It's the end of hurricane season and usually quiet. That being said, there was a hurricane last November (2001) which made for rough seas and rainy weather for the beginning of the 7 night cruise. The four night cruise ended up in Charleston, SC for a night or two. So it does happen. The weather in the islands was great though - hot, sunny though there was a bit of rain in St. Thomas. Florida was cool and rainy when we left but warm and sunny when we returned.
