Warm - more than likely ... might even say hot. Windy - maybe, but shouldn't be important. Shorts - of course - every day. Light jacket ... basically it's possible for on board at night - maybe a light sweater around your shoulders for the cooler places on board (that's for a woman) - ashore maybe - particularly if it's a rainy day and then maybe something more like a rain poncho. You'll be way south of Florida ... check the weather channel for predictions.
I cruise the Emerald Princess, Eastern Caribbean on April 16, 2012
I always cruise in May. One is because that is when my anniversary is and the other is because of the weather. To me, May is perfect. No bad weather at all. Sometimes you will get alittle light raid but I have never seen a storm in my past 3 cruises. It is warm and sometimes down right hot. I have been known to wear a light sweater at night on deck but as I have said before, it is a beautiful time of year to cruise.
