43 degrees is cold when just about an hour prior it was about 75 degrees. 30 degrees difference is a lot and makes it feel even colder than it is...it's all relative. of course those on the east coast, Canada, or anywhere else that it snows and gets down to like 15 degrees or even x amount of degrees below zero won't find it cold, but if you lived here for a long time, grew up here, or even moved here you grow accustomed to the weather. spend enough time living here and eventually you'll find 43 degrees to be cold.
at least that is what I tell myself

LOL!
