We are planning to go to cruise Tortola, St Maarten, Antigua, Guadeloupe, Martinique, Grenada, St Lucia, St Vincent and Grenadines, Barbados, Trinidad and Tobago. We like snorkelling, and we can't choose the month for our trip, beginning of january or march? Is there any difference in water temperature in january and march? Will the water be warm enough for snorkelling?
Thank you.
