Autumn is a wonderful time to get married… and makes for GORGEOUS Photos.
But as you’ve discovered it isn’t the best time for a Southern / Caribbean Honeymoon.
The Atlantic Hurricane Season runs from June 1st to November 30th… and as @raziel1687: has stated we are talking weather here, and as such weather is unpredictable… and Hurricanes are no different. One year there can be tons of activity, another year very little.
Example… 2012 had 19 Storms, 10 of them were Hurricanes, and 2 of them were Cat 3s or higher
This year 2013, so far there have been 12 Storms, 2 Hurricanes, and 0 of them at Cat 3 or higher
Now how to plan…
Well personally, I won’t head off to the northern or middle Caribbean (Greater or Lesser Antilles) during Hurricane Season… I just don’t want to risk my time, or hard earned vacation dollars on a potential natural disaster in a 2nd or 3rd world country, feeling trapped and unable to leave etc. No thank you
I am not quite so concerned about the Southern USA during Hurricane Season (and I admit a lot of that has to do with the fact that it is a first world country)… AND the fact that you can usually make far more refundable arrangements here on the mainland than you can in another country.
Ask about Hurricane Guarantees or Hurricane Insurance when you book your holiday.
All that said, come August, September, October… I am far more likely to plan my vacation elsewhere… as raziel1687: stated… North, Central, West… are all good choices (New England is particularly incredible in September… and although it too can be effected by a “passing” Atlantic Hurricane chances are lower)
IF you absolutely must go to the Caribbean, I agree with @Daizy914: look at the Netherlands ABC Islands (Aruba – Bonaire – Curacao) as they are off of Venezula and south of the usual path for Hurricanes.
Hope this helps,
