Winter in South Florida?

South Florida weather is known to be warm most of the time especially from April to September. October, it starts to cool a little and and November is when we start to get some cold weather. The past few days, it's been dipping to the upper 40s and 50s and I like it. I'm a cold weather guy. I sleep without my shirt on even when the inside temperature is in the 60s but I do it under a blanket. I can't stand using the heater besides heating costs 10x more than cooling. This is the time of the year I just feel comfortable with the weather.
