Introduction
(satellite image of the map of Brgy. San Isidro Cabuyao)
Barangay San Isidro is one of the 18 urbanized[1] barangays, comprising the city of Cabuyao in
the province of Laguna, Philippines. It is located around three kilometers from Cabuyao City proper,
along the national highway. According to the 2010 Census,[2] it has a population of 18,145 (having
increased from 15,495 in Census 2007[3]), making it the 5th largest barangay in Cabuyao by
population.
Theres no updated data regarding the population of San Isidro so the researcher get the increase
percentage of the population from 2007 to 2010 which is 17.1%and assumed that the current
population of 2020 will be 26,095.
The barangay got its name from its patron saint, San Isidro Labrador.
San Isidro is situated at approximately 14.2432, 121.1375, in the island of Luzon. Elevation at these
coordinates is estimated at 20.9 meters or 68.6 feet above mean sea level.

The City of Cabuyao has a total land area of 4,330 hectares and is politically subdivided into
18barangays. Barangays Uno, Dos and Tres located at the northern portion of the city serves as the
Poblacion. Table 2.1 summarizes the corresponding land area of the component barangays of the city.
Cabuyao is located 42 kilometres (26 mi) southeast of Metro Manila, at the western portion of Laguna. It
is bordered by the Laguna de Bay, the country's largest lake, to the north (N), Calamba City to the east
(E) with Barangays Uwisan (NE), Banlic & San Cristobal (E) and Mapagong & Canlubang (SE), some
portion of Silang, Cavite (Barangay Puting Kahoy) to the south (S) and by the Santa Rosa City to the west
(W) with the Barangays Malitlit (SW), Dita (W) and Caingin (NW) respectively. Cabuyao is 45 kilometres
(28 mi) away from Santa Cruz, the provincial capital, and 8 kilometres (5.0 mi) from the city center of
Calamba City, the chartered city and regional center of Calabarzon region.
The only lake found in Cabuyao is Laguna de Bay. Barangays situated along the lake are Bigaa, Butong,
Marinig, Gulod, Baclaran and Mamatid. Types of Fish found in the lake are kanduli, biya, talapia,
ayungin, hito, karpa, mamale, bangus, dalag, papalo, kakasuhet and dulong.[20] The Cabuyao Fishing
Port can be found on Barangay Marinig where many Cabuyeños and Cabuyeñas take zumba every
Saturday and Sunday as the sun rises.
Based on the Hydrologic Atlas of Laguna de Bay 2012 jointly developed by the Laguna Lake Development
Authority (LLDA) and Word Wide Fund-Philippines, the Bureau of Soils and WaterManagement (BSWM)
indicated four textural grades or soil types within Cabuyao City.Loam Type can be found in the upland
and southwestern portion of the city. This soil type also covers the soils of the plains where urban
barangays and agricultural areas are concentrated.Agricultural areas are also dominated by the Sandy
Loam Type. The Loam and Sandy Loam types areal so located along riverbanks, shorelines and on the
westernmost tip of the city, near the Tagaytay-Cabuyao boundary. On the other hand, Clay Loam covers
the western and slightly elevated portion ofthe city while Clay Type can be found at the eastern part of
the city, proximate to the shores of Laguna de Bay. These soil types are said to be generally suitable for
agricultural use, specifically for paddy rice, tree crops and diversified crops. See Map 2.4 for the Soil
Map.
Hydrologic
The hydrologic features of Cabuyao comprise 25% of the Santa Rosa Watershed, one of the 24
riverbasins draining to the Laguna de Bay. The streams draining the Santa Rosa river basin can be
grouped into three sets, all of which exhibit a sub-parallel pattern. The northern set originates from
theplateau section of the basin, deeply bisecting the slopes and extending towards the east in the area
of Sta. Rosa and Biñan. The central and southern set originates from the base of the dissected slopes
and drains to certain sections of Sta. Rosa City and the City of Cabuyao
For rivers, Cabuyao has the following:
Cabuyao River – Between the boundary of Santa Rosa and Cabuyao.
Marinig River – Between the boundary of Barangays Bigaa and Marinig. The river was connected from
Niugan-Sala river and the river flows directed to the Laguna de Bay
Niugan-Sala River – The river flows along the boundary of Barangays Niugan and Sala.
Tiway-Tiway River – The most famous river of the town. The river flows directed to the Laguna de Bay.
San Cristobal River – Between the boundary of Calamba and Cabuyao.
The ricefields/ricelands in Cabuyao are found in Barangay Bigaa, Butong, Marinig, Gulod, Baclaran,
Mamatid, San Isidro, Pulo, Banay-Banay, Niugan and Sala. As of year 2004,[22] the total area of riceland
is 940.56 hectares (9.4056 in square kilometers) and 468 farmers as per data of the City Agriculture
Office.
Laguna Water sources its supply from the ground water and Matang Tubig Spring. The company also
manages and operates the Laguna Well Field, one of the largest centralized water distribution system in
Laguna, which has the capacity to supply 100 million liters of water per day.
The demand for water supply of Laguna Water customers in Biñan, Cabuyao, and Sta. Rosa is at 150
million liters of water per day. With its current water sources, Laguna Water already has the capacity to
supply 200 million liters of water per day, hence, having a more than 35% buffer than the required
demand.

Precipitation
A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet
days in Cabuyao varies significantly throughout the year.
The wetter season lasts 7.3 months, from May 19 to December 29, with a greater than 38% chance of a

The drier season lasts 4.7 months, from December 29 to May 19. The smallest chance of a wet day is
16% on March 26.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of
the two. Based on this categorization, the most common form of precipitation throughout the year is
rain alone, with a peak probability of 61% on August 11.
The percentage of days in which various types of precipitation are observed, excluding trace quantities:
rain alone, snow alone, and mixed (both rain and snow fell in the same day).
Rainfall
To show variation within the months and not just the monthly totals, we show the rainfall accumulated
over a sliding 31-day period centered around each day of the year. Cabuyao experiences extreme
seasonal variation in monthly rainfall.

midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and
astronomical), and night are indicated by the color bands from yellow to gray.
Humidity
We base the humidity comfort level on the dew point, as it determines whether perspiration will
evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points
feel more humid. Unlike temperature, which typically varies significantly between night and day, dew
point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically
followed by a muggy night.
The perceived humidity level in Cabuyao, as measured by the percentage of time in which the humidity
comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year,
staying within 3% of 97% throughout.
The percentage of time spent at various humidity comfort levels, categorized by dew point.
Wind
This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters
above the ground. The wind experienced at any given location is highly dependent on local topography
and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Cabuyao experiences significant seasonal variation over the course of
the year.
The windier part of the year lasts for 5.1 months, from October 30 to April 1, with average wind speeds
of more than 7.2 miles per hour. The windiest day of the year is December 17, with an average hourly
wind speed of 9.1 miles per hour.
The calmer time of year lasts for 6.9 months, from April 1 to October 30. The calmest day of the year is

wide-area average surface temperature of that water.
The average water temperature experiences some seasonal variation over the course of the year.
The time of year with warmer water lasts for 2.7 months, from April 26 to July 18, with an average
temperature above 85°F. The day of the year with the warmest water is June 3, with an average

Best Time of Year to Visit
To characterize how pleasant the weather is in Cabuyao throughout the year, we compute two travel
scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based
on this score, the best time of year to visit Cabuyao for general outdoor tourist activities is from late
December to mid March, with a peak score in the second week of February.
The tourism score (filled area), and its constituents: the temperature score (red line), the cloud cover
score (blue line), and the precipitation score (green line).
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F.
Based on this score, the best time of year to visit Cabuyao for hot-weather activities is from early
January to early April, with a peak score in the first week of March.
The beach/pool score (filled area), and its constituents: the temperature score (red line), the cloud cover
score (blue line), and the precipitation score (green line).
Methodology
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016),
independent scores are computed for perceived temperature, cloud cover, and total precipitation.
Those scores are combined into a single hourly composite score, which is then aggregated into days,
averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for
fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in
question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of
precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F,
to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for
75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
Growing Season
Definitions of the growing season vary throughout the world, but for the purposes of this report, we
define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the
calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
Temperatures in Cabuyao are sufficiently warm year round that it is not entirely meaningful to discuss
the growing season in these terms. We nevertheless include the chart below as an illustration of the
distribution of temperatures experienced throughout the year.
The percentage of time spent in various temperature bands. The black line is the percentage chance that
a given day is within the growing season.
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal
development, and defined as the integral of warmth above a base temperature, discarding any excess
above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average growing degree days accumulated over the course of the year, with 25th to 75th and 10th
to 90th percentile bands.
Solar Energy
This section discusses the total daily incident shortwave solar energy reaching the surface of the ground
over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the
Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave
radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences some seasonal variation over the course
of the year.
The brighter period of the year lasts for 2.2 months, from February 23 to April 30, with an average daily
incident shortwave energy per square meter above 6.2 kWh. The brightest day of the year is March 30,
with an average of 6.7 kWh.
The darker period of the year lasts for 6.5 months, from June 2 to December 18, with an average daily
incident shortwave energy per square meter below 4.5 kWh. The darkest day of the year is August 2,
with an average of 4.0 kWh.
The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th
to 75th and 10th to 90th percentile bands.
