Last time I was at Princess Cays was in early April, so it should be relatively the same as now... it was great! Wasnt HOT... was just right. Hopefully you will have a nice sunny day to enjoy this port. The rest of your western itinerary ports are actually a bit warmer than the bahamas. In April, we were never REAL hot, but plenty warm. I do remember Cozumel being HOT one time, but that was in Novemeber, not sure if thats the norm or not. Have fun!!
