We came back last Sunday from 2 weeks away and it never rained once. Hurricane season runs from June - November so you should be fine as long as you avoid this time. However if it does drizzle when you are away you may be thankful for it. Average temp was in the 40s when we went and by the end of the 2nd week the heat was killing us.
We went July n weather was stunning! Had couple hurricane days but was ready for break in humidity! I have to take school hols otherwise would go in may/June xx
