My FH and are planning on honeymooning a few days after our wedding. Maybe St Lucia/St. Thomas. Any recs are very needed and highly appreciated!

My husband and I want to honeymoon on a beach. How’s the weather like in St. Lucia end of July beginning of August? Where do you recommend we go. Just looking to go for five days somewhere warm to relax and also maybe do an activity or two get a nice tan and spend time together. July 29- August 4th.
