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.
After three months of unusually wet and cool weather, summer finally arrived in Washington in mid-July.

Most Washington locations had July average temperatures of 2-3 degrees above normal, despite the cool start of the month.
