Yeah you def notice a distinctive heaviness to the air once we go above 70. For me, it’s just the vibe of being able to walk around in light clothing with very little discomfort, unless you happen to be doing intense activities outside. I’m a little more biased since when I’m out I tend to sit out with a nice cold drink and soak up the sun or I’ll take a nice slow walk in the woods with the old doggie. I always try to think of this weather relative to what we typically have in say mid January and it’s a world of difference for enjoying time outdoors, especially if you’re a slow mover like myself.
