Living in a hurricane zone - we tend to not travel during the month of September as that seems to be the peak - at least for here in the Gulf of Mexico. Last year, we did a New England/Canada cruise in mid September and missed two port on the 7 day cruise due to weather conditions.
In the end , it is just a crap shoot and luck. WE have sailed around or behind or in front of hurricanes in the past so just give it a go and go with your plans whatever they might be.
