Seriously, I go to a heavier bag, add long johns, rain pants, mid boots rather than low tops, switch zip-off pants for soft shell, and add a mid layer like a Power Stretch hoodie. Think of a 45F steam bath.
In the Washington Cascades, it is "shoulder season" from March to October except for August and maybe a couple weeks of July. Barely August this year. Yesterday was a screaming high of 69F and a low of 48F; the whole "summer" has been like that. Indeed, my favorite wine is "I wanna go to Maui."
