In the summer we get ridiculous high amounts of humidity. That's how it is in the Northeast during the summer. I imagine it's a bit less humid in Clearwater. I'm sure it gets hot in the summer there, but not as humid.
Not humind in Clearwater, are you nuts?

I think our climate is a lot like yours - very long, cold, snowy and blizzardy winters and then within a week it's 80s-90s and humid. This past week it's been hotter here in west Michigan than southern Florida (southeastern Florida is my second home, so I keep their weather ticker next to my local one). It also gets pretty humid, especially July and August. Often the humidity creates a 10-15 degree difference in the heat index, so if it's 90 it feels like 105. Last summer our paint peeled, my mattress grew black mold, and my framed photos were destroyed by humidity. Unlike Florida, many if not most people here don't have or use air conditioning.
We have basements which generally stay a bit cooler on their own, so I let the animals down there. Plus they can lay on the cement and keep moving around to a cooler spot. Once Chop arrives I'll probably get her a kiddy pool if she enjoys water and save any jogging or hard exercise for after sundown.
