South Florida is so different from the rest of the United States that some people put their air conditioning on during Christmas. Most of November and December has been in the upper 70s and all around the 80s. That being said, as someone who works in an office at night and drives along the highway at 2:30AM, it can get chilly. A slight cold front is approaching. I’m not sure if the bikers I see on the expressway have heated motorcycle clothing or not. They probably do not, which may explain why they are speeding so fast at night.
