- Tip #1 - pack really, really light clothing. And I mean *light*, because Haikou is hot and humid, the combo no one wants. Sorta like Houston in the middle of summer, or Phoenix in the summer except much, much wetter. When you sweat, it *sticks to you.* Makes you want to take a shower two or three times a day. I recommend going to a sports/outdoors store and getting clothes there for the day. Or if you’re a guy, just go shirtless and put some sunscreen on. - Tip #2 - be careful in the streets. It’s not that there are criminals around, but that the drivers here are really, really dangerous. Those lane markers? People drive like they aren’t even there, including my own relatives, which makes being a passenger really really fun. And most of the streets here *do not have lights. *Most people jaywalk across streets, it’s easier that way. - Tip #3 - sunscreen is your friend. While it’s been cloudy/overcast/raining these past few days, when it’s sunny, it’s *sunny, *especially at the beach. - Tip #4 - want to go to the beach? Head to Sanya. Beaches in Haikou are pretty bad, and besides, no one goes to the beach in Haikou, as it is quite ugly compared to Sanya’s beaches. Take a tour bus there.
