The dry season runs from November to March. This is also the coldest time of year, when night-time temperatures require a good warm jacket.
The wet season follows the cool season from about May to October. From July to November, it's also typhoon season, when violent tropical storms can hit the coast. The rainy season is not an entirely bad time to visit. The rains usually only last an hour or two in the afternoon, leaving the rest of the time to explore with the sights pretty much to yourself.
