The Wisconsin State Climatology Office is affiliated with the Department of Atmospheric and Oceanic Sciences
at the University of Wisconsin-Madison.
Our
mission
is to:
- provide evidence of climate change & variability through graphical data analyses,
- provide climate information to Wisconsin residents, climate scientists and government agencies,
- develop "value-added" products for users and impact applications,
- conduct applied climate research.
Detailed annual summaries are found on the AASC web site.
This office is a partner with Midwestern Regional Climate Center in providing climate services to the public.
Collaborations with
Wisconsin Initiative on Climate
Change Impacts (WICCI)
research on climate impacts are now underway.
If you would like assistance finding the climate data you want, visit our Guide to Wisconsin Weather and Climate Data.
The office staff is currently an all-volunteer operation.
Short initial inquiries for data or staff assistance staff are free. More substantial efforts are covered by our Service Charge statement.

2021: A LENGTHY, VERY DRY SPRING & SUMMER
Persistent drought in southern Wisconsin dominated southern counties in Wisconsin throughout the entire growing season. Northwestern counties also intensified moisture deficits in late summer. In early September, the Wisconsin map for the U.S. Drought Monitor showed a total of 21% of the state experiencing moderate or severe drought conditions.
Following below normal statewide precipitation beginning in Autumn 2020, southern Wisconsin experienced Spring 2021 deficits of 4-7 inches. Conditions worsened during the entire summer, with final growing season deficits of 5-10 inches common.Topsoil and subsoil moisture shortages ranged from about 22% in the Southwest to 70% in the Southeast.
2019: WETTEST YEAR ON RECORD ACROSS WISCONSIN
The statewide average precipitation for the 2019 calendar year was 44.55 inches, breaking the previous annual statewide record of 41.28 inches (for a 12-month period) set in 1938. The statewide precipitation records extend back to 1895.
