In May to November, the average temperature is 26°C. A short-sleeved shirt and skirt or pants is also OK at this time. If you forget to take these things; it is quite cheap to buy them in the small market. If you are a diving-lover, it is strongly recommended to bring several changes of clothes with you, because once your clothes are washed, they won't dry quickly due to the humid weather. Typhoons occasionally occur during this season, so pack rain wear.
November to December, both the humidity and the temperature take a slightly fall, so long-sleeved shirts and sweaters are advised.
