Climate
The municipality belongs to Type II Climate characterized by the absence of a dry season and very pronounced maximum rainfall from November to December. It is during these months that the Northeast monsoon season occurs and the tropical cyclones contribute to the increased rainfall in the area. In January and February, the effect of these air masses on rainfall is considerably radical. In addition to the north-east monsoon during the months of February and March, the trail winds traveling from East to West do not give significant increase of rainfall. Likely, the month of May is the transition period between the monsoon that is prevalent from June to September. During the south-west monsoon season, the linear system called the Intertropical Convergence Zone (ITZ), brings the largest amount of rainfall to the area. In October, which is the transitive period between the south-west and north-east monsoons, the tropical cyclone brings considerable amount of rain.
The rainfall distribution in the municipality is greatly influenced by the air streams, tropical cyclones, the Intertropical Convergence Zone, shorelines, easterly waves and other rainfall-causing weather patterns. The rainfall season occurs from June to December with high rainfall intensity of 285.06mm to 474.22m and less rainfall intensity of 245.30mm to 224.06m from January to the month May which at the same time is the onset of effective rainfall with 75% probability and it would terminate in February of the following year which consequently during this period the mountainous areas receive higher intensity of rainfall. But the trend of monthly rainfall is unimodal (having one peak) and the maximum rain period is from October to December. On the other hand, the monthly average rainfall varies from 125.86mm to 594.56mm with a mean annual rainfall of 298.54mm.
The winds are influenced by the monsoon and the Pacific Trade System with Northeast direction that occurs in November to February; Easterly winds during the months of March, April, May and October; Southwest winds in June to August; and Westerly winds in September.
The maximum temperature during the month of January reaches about 27.9°C while 31.8 °C in November. The minimum temperature from December to June reaches about 20.6 °C to 24.5 °C; and the average monthly temperature is recorded at 25.0 °C in January to 27.9 °C in June.
Relative humidity is indicative of the amount of water vapor present in the atmosphere. Humidity in the Philippines as in the municipality of San Jose is high because of the warm moist air streams flowing over the archipelago, the surrounding seas, rich vegetation and abundant rainfall. The lowest average relative humidity occurs in May with 85.9%; highest in February with 93.4%; and the annual average humidity is 90% which is higher than the regional and national average of 82%.
Typhoon and storm surges
The tropical cyclone is a climatic control that contributes largely to the rainfall from June to December. It was shown to usually cause maximum values of rainfall and winds as exemplified by the highest wind speed of 77 miles per second as recorded in Virac, Catanduanes areas during the height of Typhoon Sening in 1970.
The tropical cyclones are internationally classified with these depending on their maximum wind speed or peak wind velocities (V) as follows: Tropical Depression, V<33 knots (63 km/h) Tropical Storm, 33 knots < V < 47 k (87 km/h) Tropical Storm, 47 knots < u < 63 knots (116 km/h) Typhoon, u > 63 knots (116 km/h)
The cyclones affecting the Philippine islands originate from the Pacific Ocean East of the Islands between latitude 8 degrees North, 10 degrees South, traveling on a Westerly or Northwesterly course over the country. It has the highest sustained wind velocity of 6 knots in November to April and lowest sustained wind velocity of 4 knots in September. Note that the average cyclone that passes over mainland Bicol which include San Jose town is 3 cyclones for every 2 years.Research Study by PAGASA (1948-1982)
Topography The terrain of the municipality is characterized as level to gently rolling and sloping. About 91.96% is characterized as having a generally flat terrain with a slope 0-3% which is described to be level to nearly level. It practically covers the entire land area of the town except barangay Adiangao which is located along the mountain range of Caramoan Peninsula which has an undulating to rolling terrain with 8.04% portions of steep slopes.
The elevation of the municipality is roughly 92.55% low to very low with a mean elevation from 0–100 meters above sea level. Hence, low elevation is about 5.72% ranging from 100 to 300 meters above sea level as well as 1.73% with moderately high elevation ranging from 300 to 500 meters above sea level.
Geology The major part of the municipal area is composed of Alluvium River Terraces which is particularly described as fluvicatile lacustrine alluvium composed of unsorted loosely consolidated pebbles, gravel, silt, coral debris and clay that can be found in flooded plains, riverbanks, sand bars, beaches, and tidal flats. It is notable that river terraces along the Lagonoy River and its tributaries which include also the Rangas River that practically originating from the foot of the Mount Isarog account for about 90.69% or 4,264.9826 hectares of the total land area of the municipality while the rest is of igneous and metamorphic rock origin of which volcanoclast alluvial fans cover about 0.19% or 8.94 hectares. These are specifically found in barangays Catalotoan and Salogon. Note that volcanoclast is a thick and extensive pyroclastic material consists of ashes, cinder lapili, tuff agromerate and volcanic debris while alluvial fans consists only of worked pyroclastics.

On the other hand, barangay Adiangao is composed of igneous and metamorphic rocks classified as Basement Complex. It is characterized as highly fractured and folded complex consisting of quartzite, quartzatedspathit and mica schists that cover roughly 5.26% or 247.37 hectares. Meanwhile, the lower part of the place is composed of sedimentary rocks known as crystalline limestone which covers about 3.86% or 181.53 hectares. Crystalline limestone is an extensive transgressive rectal carbonated facies including wall preserved bushes of corals, megafossils and algae structure, detritae to fuffacious limestone showing well developed karst landforms or formation that can be found prevalent in the Caramoan Peninsula.
Landforms The many landforms found in the municipality have been the natural production of the different geographical pressures of the different structural land forms such as alluvial lowland, alluvial fans, sedimentary plateau or masses of residual slopes and thick sedimentary landscapes. Most of its territorial areas are best characterized by broad alluvial plans described as level to nearly level, and moderately well-drained terraces. The level to undulating plains are the product of paludal environment or deltaic plains which are usually being flooded during slight and heavy downpours.
On the other hand, Barangay Adiangao is characterized by Shale/Sandstone Hills (SSH) which is described to be undulating to rolling, slightly to moderately dissected, and moistly top-rounded hills, both are low and high relief. Likewise, steep slopes are dissected closely with each other particularly those with greater than 18o inclinations. Meanwhile, V-shaped valleys are noted to have been composed and dominated by sandstone. Likewise, landforms in barangays Dolo, Sabang, part of Minoro, Manzana and Tagas are noted to be flat with very poorly drained terrains and oftentimes affected by floods caused by high tides. The coastal plains are most commonly swarmed with mangroves, nipa plants, break rides, swales and tidal flats.
Major Types of Land Management Units The municipality is composed of 5 major types of Land Management Units (LMUs) which are classified into 2 forms, namely: Warm Lowland and Warm Cool Hillyland. They are enumerated and explained below.
Warm Lowland: Tidal Flats (LMU 02) is very deep, fine loamy dark grayish brown but sometimes coarse loamy grayish soil, medium acid to mildly alkaline reaction, low available P and CaMg but adequate with O.M., constant extractable KBSP and CEC; generally moderate fertility level, very low infiltration and moderate to slow permeability rate, submerged and very poorly drained. Beach Ridges and Swales (LMU 03) is shallow to moderately deep, very dark brown, coarse, and loamy underlain by sandy skeletal substratum; slightly acid to mutual moderate CaMg and CEC; available highly extractable K acid; BSP generally moderate fertility level; rapid to very rapid infiltration and rapid to moderate rapid permeability rate, and excessively drained. Estuarin Plain (LMU 04) is deep to very deep clay, predominantly very dark brown, yellowish brown, coarse, loamy underlain by sandy skeletal substratum; medium acid to neutral soil reaction; moderate exchangeable K, high O.M. content, available P, BSP and CEC; generally high fertility level; slow to very slow infiltration and rapid to moderately rapid permeability rate, and moderately well to poorly drained.
