Summer is getting warmer in Washington State

Summer (June-July-August) temperatures in Washington have risen at a rate of 0.21 F per decade since 1930, and 0.37 F per decade since 1950.  Seven of the ten warmest summers on record since Washington began keeping track in 1895 occurred after 1985.1 The warming is consistent with broader patterns of average temperature increase in the American West that have been attributed, at least in part, to human-induced climate change.
