It's not 90 degrees and sunny here every day. In winter the temperature can dip below freezing, and sudden thunderstorms happen almost daily in summer. For the most part, the weather is fair, averaging in the low 50s in Jacksonville and low 60s in Cocoa Beach in winter. Summer temperatures hover around 90, but the humidity makes it seem far hotter. March and April are good months to visit, since the ocean is beginning to warm up and the beaches aren't yet packed.
