Manila is a humid tropical city with two climates: hot and wet. The dry summer season runs late December-May until the rainy season takes over in June. The best time of the year to visit Manila would be during the moderate time (September-November).
The Philippines lies in the middle of a typhoon belt, experiencing an average of 20 major storms annually. This leads to unpredictable weather patterns June-September, when the city can experience flooding. Carry an umbrella at all times.
