Those events also topped out with one day a piece at 90 and 91 like this year. This month will be much wetter, though!
Every June from 2015-17, and four out of five from 2015-2019, hit 92+ at SEA. Since 2019, only 2021 has.
Just another stat that highlights the ridiculous warmth/dryness that dominated spring to early summer during the 2015-19 stretch.
