Already posted the stats for how different mid May to mid June was at SEA and OLM compared to 2015 (precip included). Obviously results may vary by location...
Grass isn't dying when they change color. It's just going dormant giving it that color and stopping it from growing. The same grass turns back green once fall arrives.
I guess something about your place prevents dormant grass. Most of the Puget Sound lowlands usually browns out.
Shade, certain types of soil, and wetter/humid microclimates can help retain the green.
