El Salvador is located in northern Central America, where it is both the smallest and most densely populated country. Its geographic landscape features two parallel mountain ranges that cross the country with a central plateau between them and a narrow coastal plain hugging the Pacific Ocean.

The Natural Landscape of El Salvador

Nestled in northern Central America, El Salvador is strategically positioned, sharing borders with Honduras to the northeast and Guatemala to the northwest. Its geographic location grants it access to the Pacific Ocean and the Gulf of Fonseca, stretching across approximately 307 kilometers (191 miles) of coastline. This unique positioning makes El Salvador the only country in Central America without a shoreline on the Caribbean Sea.

With a total land area of 21,041 square kilometers (8,124 square miles), El Salvador is the smallest country in Central America. Its compact size belies its remarkable diversity, with landscapes ranging from lush rainforests to towering volcanoes. Spanning 270 kilometers (168 miles) from west-northwest to east-southeast and 142 kilometers (88 miles) from north to south, El Salvador is also Central America's most densely populated country.

The Pan-American Highway, CA-1 or Carretera Panamericana, is the nation's main road, connecting El Salvador with its neighboring countries. Traversing the country from west to east, this vital transportation artery facilitates the movement of people and goods, playing a crucial role in El Salvador's economy and development.

El Salvador, though modest in size, harbors a surprising array of ecosystems and species, contributing to its unique biodiversity. While not in the spotlight like some larger neighbors, the country hosts a rich mosaic of life.

Ranked as the 70th most biodiverse nation globally by the Global Biodiversity Index, El Salvador showcases its environmental wealth with 495 bird species, 30 amphibian species, 588 fish species, 156 mammal species, 135 reptile species, and an impressive 2,911 species of vascular plants. These numbers underscore the ecological diversity tucked within the nation's boundaries.

Conservation

In El Salvador, conservation efforts are paramount to safeguard the country's limited natural resources and preserve its biodiversity. Despite its small size and high population density, El Salvador has embraced the responsibility of environmental stewardship, recognizing the intrinsic value of its ecosystems.

Challenges to conservation in this dynamic Central American nation are manifold. Urbanization, pollution stemming from industry and agriculture, over-exploitation of natural resources, and the growing impacts of climate change present formidable hurdles. The limited land area and heightened population density further magnify the urgency of addressing these challenges.

Despite these obstacles, El Salvador is committed to balancing development with conservation. Through strategic measures and a proactive stance, the country endeavors to ensure that its ecological treasures endure for future generations, fostering a delicate equilibrium between progress and

Climate

El Salvador's climate is characterized by a tropical warmth, with temperatures primarily dictated by elevation rather than distinct seasonal shifts. However, the country experiences different wet and dry seasons that shape its agricultural rhythms and natural landscapes.

El Salvador experiences its wet season and abundant rainfall from May to October. During this time, afternoon and evening showers are common, turning the land into lush greenery. In contrast, the dry season from November to April provides a break from the showers, with lower humidity and reduced rainfall. Despite the drier period, the country still receives some precipitation, ensuring a consistent water supply for its residents and ecosystems.

The average temperature in El Salvador is 25 °C (77 °F), but it can vary depending on the altitude and the time of year.

  • The Pacific coast of El Salvador is the hottest and most humid region of the country, with temperatures averaging around 27 °C (81 °F) year-round.

  • The central highlands are cooler and drier, with temperatures averaging around 22 °C (72 °F).

  • The northern mountains are the coolest region of the country, with temperatures averaging around 18 °C (64 °F).

El Salvador's climate is not without its challenges. The country lies within the hurricane belt, making it vulnerable to the wrath of these powerful storms. Hurricanes and tropical cyclones can wreak havoc on infrastructure, disrupt agriculture, and displace communities. Despite these risks, El Salvador's climate remains a defining feature of its identity, shaping its landscapes, influencing its culture, and contributing to its rich biodiversity.

Volcanism

El Salvador, situated within the Pacific Ring of Fire, a region renowned for its volcanic activity, is home to numerous volcanoes and volcanic structures that have shaped its landscapes and geology. Like the rest of Central America, the relatively stable Caribbean Plate is underneath El Salvador. The subduction of the Cocos Plate to the west beneath the Caribbean Plate to the east is responsible for the high frequency of earthquakes and volcanic eruptions in the region.

Along the Central American Volcanic Arc, which spans the territory of El Salvador, there are approximately twenty volcanoes. However, only Izalco, Santa Ana, and San Miguel have been recently active. While El Salvador's volcanoes offer benefits like geothermal energy resources and fertile volcanic soils for agriculture, they also present challenges. The proximity of human settlements to active volcanoes introduces potential risks, necessitating a balanced approach to harnessing the advantages while ensuring the population's safety.

Natural Geography of El Salvador

El Salvador's geography is a captivating interplay of mountain ranges, plateaus, and coastal plains shaped by the forces of nature over millennia. Two parallel mountain ranges traverse the country from west to east, enclosing a central plateau and leaving a narrow coastal plain along the Pacific Ocean. This unique topography divides the country into three distinct geographic regions:

  1. Northern Lowlands

  2. Central Plateau or Highlands, surrounded by volcanoes

  3. Pacific Coastal Belt

Northern Lowlands (La Zona Norte)

Stretching along the border with Honduras, the Sierra Madre mountain range defines the northern lowlands of El Salvador. Parallel to these mountains, a vast interior plain unfolds at elevations ranging from 400 to 600 m (1,300 to 2,000 ft). Once covered in forests, this interior plain has undergone significant transformation and now bears the marks of erosion from overexploitation. The consequences are evident in its semi-barren state today. Once rich in biodiversity, this area is now the country's most sparsely populated zone, illustrating the delicate balance between human activities and the preservation of natural landscapes.

Central Highlands (La Zona Central)

The central highlands prominently shape El Salvador's landscape, featuring a west-east discontinuous chain of volcanoes; some are currently active and categorized into five groups. This volcanic range encompasses a total of 20 cones. Beginning with the westernmost group near the Guatemalan border, notable peaks include Izalco and Santa Ana. The chain continues through San Salvador and San Miguel, reaching its easternmost point with the Conchagua group. These volcanoes are separated by alluvial basins and rolling hills, collectively known as the central plain. Positioned at elevations ranging from 1,000 to 1,500 m (3,500 to 5,000 ft), these plains feature fertile soils that have supported agriculture for an extended period.

Coastal Belt (La Costa)

Southward, as the central highlands yield to the Pacific coast, emerges a slender coastal plain characterized by average elevations ranging from 30 to 150 m (100 to 500 ft). The width of this coastal belt varies from 1 to 32 km (.5 to 20 mi), with the broadest section situated in the east, adjacent to the Gulf of Fonseca.
