what to pack for western Caribbean cruise in December?

Warm...Most of my cruises have been in February, and I have never needed a jacket. However, depending on the speed of the ship as it goes from port to port, it may be breezy on deck. One lightweight jacket should be quite sufficient. One pair of casual slacks, and a bunch of shorts. Temps should be in the 80s for most of the time. Water temps should be between 79 - 83 degrees.

Pack for a hot climate with little chance of rain. Remember your sunscreen and apply it every time you go on shore. Take a sun hat and comfortable sandals for walking about. Make sure that you pack your bathing costume and a beach towel if you plan to spend time on the beach. You might want to consider snorkelling equipment, as there are some good opportunities. Otherwise, it is up to you what you wear. Most people wear casual clothes for wandering about the ship and going on shore, but there will probably be formal dinners on board when you will need your glad rags, so make sure that you check on this beforehand. You will probably enjoy the opportunity to go shopping on shore and even on board ship, where there are usually bargains on offer.

Lightest possible clothes like shorts, jeans and blouses for offshore as well as on the ship. You can bring a wrap and swim wear for the beach and the pool on deck. Formal wear for the Captain's ball as suggested earlier. Towels are available so don't bring any. Many people dress for dinner nightly. So nice slacks or dress will suffice. You can think of interchanging blouses to go with the slacks. Just pack light.

I've been to Antigua a few times in the winter and of course its warm there so khakis and polos worked fine with sandals

it may be December, but plan for summer weather, try to stay out of hte sun as the sun is closer in winter than summer, and bring the umbrella too.
