Technically speaking, there are two types of season in the Philippines but have two types of climates. As we are located in the tropical region, we only have two types of seasons namely the wet and dry season. Our country’s overall temperature only had a very little variation throughout the year but the amount of rainfall varies a lot on different months of the year. In average, the temperature is at 26.6 C whereas the average rainfall for the past 10 years is about 2030 mm per year. But the effect of the Global Warming, this average temperatures and rainfulis experienced in both extreme conditions.
Since our country is located near the equator, all land areas of the country receives a direct heat and sunlight from the sun, therefore having a warmer climate as compared to other countries at the northernmost or at the southernmost parts of the world. Another reason for a warm climate is the mountainous area of the Philippines blocking the moisture in the air on one side resulting to a warm air on the other side very dry and warm. On the other hand, areas on the mountain tops have a colder climate because as the warm air goes up, it expands and cools as it meets air with lower pressures. In general, the air is colder to about 2 degrees in higher altitude beginning at 300 meters above sea level.
Another reason of a warm climate is that our country is surrounded by bodies of water such as the Pacific Ocean in the east and the China Sea on the west. Asthe sun heats up the ocean water, winds carry the heat from it towards the land. As a result, the climate is not only warm but also becomes humid. In average, the humidity of the air in the Philippines is about 78%.
Compare to other countries, the Philippines has two unique wind systems – the northeast monsoon and the southwest monsoon. The northeast monsoon is commonly known as “hanging amihan”. The term “amihan” was derived from the word “amianan” which is an Ilocano word for north. While the southwest monsoon is commonly known as “hanging habagat”. The term “habagat” was derived from the word “abagat” which is a Visayan word for south. “hanging” or “hangin” is a Tagalog word for “air”.
Because we are surrounded by large bodies of water, we both experience wet and dry season. During the wet season, we receive heavy rainfall which occurs from June to September. Beginning the months of October to December, the amount of rainfall we receive is relatively decreased. And during the rest of the months (January to May) we experienced a dry (and very humid) season in the whole archipelago.
But because of climate change, our country is experiencing extremes of both climates. when it rains, the downpour is very heavy and flooding is experienced in many parts of the country. When its dry or hot, we experienced a very hot temperatures about the average within the summer season.
