There are three recognized seasons: Tag-init or Tag-araw (the hot season or summer from March to May), Tag-ulan (the rainy season from June to November), and Taglamig (the cold season from December to February).
The humid southwest monsoon (May-October) is known as "Habagat". The cool and dry winds of the northeast monsoon (November April) are called "Amihan".
These seasons can seriously get mixed up by the El Niño / La Niña effects. El Niño brings dry weather and even droughts. La Niña stands for rainy weather and floods.
