According to a Portland, Ore., weather blog by Bruce Sussman, June 2011 highs were 4 degrees below normal, while July 2011 highs averaged 3 degrees below normal. Throughout the entire summer season, Portland had highs of 90 or higher on 7 days in 2011, whereas the average number of 90-degree days for the city is 13. The first day where the high in Portland climbed to 90 degrees or higher was August 20, 2011, when the thermometer soared to 96 degrees.

"July into early August may be a warmer period, especially just east of the Cascades with brief hot periods," Pastelok said.
The interior Northwest will heat up during the middle to latter period of the summer as the large dome of high pressure shifts farther north and west across the Rockies.
