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.

July summary

After three months of unusually wet and cool weather, summer finally arrived in Washington in mid-July. A heat wave impacted most of the state from July 25 through 31, with plenty of daily highs recorded around the state. Most Washington locations had July average temperatures of 2-3 degrees above normal, despite the cool start of the month.

Read details, as well as a streamflow and drought update, examination of the frequency of hot temperatures in late summer, and a climate summary and outlook in the August issue of the State Climatologist Newsletter.
