Drought in the California–Nevada Region

Drought in California and Nevada is a common occurrence that can last for multiple years. The regional climate is characterized by a distinct dry season (approximately May to September) and wet season (approximately October to April) defined by a few large precipitation events, though additional peaks in precipitation can occur. Topography within the region creates a diverse set of climate conditions, from the snowy peaks of the Sierra Nevada Range to the Mojave Desert, to the mountains and valleys of the Basin and Range. Given the extreme variability, both spatially and temporally, efficiently using and effectively managing finite water resources is a high priority.

To support drought early warning capacity and resilience to drought events in both California and Nevada, NOAA’s National Integrated Drought Information System (NIDIS) launched the California-Nevada Drought Early Warning System (DEWS). The California-Nevada DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region prepare for and cope with drought

Reach out to Amanda Sheffield, the Regional Drought Coordinator for this region, for more information, or sign up for the California-Nevada DEWS newsletter.

California Current Conditions

A number of physical indicators are important for monitoring drought, such as precipitation & temperature, water supply (e.g., streamflow, reservoirs), and soil moisture. Learn more about monitoring drought.

Historical Drought Conditions in California

Drought is a normal climate pattern that has occurred in varying degrees of length, severity, and size throughout history. Below, you can look back at past drought conditions for California according to 3 historical drought indices. The U.S. Drought Monitor is a weekly map that shows the location and intensity of drought across the country since 2000. The Standardized Precipitation Index (SPI) is a monthly depiction of drought based on precipitation (with data going back to 1895). And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records, going back to the year 0 for some parts of the U.S. View more historical conditions.

U.S. Drought Monitor

The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.
