I am coming to st martin aug 17-26th. I see that the weather forcast has said rain daily 30-60% recently. Is it like the Gulf of Mexico ..... it rains but only lasts a short period of time then it is sun and beautiful or is a down pit that lasts most of the day. We are taking a 7 night catermran from dreams. I just want to prepare myself if it will be wet most of the vacation
