Misty,
We've cruised during the last couple of weeks in Aug and during the first two weeks of Sept. Thus far, we've been lucky (knock on wood...) and we've had very good weather, BUT it is the beginning of hurricane season, so keep that in mind.
Also, the Captain will be monitoring the weather and if there is a storm, he may change the route to avoid it.
Other posters may have additional advice.
Have fun!!
Ginny
