Temperature Controls in the city of San Salvador in El Salvador

The capital city of El Salvador is San Salvador, with a longitude of 13.69 degrees North and a latitude of 89.19 degrees West. The warmest month in San Salvador is April with an average monthly temperature of 78.8 degrees fahrenheit, and the coldest month is in December with an average monthly temperature of 73.4 degrees fahrenheit (Holiday Weather). Based off of this information the annual range of temperature for the city is a whopping 5.4 degrees fahrenheit. So you might be curious as to what might cause such a significant variation in monthly temperatures. Well thanks to Country Studies, your curiosity will be gratified! They explain that from the months of November to April, the northeast tradewinds have a major impact on weather patterns. Air is coming in from the Caribbean, and most of its precipitation is "wrung out" on the way to San Salvador as it passes through the mountains of Honduras. When this air reaches the city it has become dry, hot, and hazy. Elevation is also an obvious temperature control for the country. The country has the coldest temperatures up in the mountains, and the hottest down in the central plateau. Although there are many temperature controls that affect the city's temperature, San Salvador's central location in the country would probably negate any strong temperature differential influences from ocean currents. 

When thinking about the future of San Salvador's climate, one could foresee a few issues that could arise in time. Agriculture in El Salvador makes up a big part of the country's economy, and because of this erosion could play a catastrophic role during heavy rain (perhaps due to deforestation). This could cause a snowball effect that contributes to surface temperature rise. Also, the coastal areas of the country could possibly be affected by rising sea levels, and that impacts San Salvador because it could potentially displace large amounts of the population. If the sea levels rise high enough, they could cause flooding from river basins that could lead to agricultural losses. After reading this, you might consider putting El Salvador on your bucket list destination in the rapidly disappearing countries section.
