This graph says so much more than I ever could. Every Summer since 2013, even the "cooler ones" like 2016 and 2019, are putting up top-tier 80F high counts. Almost effortlessly. 2015 broke new ground in that we spent *most* days hitting 80F. That's fairly outside climo. Pretty weird for Seattle.
Hyerbole? A bit, yeah. But the truth is dramatic enough.
