Summer - is hot and humid, especially inland, which is not touched by cool coastal breezes. Tropical rain showers and the occasional typhoon are also possibilities - light clothes and an umbrella are recommended. Winter - It remains fairly dry up until late February/March, when it starts to drizzle almost constantly and waterproofs become a necessity. Warm clothes are a must during the cool months, especially when travelling in the hill areas. Although temperatures can drop unexpectedly between December and February, it can be a good time to explore the sights as days are cool and rainfall is limited. It is also a safer time to visit the hill tribe region avoiding mosquito related problems - although temperatures can fall to freezing in these elevated areas. Best time to visit: During winter when rainfall is minimal and temperatures are not too low.
