ITCZ Season
Season starts when a wide area of tropical rains occur between the South China Sea and the Mariana Islands. The peak of the season occurs when the ITCZ is more active, bringing heavy rains from Philippines to Guam. Signs of peak is also when several typhoons start to form within that area. Season ends when ITCZ rapidly dissipates, from a large strong typhoon.

Northeastern monsoon season
Season starts when the Southwest monsoon season ends and when meteorologists in the Philippines or even in the Ryukyu Islands record temperatures lowering. Its peak is when the temperature is at its lowest. Season ends just before the ITCZ season starts.

Tropical cyclone season
This is unofficial by some agencies and for me (Typhoon2013). But season starts when storms develop within the edge of the ITCZ and Southwest monsoon. Peak is between September and October, when several depressions start to form in a month and more than 2 typhoons reach their peak above 116mph in a month. Season ends when the last typhoon (its peak between 90 and >143mph) dissipates.
