Statewide conditions

Updated April 9, 2021

As the state's lead agency for water supplies, we pay close attention to multiple data sources and monitor them closely. The Office of the Washington State Climatologist serves as a credible and expert source of climate and weather information for the state. Their monthly newsletter reviews the previous month’s data and provides an outlook for the coming weeks.

March summary

March temperatures were generally on the chilly side west of the Cascades and near normal to above normal in Eastern Washington, with few extremes. March was dry: Precipitation was below normal for both Eastern and Western Washington with records broken for lowest total precipitation or fewest wet days. This caused increasing drought conditions in some areas of Eastern Washington, but snowpack continues to be healthy throughout the state’s higher elevations. As of April, typically the peak of snowpack season, the snow water equivalent ranged from 95% of normal in the Lower Pend Oreille basin to 157% of normal in the Central Puget Sound area.
