What is CIMIS?

The California Irrigation Management Information System (CIMIS) is a repository of climatological data collected at more than 100 computerized weather stations located throughout California. CIMIS helps agricultural growers and turf managers administering parks, golf courses and other landscapes to develop water budgets for determining when to irrigate and how much water to apply. Providing information for improving water and energy management through efficient irrigation practices is the primary use of the CIMIS system. CIMIS was developed by the California Department of Water Resources and the University of California at Davis. Operational since 1982, it has recently been redesigned to use the latest database technology. Access is now possible with high-speed modems as well as through the Internet. Access to CIMIS is free and the system operates 24 hours a day, every day of the year except during maintenance hours.
