”
