==Geography==
[[File:Lago Ilopango desde Cojutepeque 2011.jpg|thumb|View of Lake Ilopango and the eastern San Salvador Valley]]
The city is located in the Boquerón Volcano Valley, a region of high seismic activity. The city's average elevation is {{convert|659|m|0|abbr=off|sp=us}} [[Above mean sea level|above sea level]], but ranges from a highest point of {{convert|1186|m|0|abbr=off|sp=us}} above sea level to a lowest point of {{convert|596|m|0|abbr=on}} above sea level.

The municipality is surrounded by these natural features of the landscape: the Acelhuate River on the east, the San Jacinto Hill on the south east, El Picacho Mountain and the Bicentennial Park on the West, North by the San Antonio River, southward by the ''Cordillera del Balsamo'' (Balsam Mountain Range); westward by the Boquerón Volcano and ''Cerro El Picacho'', the highest point in the municipality at {{convert|1929|m|0|abbr=on}}.

El Boquerón Volcano was dormant since its last eruption in 1917, but has been active recently. East of the municipality lies the San Jacinto Hill and the caldera of [[Lake Ilopango]], the largest natural body of water in the country with an area of {{convert|72|km2|0|abbr=off|sp=us}}. The caldera is seismically active, but has not erupted since 1880.

===Climate===
San Salvador has a [[tropical wet and dry climate]] under the [[Köppen climate classification]], and enjoys very warm to hot weather all year round, with daily mean temperatures of {{convert|27|°C|1|disp=or}}. Its average elevation of {{convert|658|m|ft|abbr=off|sp=us}} causes the city to experience slightly cooler temperatures in the mornings, higher solar radiation, and greater [[diurnal air temperature variation]] (particularly during the dry season) than nearby cities at sea level such as [[Acajutla]]. Its weather cools from the months of November through February due to seasonal winds of the dry season. During these months one can expect a daily mean of {{convert|22.2|°C|1}}. The hottest months of the year are April and May, during the transition from the dry season (November to April), to the rainy season (May to October). In April and May average maximum temperatures reach {{convert|32.2|°C|1}}. The highest reading ever recorded was {{convert|38.5|°C|°F|1}}, the lowest was {{convert|8.2|°C|°F|1}}. The highest [[dew point]] was {{convert|27|°C|°F}} and the lowest {{convert|-10|°C|°F}}. Thunderstorms occur almost daily during the rainy season, mostly in the afternoon and through the night—by morning the sky clears and the days are usually sunny until the afternoon storms.

===Topography===
[[File:Panoaa8.jpg|thumb|San Salvador City lies at the foot of San Salvador volcano.]]
San Salvador has a very hilly terrain; there are few parts of the municipality where the elevation is consistent. The city shares many topographic features with neighboring municipalities in the San Salvador and the La Libertad departments.

The most notable topographical feature visible in San Salvador and its metropolitan area is the ''Boquerón Volcano'', which looms over this region in its foothills at a height of {{convert|1893|m|0|abbr=off|sp=us}} [[Above mean sea level|above sea level]].

San Salvador shares ''Cerro El Picacho'', {{convert|1931|m|0|abbr=off|sp=us}} above sea level, with the neighboring municipality of [[Mejicanos]].

The portion of the ''Cordillera del Bálsamo'' ''(Balsam Mountain Range)'' that sits in the Municipality has an average elevation of {{convert|1030|m|0|abbr=off|sp=us}} [[Above mean sea level|above sea level]]. The ''Cordillera del Bálsamo'' is named after the [[Myroxylon]] balsamum tree, one of two species of [[Central American]] and [[South America]]n trees in the family Fabaceae (Leguminosae). The tree, often called ''Quina'' or ''Bálsamo'', is well known in the western world as the source of [[Balsam of Peru]] and [[Tolu balsam]]. El Salvador is the main exporter of these resins, which are still extracted manually.

''El Cerro de San Jacinto'' ''(San Jacinto Hill)'', is located on the eastern border of the municipality and is shared with [[Soyapango]], [[Santo Tomás, El Salvador|Santo Tomás]] and [[San Marcos, El Salvador|San Marcos]]. The summit is located at {{convert|1153|m|0|abbr=off|sp=us}} above sea level. The hill was once famous for the San Jacinto Cable Car and Park located at its summit, but the facilities were eventually abandoned. Soil types include [[regosols|regosol]], [[latosol]], and [[andosols|andosol]], as well as soils derived from [[andesitic]] and [[basaltic]] rocks.

===Bodies of water===
[[File:Ilopango caldera.jpg|thumb|Aerial view of [[Lake Ilopango]] caldera.]]

The river nearest San Salvador is the ''Acelhuate'', which is {{convert|2.2|km|1|abbr=on}} long. Although not within the municipality, it forms a natural boundary between San Salvador and Soyapango. The ''Acelhuate'' served as a water source for San Salvador during the late 1800s and early 1900s, but due to urbanization is now polluted. There are small streams running down from Lake Ilopango, and a few old aqueduct systems, but the municipality itself has no major bodies of water.

[[Lake Ilopango]], although not located in the municipality, is the closest large body of water, being only minutes away from the San Salvador historic center. The lake is also the largest natural body of water in the country, with an area of {{convert|72|km²|0|abbr=on}}. The Cerrón Grande Reservoir, {{convert|78|km|0|abbr=on}} north of San Salvador, was formed by damming the [[Lempa River]] in the municipalities of Potonico, (Chalatenango) and Jutiapa (Cabañas). The [[Cerrón Grande Dam]] provides a substantial portion of the region's [[Electricity sector in El Salvador|electricity]].
