California Irrigation Management Information System (CIMIS)

The California Irrigation Management Information System (CIMIS) is a platform run by the Water Use Efficiency branch of the California Department of Water Resources (DWR). The CIMIS program provides public access to data collected by automated weather stations across the state, aiding in the efficient management of the state's water resources.

CIMIS data provides irrigators with a data-driven approach to irrigation scheduling based on real-time climatic data and crop type. CIMIS weather stations measure relative humidity, hours of daylight, measurable precipitation, and ambient air temperature to calculate an ETo, or a reference ET. To estimate the actual ET rate (ETc) of your crop, simply multiply the ETo provided by the nearest CIMIS station by your crop coefficient (Kc). Follow the link below to access the DWR CIMIS data:
