Hello, the weather is hard to forecast. Sometimes typhoon would come but sometimes not. But please take it easy, typhoon would not affect the weather for more than 3 days. I think it won't affect much to your visit. If possible, you can stay in one of the local hostels to be closer to the local life. You can also go to Jin Long Lu snack street, it is the best snack street in Haikou. Have a nice trip!

Typhoon will not effect the weather for a long time,maybe one day rainning. But at the meantime,it brings cool air. Not that hot just like autumn,feels great.

yeah.it will be the typhoon time then.but does no't mattter the typhoo is always very quickly passing away.for the sightseeing, peopel all know that most the attractions are in sanya city,not in haikou very much,for the foods, you'd better tast the four famous dishes on hainan:wenchang chicken,jiaji duck,hele crab. and dongshan mutton,very famous in China, You can have a try on hainan seafood. very fresh and local customs. have a great time there. i can be you guide if you like .hehe
