I cruised last October, 2001.. Our temperatures were nice, but VERY rough seas. The islands were GREAT, but we missed St. Maarten, and went to San Juan instead,and Castawy Cay twice due to a bad tropical storm. Our seas were pretty rough most of the time,and for a few days, we had seas with 15-18 foot swells. And one day was so bad and rough, we stayed in our room most of the day. We went up to dinner and didn't stay, so we went back down to our room. I was very nervous that one day (Thursday). When my husband ventured out for a walk, he said people were throwing up EVERYWHERE, in the stairs, on the floors. I can't wait to try again, but in a different month.I'll never do an October cruise again. BUT, the temperatures were very nice I must say. If stormy seas don't scare you any, October is the month for you otherwise.
