CLIMATE IN THE
PHILLIPINES
The Climate of the Philippines is tropical and maritime. It is
characterized by relatively high temperature, high
humidity and abundant rainfall. It is similar in many
respects to the climate of the countries of Central
America. Temperature, humidity, and rainfall, which are
discussed hereunder, are the most important elements of
the country's weather and climate.
3. 3
HUMIDITY
Humidity refers to the moisture content of the atmosphere. Due to high
temperature and the surrounding bodies of water, the Philippines has a
high relative humidity. The average monthly relative humidty varies
between 71 percent in March and 85 percent in September. The
combination of warm temperature and high relative and absolute
humidities give rise to high sensible temperature throughout the
archipelago. It is especially uncomfortable during March to May, when
temperature and humidity attain their maximum levels.
4. 4
TEMPERATURE
Based on the average of all weather stations in the Philippines, excluding Baguio, the mean annual temperature is 26.6o
C. The coolest months fall in January with a mean temperature of 25.5oC while the warmest month occurs in May with
a mean temperature of 28.3oC. Latitude is an insignificant factor in the variation of temperature while altitude shows
greater contrast in temperature. Thus, the mean annual temperature of Baguio with an elevation of 1,500 meters is
18.3oC. This makes the temperature of Baguio comparable with those in the temperate climate and because of this, it
is known as the summer capital of the Philippines.
The difference between the mean annual temperature of the southernmost station in Zamboanga and that of the
northermost station in Laoag is insignificant. In other words, there is essentially no difference in the mean annual
temperature of places in Luzon, Visayas or Mindanao measured at or near sea level.

TROPICAL RAINFOREST
The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation
that form three different layers. The top layer or canopy contains giant trees that grow to heights of 75 m (about
250 ft) or more. This layer of vegetation prevents much of the sunlight from reaching the ground. Thick, woody vines
are also found in the canopy. They climb trees in the canopy to reach for sunlight. The middle layer, or understory, is
made up of vines, smaller trees, ferns, and palms.
7. 7
TROPICAL MONSOON
Tropical monsoon climates have monthly mean temperatures above 18 °C (64
°F) in every month of the year and a dry season. Tropical monsoon climates is
the intermediate climate between the wet Af (or tropical wet climate) and the
drier Aw (or tropical savanna climate).
8. 8
HUMID SUBTROPICAL
A humid subtropical climate is a zone of climate characterized by hot and
humid summers, and cool to mild winters. These climates normally lie on the
southeast side of all continents (except Antarctica), generally between
latitudes 25° and 40° and are located poleward from adjacent tropical
climates. It is also known as warm temperate climate in some climate
classifications.
9. 9
OCEANIC
An oceanic climate (also known as a marine or maritime climate) is characterized
by cool summers and cool winters, with a narrow annual temperature range
and few extremes due to maritime influence. Oceanic climates can be found
between 35° and 60° north and south of the equator, primarily on the western
sides of continents and in isolated locations.
Oceanic climates have a monthly mean temperature below 22 °C (72 °F) in the
warmest month, and above 0 °C (32 °F) (or −3 °C (27 °F)) in the coldest month.
10. SEASONAL
FORECAST
A seasonal forecast provides
forecast information about the
general weather conditions at
seasonal timescales up to several
months ahead. Long range
predictions rely on predicting
components of the atmosphere and
the oceans which show variations
at large spatial and temporal scales.

17. REGIONAL
FORECAST
A regional forecast is like a weather
prediction for a specific area, such as
a city, state, or part of a country. It
tells you what the weather will be like
in that particular place, including
things like temperature, rain, and
sunshine, for a certain period, usually
a few days ahead. It helps people
plan for outdoor activities or know
what to expect in their local area.
