This year we made this cruise on March 8-15. We previously went the last week in February and the weather was nice both times. Once it was cool in Long Beach (cloudy) but as you head south the air becomes warmer. I would say both times the temperature was high 70's to low 80's. Very pleasant and we wore shorts and t-shirts for all of our excursions. So that's what I would bring along with comfortable shoes or sandals, sunglasses, sunscreen, and a hat. Our favorite excursions were: "Las Caletas Beach Hideway" in Puerto Vallarta; "Shopping beach and lunch" in Mazatlan; and "Land's end boat, beach and shopping" in Cabo San Lucas. In PV, you board a boat which takes you south along the coast to Las Caletas. There are free drinks on board and a very nice buffet lunch when you arrive. You then have several hours to lay on the beach, explore the area, go kayaking, or snorkeling (all included). There is some entertainment on the boat ride back but I won't spoil the surprise. Very Fun. In Mazatlan, you will take taxi's to the golden zone and watch a performance by the Paplanta flyers. It is an interesting look into some native culture followed by free time to shop. You end up at the Playa Mazatlan which is a beautiful hotel on the beach for a very nice lunch. There you can swim in the pool, go out on the beach, or just relax. When you're ready to to back to the ship, the taxi ride back is included. In Cabo, you go out on a boat ride past the arches, lover's beach and back. Then you board a motor coach to a beach resort for lunch on the beach. After that, you will be taken to an air conditioned mall to do some shopping. All of these excursions were very pleasant and relaxing.
