Well, it all depends and not in my opinion a straight yes or no question. I wouldn't say even March is too
early, just the earlier you head
north the higher the odds of running into a late season low.
It's all about low pressure systems coming in from Canada
, the strength of the system, the jet stream steering
currents, etc. Low pressure systems can happen any time of the year but tend to be stronger, more frequent and push further south in the winter. Depending on the whims of the weather gods this weather pattern could start in Sept and go until May or June.
A few years back I rounded Hatteras the first of Oct and saw the worst weather of my life. We had waves wash over the top of the pilot house in a 90' trawler
. I've also seen these systems hit FL as late as June.
All comes down to watching the weather and playing the percentages. The earlier in the spring you head north the greater the chance of a norther. Go too late and you are getting into hurricane
season. On the other end of the season, the later you go the higher the odds of a norther but lower odds of a late season hurricane
