The weather in Florida is always random and unpredictable. Thankfully, there are covers over the walkways, but if you are parked somewhere far away, then there isn't cover for that area. Some days are rainy, some sunny, and some are freezing!
The weather really never makes a difference in the campus experience. The University has great transportation to and from campus, and when it's raining, most of the buildings protect the students well as they walk in between classes.
