Hotter than Fire

It's hotter than fire here in the Northeast, and I of course have been sending my hubby reminder texts: HYDRATE! Remember to drink water!  
I'm sure he's thrilled.
But the truth of the matter is that the weather effects a lot more than just his hydration level: it's been poppin' off in SoB, and they're busy as hell. People are uncomfortable and irritated, tempers flare, and the whole neighborhood is heated.
My question is this: does your Cop concur? How much of what happens on the job is actually weather-related? Extreme cold and extreme heat both seem to affect the human psyche in a way that we humans don't always understand...and the general public generally can't wrap their heads around how the weather has something to do with how my husband's day goes today.
